1 00:00:03,266 --> 00:00:07,100 [narrator] A strange tomb is uncovered in Egypt's Valley of the Kings. 2 00:00:07,967 --> 00:00:09,700 But while excavating below the temple, 3 00:00:10,667 --> 00:00:13,266 a wooden coffin was discovered largely intact. 4 00:00:14,433 --> 00:00:17,900 But the most arresting aspect of the mummy was its face. 5 00:00:18,700 --> 00:00:21,367 It was open mouth as if screaming. 6 00:00:22,400 --> 00:00:24,767 So who was this person and what happened to her? 7 00:00:26,000 --> 00:00:28,266 A team of archaeologists is studying aerial footage in Iraq 8 00:00:29,133 --> 00:00:30,667 when they make a surprising discovery. 9 00:00:31,767 --> 00:00:33,500 The images showed evidence of the subsurface remains 10 00:00:34,467 --> 00:00:35,767 of a huge complex that had gone undiscovered 11 00:00:36,734 --> 00:00:38,400 up until that point. But what was this place? 12 00:00:39,200 --> 00:00:40,400 In the vast desert of New Mexico, 13 00:00:41,367 --> 00:00:43,266 researchers unearthed an ancient roadway. 14 00:00:43,934 --> 00:00:45,800 But this was no modern road. 15 00:00:46,834 --> 00:00:49,767 Its origins went back roughly a thousand years. 16 00:00:50,734 --> 00:00:52,367 It was assumed the road was somehow connected 17 00:00:53,400 --> 00:00:55,767 to the Pueblo settlements, but its exact purpose 18 00:00:56,433 --> 00:00:58,100 and function was a mystery. 19 00:01:00,300 --> 00:01:01,667 Ancient lost cities... 20 00:01:03,467 --> 00:01:04,667 ...forgotten treasures... 21 00:01:05,800 --> 00:01:07,300 ...mysterious structures. 22 00:01:08,533 --> 00:01:12,367 As new technology uncovers remarkable tales hidden beneath 23 00:01:13,567 --> 00:01:16,367 the deserts of the world, the "Secrets in the Sand" will 24 00:01:17,000 --> 00:01:18,667 will finally be revealed. 25 00:01:30,100 --> 00:01:33,200 East of Egypt's Nile River, the city of Luxor 26 00:01:34,367 --> 00:01:38,367 spreads across a dry flood plain for 150 square miles. 27 00:01:39,467 --> 00:01:43,367 Like most of Egypt, Luxor has a hot desert climate, 28 00:01:44,400 --> 00:01:46,266 making it clear and sunny pretty much every day. 29 00:01:47,333 --> 00:01:49,800 It's so dry that a year can pass without a single 30 00:01:50,233 --> 00:01:50,967 drop of rain. 31 00:01:52,066 --> 00:01:53,867 And yes, the Nile does provide water for agriculture, 32 00:01:54,934 --> 00:01:56,100 but the surrounding geography is as dry as a bone. 33 00:01:57,166 --> 00:01:59,200 You've got desert landscapes, rolling sand dunes, 34 00:01:59,900 --> 00:02:01,100 rocky plateau, and mountains. 35 00:02:02,367 --> 00:02:06,567 Today, the city is a thriving center of commerce 36 00:02:07,734 --> 00:02:12,600 and industry, but Luxor is best known as the former city 37 00:02:13,667 --> 00:02:16,200 of Thebes, capital of Upper Egypt during the Middle 38 00:02:16,767 --> 00:02:17,800 and New Kingdom eras. 39 00:02:18,900 --> 00:02:22,100 Thebes first rose to prominence in the 4th century BCE 40 00:02:22,767 --> 00:02:24,000 after the Peloponnesian War, 41 00:02:24,867 --> 00:02:27,166 when it became a major military force. 42 00:02:28,100 --> 00:02:30,400 And it remained a powerful capital for most 43 00:02:31,066 --> 00:02:32,867 of the following 500 years. 44 00:02:34,100 --> 00:02:36,100 Many of the ancient monuments and temples can still be seen 45 00:02:36,967 --> 00:02:38,467 dotting the urban landscape of Luxor. 46 00:02:39,367 --> 00:02:41,166 On the west bank is the Theban Necropolis, 47 00:02:41,967 --> 00:02:43,166 featuring the Valley of the Kings, 48 00:02:44,300 --> 00:02:46,467 an ancient burial ground for Egyptian pharaohs, noblemen, 49 00:02:47,533 --> 00:02:50,567 and their families from the 18th to the 20th Dynasty. 50 00:02:51,567 --> 00:02:53,300 A team of archaeologists is excavating a tomb 51 00:02:53,934 --> 00:02:54,900 in the Valley of the Kings 52 00:02:55,767 --> 00:02:58,100 when they make a surprising discovery. 53 00:02:59,133 --> 00:03:00,700 There's a long row of connected mortuary temples 54 00:03:01,500 --> 00:03:03,100 in a valley called Deir el-Bahari. 55 00:03:03,967 --> 00:03:05,767 That's an Arabic name for a monastery. 56 00:03:06,834 --> 00:03:09,000 Below the temples is a series of individual tombs, 57 00:03:10,000 --> 00:03:12,000 including one temple for the site's architect, 58 00:03:12,800 --> 00:03:14,467 Senenmut, along with his parents. 59 00:03:15,333 --> 00:03:17,000 But while excavating below the temple, 60 00:03:18,000 --> 00:03:21,066 a wooden coffin was discovered, largely intact. 61 00:03:22,166 --> 00:03:24,400 [Dr. Agbedor] The coffin was opened to reveal a mummy, 62 00:03:25,100 --> 00:03:28,867 also intact, of an adult female. 63 00:03:30,066 --> 00:03:32,667 It was laying on its back with extended legs and both arms 64 00:03:33,900 --> 00:03:37,667 were angled inward so the hands were covering the pelvic area. 65 00:03:38,834 --> 00:03:42,467 But the most arresting aspect of the mummy was its face. 66 00:03:43,266 --> 00:03:45,767 It was open mouth as if screaming. 67 00:03:46,800 --> 00:03:49,867 So who was this person and what happened to her? 68 00:03:51,033 --> 00:03:52,367 [Dr. Cantor] The mummy was just over five feet in length 69 00:03:52,900 --> 00:03:53,500 from heel to crown. 70 00:03:54,600 --> 00:03:56,967 Its reddish brown skin was hard and thick and intact. 71 00:03:58,133 --> 00:04:00,367 Its fingernails and toenails were also all accounted for, 72 00:04:01,433 --> 00:04:02,767 and while some of the mummy's teeth were missing, 73 00:04:03,734 --> 00:04:06,800 those present were large, white, and strong. 74 00:04:07,734 --> 00:04:09,767 Aside from the open mouth scream position, 75 00:04:10,934 --> 00:04:13,400 the other notable feature was a large, thick wig braided 76 00:04:14,200 --> 00:04:15,700 right into the mummy's sparse hair 77 00:04:16,367 --> 00:04:17,867 on either side of the skull. 78 00:04:18,734 --> 00:04:20,100 The wig was composed of dark human hair 79 00:04:21,133 --> 00:04:23,367 falling to the shoulders as opposed to being bound, 80 00:04:23,934 --> 00:04:24,867 as was the tradition. 81 00:04:25,667 --> 00:04:26,967 So is it possible the mummy's wig 82 00:04:27,934 --> 00:04:31,000 could be a clue to her identity and her fate? 83 00:04:31,867 --> 00:04:33,066 The use of wigs and hair extensions 84 00:04:34,000 --> 00:04:35,567 is an illustration of the Egyptians' desire 85 00:04:36,734 --> 00:04:39,667 to attain physical beauty through lavish accessories. 86 00:04:40,800 --> 00:04:42,000 [Dr. Riskin] Wigs and extensions were frequently used 87 00:04:42,667 --> 00:04:43,767 in Egyptian funerary rites, 88 00:04:44,700 --> 00:04:46,000 along with other symbols of wealth and power, 89 00:04:46,800 --> 00:04:48,600 like precious amulets and jewelry. 90 00:04:49,633 --> 00:04:52,667 But those were all also worn by living Egyptians, 91 00:04:53,500 --> 00:04:54,867 men and women, for the same reasons, 92 00:04:55,767 --> 00:04:58,700 to indicate their socioeconomic status. 93 00:04:59,633 --> 00:05:01,567 Egyptians crafted the wigs from human hair 94 00:05:02,600 --> 00:05:05,400 and supplemented them with plant or flax fibers. 95 00:05:06,467 --> 00:05:09,367 It's believed that dark or black hair was preferred 96 00:05:10,166 --> 00:05:12,500 as it represented youthful beauty. 97 00:05:13,567 --> 00:05:15,567 And while a lot of effort went into the aesthetics 98 00:05:16,400 --> 00:05:18,200 such as styling with curls and braids, 99 00:05:18,867 --> 00:05:20,500 the wigs were also practical 100 00:05:21,467 --> 00:05:23,166 as they protected shaven scalp from the sun 101 00:05:24,066 --> 00:05:26,767 and maintained hygiene by reducing lice. 102 00:05:27,867 --> 00:05:29,567 The close examination of the Screaming Woman's wig 103 00:05:30,300 --> 00:05:31,700 leads to a critical connection. 104 00:05:32,900 --> 00:05:35,567 The mummy's wig was cleaved in two halves down the center, 105 00:05:36,433 --> 00:05:38,166 much like a middle part of natural hair, 106 00:05:39,233 --> 00:05:41,266 and the braids were tapered slightly at each end. 107 00:05:42,233 --> 00:05:43,667 It was an arrangement that was very similar 108 00:05:44,633 --> 00:05:47,266 to that of another female mummy buried nearby, 109 00:05:48,400 --> 00:05:51,300 the mother of the tomb's designer and builder, Senenmut. 110 00:05:52,400 --> 00:05:54,066 Senenmut is best known today for being the architect 111 00:05:55,000 --> 00:05:57,000 of the mortuary temple of Queen Hatshepsut, 112 00:05:58,066 --> 00:06:00,266 a female pharaoh who ruled for more than 20 years, 113 00:06:00,834 --> 00:06:02,767 starting in 1479 BCE. 114 00:06:03,533 --> 00:06:05,500 Her temple was a stunning example 115 00:06:06,700 --> 00:06:09,767 of ancient Egyptian design, with three levels of terraces 116 00:06:10,333 --> 00:06:12,400 all connected by ramps. 117 00:06:13,533 --> 00:06:17,100 As chief architect, Senenmut would have had high status 118 00:06:17,667 --> 00:06:19,166 in Hatshepsut's court. 119 00:06:20,233 --> 00:06:22,467 And with that, he was entitled to such privileges 120 00:06:23,400 --> 00:06:26,300 as securing a burial spot for his parents 121 00:06:27,066 --> 00:06:28,600 among the royals and other elites. 122 00:06:29,867 --> 00:06:33,800 However, while Senenmut's own tomb was to be built 123 00:06:34,600 --> 00:06:35,967 under Queen Hatshepsut's courtyard, 124 00:06:36,967 --> 00:06:40,100 along with his parents, it was never completed. 125 00:06:41,467 --> 00:06:43,367 [Dr. Cantor] Even more mysterious is the fate of Senenmut himself. 126 00:06:44,567 --> 00:06:46,800 He left public life abruptly, and we still don't know why. 127 00:06:47,900 --> 00:06:50,000 And his remains were never interred in his elaborate 128 00:06:50,533 --> 00:06:51,967 but unfinished tomb. 129 00:06:53,033 --> 00:06:55,867 With so many open questions surrounding Senenmut, 130 00:06:56,867 --> 00:06:57,900 we can't conclude with any degree of certainty 131 00:06:59,033 --> 00:07:01,367 that the Screaming Woman was a relative of the architect. 132 00:07:01,967 --> 00:07:03,066 Professor Sahar Saleem, 133 00:07:04,333 --> 00:07:05,700 whose forensic and historical analysis of the Screaming Mummy 134 00:07:06,266 --> 00:07:07,567 revealed another clue. 135 00:07:08,500 --> 00:07:09,800 All of the vital organs, including the brain 136 00:07:10,700 --> 00:07:12,166 of the Screaming Woman, were still intact, 137 00:07:13,333 --> 00:07:15,266 and there was a complete absence of incisions to the body. 138 00:07:16,200 --> 00:07:17,100 This was inconsistent with the traditional 139 00:07:18,233 --> 00:07:21,100 Egyptian embalming process for high status individuals, 140 00:07:22,233 --> 00:07:24,467 in which the body's viscera was removed before burial. 141 00:07:25,700 --> 00:07:27,100 [Dr. Riskin] It's possible that the people doing the embalming 142 00:07:28,033 --> 00:07:29,166 did a sloppy job, maybe they were rushed, 143 00:07:30,233 --> 00:07:30,767 maybe they just didn't know what they were doing, 144 00:07:31,600 --> 00:07:33,000 they were incompetent, I don't know. 145 00:07:33,633 --> 00:07:34,200 That feels unlikely to me. 146 00:07:35,200 --> 00:07:36,867 I think a better explanation is that the mummy, 147 00:07:37,767 --> 00:07:39,667 the Screaming Woman, just wasn't a member 148 00:07:40,667 --> 00:07:42,266 of the royal family or the elite class at all. 149 00:07:43,233 --> 00:07:45,300 That idea is supported by the fact that aside 150 00:07:46,200 --> 00:07:47,600 from two scarab rings on her left hand, 151 00:07:48,567 --> 00:07:50,367 there were practically no jewels or ornaments 152 00:07:51,500 --> 00:07:54,000 or grave goods on the mummy or surrounding the coffin. 153 00:07:55,400 --> 00:07:57,567 Also, her recumbent body position, 154 00:07:58,600 --> 00:08:00,467 where both arms were inclined toward her groin, 155 00:08:01,467 --> 00:08:03,400 was inconsistent with other elite women's burials 156 00:08:03,934 --> 00:08:04,767 in the New Kingdom. 157 00:08:05,567 --> 00:08:06,667 Female members of the royal family 158 00:08:07,667 --> 00:08:08,967 were typically buried with the left arm flexed 159 00:08:09,934 --> 00:08:12,066 across the chest and the right arm to the side. 160 00:08:13,000 --> 00:08:15,000 So is it possible that the Screaming Woman 161 00:08:15,967 --> 00:08:17,500 was some kind of outlier, a commoner buried 162 00:08:18,133 --> 00:08:18,700 among the elite of Egypt? 163 00:08:27,400 --> 00:08:30,000 A team of archaeologists is excavating a tomb 164 00:08:30,633 --> 00:08:31,567 in the Valley of the Kings 165 00:08:32,433 --> 00:08:34,266 when they make a surprising discovery, 166 00:08:34,800 --> 00:08:35,700 The Screaming Woman. 167 00:08:36,633 --> 00:08:38,700 The Egyptians believed that it was critical 168 00:08:39,767 --> 00:08:41,867 to preserve the bodies of their pharaohs and kings 169 00:08:43,000 --> 00:08:45,166 in order to ensure their safe passage into the afterlife. 170 00:08:46,000 --> 00:08:47,200 This involved removing vital organs, 171 00:08:48,100 --> 00:08:50,266 but also dehydrating the body with salt, 172 00:08:51,033 --> 00:08:51,800 and then covering the dried skin 173 00:08:52,700 --> 00:08:54,367 with a blend of natural substances, oils, 174 00:08:55,200 --> 00:08:57,567 fats, and resins, to prevent decay. 175 00:08:58,800 --> 00:09:00,567 Samples taken from the skin of the Screaming Woman revealed 176 00:09:01,700 --> 00:09:04,266 she'd been embalmed with juniper and frankincense resin. 177 00:09:05,066 --> 00:09:06,400 Not only were these costly items, 178 00:09:07,200 --> 00:09:08,567 but they likely had to be imported 179 00:09:09,233 --> 00:09:10,600 from neighboring countries. 180 00:09:11,700 --> 00:09:14,600 Hair fibers from the wig had been dyed red with henna, 181 00:09:15,567 --> 00:09:17,467 a rare dye prepared with the powdered leaves 182 00:09:17,967 --> 00:09:19,100 of the henna tree. 183 00:09:20,300 --> 00:09:23,166 Taken together, the expensive imported embalming materials 184 00:09:23,934 --> 00:09:24,700 plus the well-preserved condition 185 00:09:25,900 --> 00:09:29,100 of the Screaming Woman's body indicate that her burial was 186 00:09:30,133 --> 00:09:32,400 consistent with those of the pharaohs and elites 187 00:09:32,934 --> 00:09:33,667 that surrounded her. 188 00:09:34,834 --> 00:09:37,867 So maybe she was a member of that elite class after all. 189 00:09:38,700 --> 00:09:40,367 Although rare, the Screaming Woman 190 00:09:41,367 --> 00:09:42,767 isn't the only mummy in Egypt to be discovered 191 00:09:43,400 --> 00:09:45,166 with its mouth open wide. 192 00:09:46,300 --> 00:09:48,867 During the 18th Dynasty, Princess Ahmose-Meritamun became 193 00:09:49,834 --> 00:09:51,667 the great royal wife of her younger brother, 194 00:09:52,233 --> 00:09:54,100 the Pharaoh Amenhotep I. 195 00:09:55,133 --> 00:09:56,867 As with the Screaming Woman, Meritamun's remains 196 00:09:57,633 --> 00:09:58,567 were discovered in a wooden coffin 197 00:09:59,266 --> 00:10:00,667 in the Deir el-Bahari section 198 00:10:01,300 --> 00:10:02,166 of the Theban Necropolis. 199 00:10:03,066 --> 00:10:06,266 Her face also an open mouth death mask. 200 00:10:07,066 --> 00:10:08,567 A CT scan of Meritamun's skeleton 201 00:10:09,367 --> 00:10:10,567 revealed the young queen had suffered 202 00:10:11,266 --> 00:10:12,700 from sclerosis and arthritis, 203 00:10:13,600 --> 00:10:15,467 both of which can result in bone curvatures 204 00:10:16,367 --> 00:10:18,467 and constrictions of the body's joints. 205 00:10:19,667 --> 00:10:21,266 These findings indicate she may have died of a heart attack, 206 00:10:22,433 --> 00:10:24,800 and her body was not found before rigor mortis kicked in. 207 00:10:25,967 --> 00:10:28,867 And Meritamun's open mouth was likely due to the natural 208 00:10:29,567 --> 00:10:31,000 postmortem muscle relaxation. 209 00:10:31,433 --> 00:10:32,600 So it's possible 210 00:10:33,433 --> 00:10:34,400 that the Screaming Woman's open mouth 211 00:10:35,600 --> 00:10:37,867 was a direct result of a serious health condition or disease. 212 00:10:38,834 --> 00:10:40,667 If that's the case, is that what killed her? 213 00:10:41,567 --> 00:10:43,166 A CT scan performed on the mummy leads 214 00:10:43,667 --> 00:10:44,467 to a breakthrough. 215 00:10:45,500 --> 00:10:46,500 The opening and closing of the mouth is controlled 216 00:10:47,700 --> 00:10:49,600 by a bunch of muscles around the temporal mandibular joint. 217 00:10:50,467 --> 00:10:51,500 Ordinarily, when those muscles relax, 218 00:10:52,400 --> 00:10:53,367 like when you're asleep or after you die, 219 00:10:54,066 --> 00:10:54,567 the mouth opens a little bit, 220 00:10:55,533 --> 00:10:57,967 but this extreme gait, this wide open mouth, 221 00:10:58,834 --> 00:11:00,600 suggests that the muscles were firing. 222 00:11:01,633 --> 00:11:04,266 So did that happen after death from rigor mortis, 223 00:11:05,300 --> 00:11:06,700 or is this something that happened during death? 224 00:11:07,500 --> 00:11:09,500 To keep the mouth closed for burial, 225 00:11:10,266 --> 00:11:12,000 Egyptian embalmers typically wrap 226 00:11:12,567 --> 00:11:14,266 the deceased's mandible 227 00:11:15,066 --> 00:11:17,000 around the skull, keeping it shut. 228 00:11:17,967 --> 00:11:19,800 But the Screaming Woman's mouth was discovered 229 00:11:20,500 --> 00:11:22,266 in an unnaturally wide position, 230 00:11:23,400 --> 00:11:25,467 as if she had been crying out in agony when she died. 231 00:11:25,767 --> 00:11:26,767 [scream] 232 00:11:27,600 --> 00:11:28,700 And there's a biological phenomenon 233 00:11:29,400 --> 00:11:30,667 that supports this possibility, 234 00:11:31,533 --> 00:11:33,367 a rare event called a cadaveric spasm, 235 00:11:34,533 --> 00:11:36,667 which causes muscles to freeze in the position the person 236 00:11:37,767 --> 00:11:40,467 was in at the time of death, not unlike rigor mortis. 237 00:11:41,700 --> 00:11:43,867 [Anthea] Cadaveric spasms are usually associated with brutal, 238 00:11:44,533 --> 00:11:45,867 violent deaths under extreme 239 00:11:46,667 --> 00:11:49,166 physical conditions and emotions. 240 00:11:50,233 --> 00:11:51,967 So while the exact cause of death can't be determined 241 00:11:52,867 --> 00:11:54,567 for the Screaming Woman, nor her identity, 242 00:11:55,500 --> 00:11:57,467 the expression on her face certainly aligns 243 00:11:58,166 --> 00:12:00,467 with intense suffering and pain. 244 00:12:01,567 --> 00:12:03,767 The screaming mummy remains a fascinating curiosity 245 00:12:05,000 --> 00:12:07,600 and its discovery offers a true time capsule for just one 246 00:12:08,467 --> 00:12:09,967 of the human mysteries of ancient Egypt 247 00:12:10,533 --> 00:12:11,100 waiting to be solved. 248 00:12:25,166 --> 00:12:30,000 Roughly 185 miles southeast of Baghdad lies Tello, Iraq, 249 00:12:30,834 --> 00:12:32,266 a city in the Dhi Qar Governorate. 250 00:12:33,333 --> 00:12:35,166 The region is known as the cradle of civilization 251 00:12:36,033 --> 00:12:37,066 because it was home to the Sumerians, 252 00:12:37,934 --> 00:12:40,000 the oldest known culture in Mesopotamia. 253 00:12:41,100 --> 00:12:42,867 They were responsible for a host of human advancements, 254 00:12:43,767 --> 00:12:44,500 including the development of cuneiform, 255 00:12:45,433 --> 00:12:46,767 one of the earliest known writing systems 256 00:12:47,567 --> 00:12:48,667 that involved engraving pictograms 257 00:12:49,600 --> 00:12:52,000 and symbols into clay with a reed stylus. 258 00:12:52,767 --> 00:12:53,667 The Sumerians were also pioneers 259 00:12:54,433 --> 00:12:56,100 in math, science, architecture, 260 00:12:57,233 --> 00:12:59,100 and societal organization, all of which helped to build 261 00:13:00,066 --> 00:13:02,100 the foundations for future civilizations. 262 00:13:03,300 --> 00:13:05,000 Archaeological evidence tells us that the Sumerians built 263 00:13:06,166 --> 00:13:08,867 about a dozen city-states in the fourth millennium BCE. 264 00:13:09,867 --> 00:13:11,867 These urban centers are the first known cities 265 00:13:12,367 --> 00:13:13,066 in world history. 266 00:13:14,233 --> 00:13:16,400 One of them, known as Girsu, stood where the modern city 267 00:13:17,166 --> 00:13:19,500 of Tello in Iraq is located today. 268 00:13:20,567 --> 00:13:24,300 At its peak, around 2500 BCE, Girsu was the heart 269 00:13:24,934 --> 00:13:26,100 of the Lagash city-state. 270 00:13:27,133 --> 00:13:29,200 The walled city covered an area around 600 acres, 271 00:13:30,233 --> 00:13:31,900 and some estimates put the population at between 272 00:13:32,533 --> 00:13:33,900 15,000 and 20,000 people. 273 00:13:35,200 --> 00:13:38,066 Girsu was first discovered in 1877 274 00:13:39,266 --> 00:13:42,266 by a French archaeologist, and it was extensively excavated 275 00:13:42,834 --> 00:13:44,800 over the next 56 years. 276 00:13:45,967 --> 00:13:48,100 But political instability and armed conflict in the area 277 00:13:49,200 --> 00:13:51,900 put a halt to any further exploration in the 1930s, 278 00:13:53,100 --> 00:13:57,200 and Girsu was largely forgotten about, but not by everyone. 279 00:13:58,300 --> 00:14:00,166 A team comprised of British and Iraqi archaeologists 280 00:14:01,033 --> 00:14:02,667 are analyzing drone footage of Girsu 281 00:14:03,567 --> 00:14:05,567 when they notice something unexpected. 282 00:14:06,667 --> 00:14:08,367 The images showed evidence of the subsurface remains 283 00:14:09,333 --> 00:14:11,100 of a huge complex that had gone undiscovered 284 00:14:12,066 --> 00:14:13,600 up until that point. So what was this place? 285 00:14:15,667 --> 00:14:19,367 Cuneiform tablets discovered by the French excavations claim 286 00:14:20,500 --> 00:14:22,767 that Girsu was considered a sacred city because it was 287 00:14:23,734 --> 00:14:25,900 said to be home to the sanctuary of Ningirsu, 288 00:14:27,000 --> 00:14:29,667 the Sumerian god of war, who was revered because he was 289 00:14:30,467 --> 00:14:32,166 believed to battle mythical beasts, 290 00:14:33,100 --> 00:14:34,567 which ensured the spring rains would come 291 00:14:35,500 --> 00:14:37,667 and provide water for the irrigation-based 292 00:14:38,467 --> 00:14:40,166 agricultural systems of the region. 293 00:14:41,400 --> 00:14:43,100 [Anthea] But the French teams were never able to locate this 294 00:14:43,934 --> 00:14:46,367 legendary temple dedicated to Ningirsu, 295 00:14:47,233 --> 00:14:48,367 leaving some doubt as to whether or not 296 00:14:48,800 --> 00:14:49,767 it even existed. 297 00:14:50,700 --> 00:14:52,400 So is it possible that the complex detected 298 00:14:53,400 --> 00:14:55,400 by the drone images is this elusive structure? 299 00:15:01,467 --> 00:15:04,867 In 2020, archaeologists investigating an area 300 00:15:06,066 --> 00:15:09,567 of Girsu known as Uruku, which means "The Sacred City " 301 00:15:10,500 --> 00:15:12,166 unearthed evidence of ceremonial practices 302 00:15:12,734 --> 00:15:13,867 dedicated to Ningirsu. 303 00:15:15,367 --> 00:15:16,800 It was a huge find. 304 00:15:17,800 --> 00:15:20,900 Over 300 broken ceremonial ceramic cups, bowls, 305 00:15:21,867 --> 00:15:24,667 jars, spouted vessels, and many animal bones. 306 00:15:25,734 --> 00:15:27,967 One of the artifacts found was a fragment of a vase 307 00:15:28,900 --> 00:15:31,066 with an inscription dedicated to Ningirsu. 308 00:15:31,934 --> 00:15:34,000 The items were in or near a ritual pit 309 00:15:35,100 --> 00:15:37,867 known as a "favissa" that was around eight feet deep. 310 00:15:38,700 --> 00:15:40,166 The vessels found were probably used 311 00:15:40,734 --> 00:15:41,867 in a ceremonial banquet 312 00:15:42,800 --> 00:15:44,400 before being ritually thrown into the pit, 313 00:15:45,467 --> 00:15:47,667 while the bones were likely the remains of animals 314 00:15:48,734 --> 00:15:51,266 that were either eaten or killed during sacrifices. 315 00:15:52,367 --> 00:15:54,367 The area also had a thick layer of ash, believed to be 316 00:15:55,166 --> 00:15:57,700 the remnants of large ritual fires. 317 00:15:58,667 --> 00:16:01,200 The ceremonial ceramics, the evidence of fire, 318 00:16:02,433 --> 00:16:04,266 and a favissa indicate that this is where religious gatherings 319 00:16:05,433 --> 00:16:07,967 took place and where the people of Girsu gathered to feast 320 00:16:08,667 --> 00:16:09,266 and pay respects to their gods. 321 00:16:10,700 --> 00:16:13,100 In 2024, researchers discovered 322 00:16:14,133 --> 00:16:16,867 a cuneiform tablet from the 15th century BCE 323 00:16:17,934 --> 00:16:19,967 at the Alalakh archaeological site in Reyhanli, 324 00:16:21,100 --> 00:16:22,667 a southern Turkish city near the border with Syria. 325 00:16:24,600 --> 00:16:27,367 At the time the tablet was inscribed, Alalakh was 326 00:16:28,533 --> 00:16:30,567 the capital of the kingdom of Mukish and the largest city 327 00:16:31,000 --> 00:16:32,000 in the region. 328 00:16:32,900 --> 00:16:34,567 It was occupied by the Amorites, a culture 329 00:16:35,200 --> 00:16:35,900 from western Mesopotamia. 330 00:16:37,266 --> 00:16:40,200 The tablet itself is tiny, measuring only 331 00:16:41,200 --> 00:16:45,867 1.6 by 0.6 inches, and weighing just 28 grams. 332 00:16:46,934 --> 00:16:48,367 It's written in Akkadian, one of the oldest known 333 00:16:48,867 --> 00:16:50,100 Semitic languages, 334 00:16:51,333 --> 00:16:53,367 and it's one that's no longer spoken anywhere in the world. 335 00:16:54,600 --> 00:16:57,867 Akkadian's cuneiform script was made up of around 600 signs, 336 00:16:59,000 --> 00:17:00,767 some of which represented full words, while some were 337 00:17:01,333 --> 00:17:01,867 just single syllables. 338 00:17:03,400 --> 00:17:06,100 When they translated the tablet, it was discovered 339 00:17:07,300 --> 00:17:10,767 that it details the purchase of chairs, tables, and stools 340 00:17:11,800 --> 00:17:14,300 by an unknown buyer, basically an ancient receipt 341 00:17:15,000 --> 00:17:16,567 or bill of sale for furniture. 342 00:17:17,567 --> 00:17:19,400 While it may seem like kind of a mundane item, 343 00:17:20,533 --> 00:17:23,166 it actually offers insights into the economic systems 344 00:17:24,066 --> 00:17:26,200 of the region during the Late Bronze Age. 345 00:17:27,433 --> 00:17:30,767 So maybe the tablets discovered at Girsu tell a similar story, 346 00:17:31,900 --> 00:17:34,567 and the complex isn't a temple, but rather a marketplace 347 00:17:35,200 --> 00:17:36,667 for business transactions. 348 00:17:37,800 --> 00:17:39,100 [Anthea] Sure enough, they unearth the mud-brick walls 349 00:17:39,867 --> 00:17:41,266 that make up the mystery complex, 350 00:17:42,066 --> 00:17:43,567 and the scope of it is staggering. 351 00:17:44,266 --> 00:17:45,700 This was no simple structure. 352 00:17:46,567 --> 00:17:47,767 There are what looks to be the remains 353 00:17:48,900 --> 00:17:51,667 of different buildings and multiple rooms and chambers. 354 00:17:52,734 --> 00:17:54,467 But that still doesn't tell us exactly what it was 355 00:17:55,133 --> 00:17:56,567 and what purpose it served. 356 00:17:57,633 --> 00:17:59,166 The cuneiform tablets are analyzed in the hopes 357 00:18:00,100 --> 00:18:01,066 that they will provide some answers, 358 00:18:02,133 --> 00:18:04,400 and the researchers are stunned by the results. 359 00:18:05,066 --> 00:18:06,100 The tablets are essentially 360 00:18:07,133 --> 00:18:08,500 the government's administrative archives of Girsu 361 00:18:09,400 --> 00:18:10,567 from when the city was under the control 362 00:18:11,533 --> 00:18:15,300 of the Akkad dynasty, from 2300 to 2150 BCE. 363 00:18:15,967 --> 00:18:17,467 This is an incredible find. 364 00:18:18,533 --> 00:18:21,100 It's the oldest physical evidence of the first empire 365 00:18:21,633 --> 00:18:22,867 in recorded history. 366 00:18:23,867 --> 00:18:25,900 Girsu was one of the Sumerian cities conquered 367 00:18:26,900 --> 00:18:31,066 by the Mesopotamian king Sargon around 2300 BCE. 368 00:18:32,233 --> 00:18:35,000 Sargon developed a new form of government by vanquishing 369 00:18:36,166 --> 00:18:38,400 all the Sumerian settlements and creating what many call 370 00:18:39,100 --> 00:18:40,967 the first empire in the world. 371 00:18:41,800 --> 00:18:43,266 Until the discovery of the tablets, 372 00:18:44,133 --> 00:18:45,900 information on this empire was scarce. 373 00:18:46,834 --> 00:18:48,767 The only documented records were fragments 374 00:18:49,467 --> 00:18:51,266 of royal inscriptions or copies 375 00:18:52,066 --> 00:18:54,166 of unreliable Akkadian inscriptions 376 00:18:54,700 --> 00:18:56,300 recorded much later. 377 00:18:57,533 --> 00:18:59,967 The tablets could be called the spreadsheets of the empire, 378 00:19:00,934 --> 00:19:02,467 and they reveal a complicated bureaucracy, 379 00:19:03,133 --> 00:19:04,166 Deliveries and expenditures 380 00:19:05,200 --> 00:19:07,266 on everything from textiles and precious stones, 381 00:19:08,033 --> 00:19:09,567 to fish and domesticated animals, 382 00:19:10,100 --> 00:19:11,467 to flour and barley. 383 00:19:12,467 --> 00:19:14,000 Some of the tablets even have maps of canals, 384 00:19:15,100 --> 00:19:17,266 architectural layouts of buildings, and other plans. 385 00:19:18,367 --> 00:19:21,400 Believed to have been built around 4,500 years ago, 386 00:19:22,467 --> 00:19:24,066 the Lord Palace of the Kings was the centerpiece 387 00:19:24,734 --> 00:19:25,700 of the grand city of Girsu, 388 00:19:26,533 --> 00:19:28,367 but it had been lost for centuries. 389 00:19:29,367 --> 00:19:31,166 The palace complex would've been a central part 390 00:19:31,734 --> 00:19:32,600 of Sumerian city life, 391 00:19:33,567 --> 00:19:35,066 with the king and his court residing there. 392 00:19:35,934 --> 00:19:36,900 It was also an administrative center, 393 00:19:38,133 --> 00:19:41,166 a hub for governing the city and its surrounding territories. 394 00:19:42,333 --> 00:19:45,100 Incredibly, other excavations at Girsu finally uncovered 395 00:19:46,233 --> 00:19:49,600 the main temple dedicated to Ningirsu, called E-ninnu, 396 00:19:50,700 --> 00:19:53,000 also known as the "Temple of the White Thunderbird." 397 00:19:53,900 --> 00:19:55,767 It was located near the palace complex, 398 00:19:57,000 --> 00:20:00,100 showing just how intertwined religious and imperial life were 399 00:20:00,767 --> 00:20:01,367 during the Sumerian period. 400 00:20:03,667 --> 00:20:06,867 Before these excavations, the existence of the palace 401 00:20:08,033 --> 00:20:09,367 and temple was only known because of passing references 402 00:20:10,133 --> 00:20:11,166 made to them that were discovered 403 00:20:11,867 --> 00:20:12,800 by the early French excavation. 404 00:20:13,934 --> 00:20:15,667 The Lord Palace of the King's discovery sheds light 405 00:20:16,567 --> 00:20:18,500 on the history, culture, and governance 406 00:20:19,400 --> 00:20:20,767 of the ancient Sumerian civilization, 407 00:20:21,834 --> 00:20:23,367 and offers valuable insight into the daily life 408 00:20:24,333 --> 00:20:26,066 of one of the oldest cities on the planet. 409 00:20:37,266 --> 00:20:39,567 The Northwestern region of Arabia extends 410 00:20:40,700 --> 00:20:43,266 tens of thousands of miles between modern-day Jordan 411 00:20:44,000 --> 00:20:44,900 and into the ecoregion of Iraq. 412 00:20:46,200 --> 00:20:49,967 This is a vast, incredibly arid ecoregion 413 00:20:50,834 --> 00:20:52,567 with annual rainfall generally between 414 00:20:53,200 --> 00:20:54,266 just two and eight inches. 415 00:20:55,266 --> 00:20:56,700 There are also extreme temperature variations, 416 00:20:57,934 --> 00:21:00,367 with lows of just 35 degrees in winter and highs reaching up 417 00:21:01,033 --> 00:21:02,266 above 100 degrees in summer. 418 00:21:04,567 --> 00:21:06,367 Plants like small shrubs 419 00:21:07,500 --> 00:21:10,200 and certain hardy desert flowers do actually grow here, 420 00:21:11,300 --> 00:21:13,400 and the animal species in the area include predators 421 00:21:14,300 --> 00:21:16,967 like foxes, caracals, and honey badgers, 422 00:21:17,867 --> 00:21:19,900 as well as herds of ibexes and antelopes. 423 00:21:21,700 --> 00:21:25,800 These animals graze alongside domesticated herds of cattle, 424 00:21:26,967 --> 00:21:29,367 sheep, and goats who belong to the nomadic pastoralists 425 00:21:30,066 --> 00:21:31,367 who live throughout the desert. 426 00:21:32,266 --> 00:21:34,300 In fact, despite the inhospitable climate, 427 00:21:35,333 --> 00:21:37,000 the region has a rich history of human presence 428 00:21:37,700 --> 00:21:39,867 dating back thousands of years. 429 00:21:40,900 --> 00:21:42,867 In Saudi Arabia, a team working at the Al-Natah 430 00:21:43,900 --> 00:21:45,867 archaeological site notice an unusual structure 431 00:21:46,667 --> 00:21:48,800 rising out of the desert landscape. 432 00:21:49,967 --> 00:21:51,967 The outer reaches of the site are marked by the remains 433 00:21:52,500 --> 00:21:53,900 of an enormous wall. 434 00:21:55,166 --> 00:21:57,367 In some places, there are only a few piles of brick to tell us 435 00:21:58,633 --> 00:22:02,100 where it stood, and other parts are covered in piles of rubble. 436 00:22:03,200 --> 00:22:05,000 Still, based on the existing evidence, it's estimated 437 00:22:05,900 --> 00:22:08,800 to have once been over nine miles long. 438 00:22:09,700 --> 00:22:10,266 The southern reaches of the site show us 439 00:22:11,100 --> 00:22:12,800 how formidable this wall really was. 440 00:22:13,667 --> 00:22:15,800 Here, the ruins are up to 19 feet thick, 441 00:22:16,500 --> 00:22:17,667 and two large towers were added. 442 00:22:18,734 --> 00:22:20,266 A fortification this huge, with defensive features 443 00:22:21,233 --> 00:22:23,166 like these, was likely built for protection. 444 00:22:23,834 --> 00:22:25,100 The question is, from what? 445 00:22:33,100 --> 00:22:35,967 Excavations in the central area of the Al-Natah site 446 00:22:37,100 --> 00:22:40,066 yield another discovery that raises more questions. 447 00:22:40,934 --> 00:22:42,066 There's a group of tall circular towers 448 00:22:42,700 --> 00:22:44,367 with high, stepped walls. 449 00:22:45,133 --> 00:22:46,367 The overall look of these monuments 450 00:22:47,500 --> 00:22:49,367 is somewhat reminiscent of the monumental-stepped tombs 451 00:22:49,934 --> 00:22:51,266 found in ancient Egypt. 452 00:22:52,066 --> 00:22:53,166 When the team entered the towers, 453 00:22:54,266 --> 00:22:56,266 they discovered that they contained burial chambers, 454 00:22:56,834 --> 00:22:58,266 just like the pyramids. 455 00:22:59,467 --> 00:23:01,667 These stepped tombs have been deliberately built in groups 456 00:23:02,600 --> 00:23:04,300 to form an impressive ancient necropolis, 457 00:23:05,233 --> 00:23:06,767 a term that comes from the Greek "nekros," 458 00:23:07,834 --> 00:23:09,700 meaning "dead person," and "polis," meaning "city". 459 00:23:11,767 --> 00:23:14,600 In both ancient Greece and later in ancient Rome, 460 00:23:15,800 --> 00:23:17,900 necropolises would often line the roads leading in and out 461 00:23:18,700 --> 00:23:20,467 of major cities, dividing the living 462 00:23:20,900 --> 00:23:22,266 and the dead. 463 00:23:23,233 --> 00:23:24,400 We can see the same trend in ancient Egypt, 464 00:23:25,533 --> 00:23:27,367 where huge necropolises sit along the banks of the Nile, 465 00:23:28,533 --> 00:23:30,600 directly across from the cities they were associated with. 466 00:23:31,467 --> 00:23:32,800 The Al-Natah necropolis was built during 467 00:23:33,433 --> 00:23:35,200 the third millennium BCE. 468 00:23:36,233 --> 00:23:37,767 Most Greek and Egyptian necropolises built around 469 00:23:38,934 --> 00:23:41,166 the same time are associated with large cities that were 470 00:23:42,100 --> 00:23:43,867 home to thousands of permanent residents. 471 00:23:44,633 --> 00:23:45,467 But things were totally different 472 00:23:46,100 --> 00:23:46,867 on the Arabian Peninsula. 473 00:23:48,867 --> 00:23:52,567 Unlike ancient Rome, Greece or Egypt, this region was 474 00:23:53,633 --> 00:23:55,867 dominated by nomadic pastoralists who would travel 475 00:23:56,934 --> 00:23:58,900 across the peninsula with herds of grazing animals. 476 00:24:00,166 --> 00:24:02,667 Thousands of years ago, these groups developed 477 00:24:03,467 --> 00:24:04,767 their own unique burial traditions, 478 00:24:06,000 --> 00:24:08,567 constructing elaborate funerary avenues where their dead would 479 00:24:09,667 --> 00:24:12,567 be laid to rest under mounds of stones called cairns. 480 00:24:13,633 --> 00:24:15,767 But the monumental tombs at Al-Natah aren't anything 481 00:24:16,266 --> 00:24:17,467 like these graves. 482 00:24:19,767 --> 00:24:21,900 The enormous wall and elaborate necropolis 483 00:24:22,734 --> 00:24:24,967 at Al-Natah aren't at all consistent 484 00:24:25,533 --> 00:24:26,600 with nomadic traditions. 485 00:24:27,867 --> 00:24:31,166 Instead, both of these features point to a sedentary population, 486 00:24:32,233 --> 00:24:34,066 raising the possibility that a permanent settlement 487 00:24:34,567 --> 00:24:35,767 once existed here. 488 00:24:36,734 --> 00:24:38,567 Excavations in the eastern part of Al-Natah 489 00:24:39,433 --> 00:24:40,900 turned up thousands of pottery shards. 490 00:24:41,900 --> 00:24:43,300 Most of them were from simple bowls and jars, 491 00:24:44,233 --> 00:24:45,767 some of which were once used to store food. 492 00:24:46,934 --> 00:24:48,567 There were grinding stones, too, all of which would have 493 00:24:49,533 --> 00:24:52,166 been crucial for cooking during the Bronze Age. 494 00:24:53,100 --> 00:24:54,967 The pottery was associated with the remains 495 00:24:55,533 --> 00:24:56,367 of ancient buildings. 496 00:24:57,533 --> 00:25:00,066 Up to 70 of them once stood here, lining narrow streets 497 00:25:01,033 --> 00:25:03,000 that would have measured only six feet across. 498 00:25:04,033 --> 00:25:06,200 The amount of domestic kitchenware found tells us 499 00:25:07,300 --> 00:25:09,100 that these buildings were likely homes that made up 500 00:25:09,667 --> 00:25:11,100 a residential quarter. 501 00:25:12,500 --> 00:25:14,266 [Dr. Leonard] The existence of this extraordinary walled settlement 502 00:25:15,266 --> 00:25:17,100 tells us there were two competing ways of life 503 00:25:17,667 --> 00:25:19,000 being established here, 504 00:25:20,066 --> 00:25:22,266 a nomadic culture that traveled through the desert, 505 00:25:22,900 --> 00:25:24,066 and a sedentary population 506 00:25:24,934 --> 00:25:27,266 that decided to lay down permanent roots. 507 00:25:28,200 --> 00:25:30,266 History is filled with examples of clashes 508 00:25:31,133 --> 00:25:32,200 between sedentary and nomadic peoples, 509 00:25:32,900 --> 00:25:33,667 like during the Ming Dynasty, 510 00:25:34,734 --> 00:25:36,500 when the Great Wall of China was massively expanded 511 00:25:37,533 --> 00:25:39,500 to keep northern Steppe nomads from moving south. 512 00:25:40,533 --> 00:25:43,400 Based on the level of fortification at Al-Natah, 513 00:25:44,467 --> 00:25:46,000 it could be that the town also came into conflict 514 00:25:46,667 --> 00:25:47,800 with the surrounding nomads. 515 00:25:48,834 --> 00:25:49,867 But what could have caused these tensions between 516 00:25:51,066 --> 00:25:53,100 the nomadic and the settled way of life in the first place? 517 00:25:54,233 --> 00:25:57,467 A look back at ancient climate patterns may shed light 518 00:25:58,567 --> 00:26:00,266 on the origins of these extraordinary settlements. 519 00:26:01,166 --> 00:26:02,567 Humans have inhabited the Arabian desert 520 00:26:03,133 --> 00:26:04,066 for thousands of years. 521 00:26:05,066 --> 00:26:06,967 For a long time, the climate was relatively mild, 522 00:26:08,066 --> 00:26:10,300 and savanna-like grasslands spread over huge areas. 523 00:26:11,467 --> 00:26:15,266 But roughly 6,000 years ago, things changed dramatically. 524 00:26:15,867 --> 00:26:17,400 [Anthea] Around 4000 BCE, 525 00:26:18,367 --> 00:26:20,000 a phenomenon known as "rapid climate change" 526 00:26:20,934 --> 00:26:22,867 caused a massive decrease in precipitation 527 00:26:23,433 --> 00:26:24,600 across the peninsula. 528 00:26:25,800 --> 00:26:28,000 The environment transformed and left humans to figure out 529 00:26:28,500 --> 00:26:29,767 how best to adapt. 530 00:26:30,834 --> 00:26:32,867 Many continued to live nomadically, but over time, 531 00:26:33,433 --> 00:26:34,266 others chose to settle. 532 00:26:35,700 --> 00:26:38,266 During the Bronze Age, this region would have been 533 00:26:39,133 --> 00:26:41,166 greener than other areas of the desert, 534 00:26:42,166 --> 00:26:43,767 and would have seemed a natural place to build 535 00:26:44,266 --> 00:26:46,100 a permanent town. 536 00:26:46,633 --> 00:26:47,500 And it wasn't alone. 537 00:26:48,967 --> 00:26:52,667 Across Northwestern Arabia, several other oases reveal 538 00:26:53,834 --> 00:26:56,000 intriguing similarities to the settlement at Al-Natah. 539 00:26:57,467 --> 00:26:59,800 [Anthea] Qurayyah is a huge archaeological site 540 00:27:00,500 --> 00:27:03,000 stretching over 750 acres. 541 00:27:03,934 --> 00:27:05,400 The area is marked by a massive brick wall 542 00:27:06,300 --> 00:27:08,667 which once surrounded the entire oasis. 543 00:27:09,667 --> 00:27:12,000 Over time, a residential area also grew here, 544 00:27:12,700 --> 00:27:13,667 just like the one at Al-Natah. 545 00:27:15,266 --> 00:27:16,867 During the Bronze and Iron Ages, 546 00:27:17,734 --> 00:27:18,867 these settlements appeared around oases 547 00:27:19,533 --> 00:27:20,567 across Northwestern Arabia. 548 00:27:22,100 --> 00:27:23,867 Many of them were designed similarly, 549 00:27:24,433 --> 00:27:24,867 with internal ramparts 550 00:27:25,800 --> 00:27:26,867 dividing the various sections of the town, 551 00:27:27,867 --> 00:27:28,767 which were big enough to accommodate hundreds 552 00:27:29,333 --> 00:27:29,867 of permanent residents. 553 00:27:31,400 --> 00:27:34,800 The people who lived inside these walled oases built wells 554 00:27:35,834 --> 00:27:37,867 and intricate channels to collect surface water. 555 00:27:38,834 --> 00:27:40,000 They used the water to grow crops, orchards, 556 00:27:40,834 --> 00:27:41,700 and olive trees, as well as to support 557 00:27:42,266 --> 00:27:43,367 local craft production. 558 00:27:44,367 --> 00:27:46,400 These fortified towns flourished in large part 559 00:27:47,100 --> 00:27:48,467 due to their strategic location. 560 00:27:49,567 --> 00:27:52,300 Each town functioned as one node in an entire network, 561 00:27:53,300 --> 00:27:54,967 right at the intersection of the major powers 562 00:27:55,900 --> 00:27:58,166 of Egypt, the Levant, and Southern Arabia. 563 00:27:58,967 --> 00:28:00,100 A comparison of the walled oasis 564 00:28:01,333 --> 00:28:03,667 to other Bronze Age settlements shows an intriguing trend. 565 00:28:05,200 --> 00:28:07,700 The oasis settlements are thought to have supported 566 00:28:08,567 --> 00:28:10,100 a population of a few hundred people, 567 00:28:11,233 --> 00:28:12,767 which makes them much smaller than some of the cities 568 00:28:13,934 --> 00:28:16,467 growing around the same time, like the Egyptian capital, 569 00:28:17,734 --> 00:28:19,567 Memphis, which would have been home to thousands of residents. 570 00:28:21,266 --> 00:28:24,667 [Dr. Leonard] Despite being relatively small compared to major cities, 571 00:28:25,834 --> 00:28:27,266 these settlements represent a huge shift in the history 572 00:28:28,166 --> 00:28:30,867 the Arabian Peninsula, when slow urbanism 573 00:28:31,734 --> 00:28:32,367 radically changed the desert landscape 574 00:28:33,200 --> 00:28:35,066 over the course of hundreds of years. 575 00:28:36,133 --> 00:28:37,700 The settlement at Al-Natah seems to have persisted 576 00:28:38,633 --> 00:28:39,367 for roughly a millennium before the town was 577 00:28:39,934 --> 00:28:41,100 more or less abandoned. 578 00:28:41,900 --> 00:28:43,767 The reason why is still a mystery. 579 00:28:45,500 --> 00:28:49,000 Today, Al-Natah provides us with an invaluable glimpse 580 00:28:50,166 --> 00:28:52,367 into the past, where these extraordinary walled oases 581 00:28:53,467 --> 00:28:55,600 formed a bridge between the region's nomadic past 582 00:28:56,433 --> 00:28:59,200 and its increasingly urban future. 583 00:29:09,767 --> 00:29:13,367 Nestled in a remote corner of northwestern New Mexico, 584 00:29:14,400 --> 00:29:16,800 the Chaco Canyon carves its way through 10 miles 585 00:29:17,367 --> 00:29:19,166 of ancient sandstone. 586 00:29:20,200 --> 00:29:23,667 With an elevation of 6,200 feet, during the summer, 587 00:29:24,800 --> 00:29:27,467 Chaco Canyon is a sun-scorched desert with temperatures 588 00:29:28,433 --> 00:29:31,900 frequently reaching the mid-90s Fahrenheit. 589 00:29:32,900 --> 00:29:35,100 The winters are long and can get bitterly cold. 590 00:29:36,100 --> 00:29:38,266 And on top of that, the canyon only gets about 591 00:29:39,100 --> 00:29:40,467 two to five inches of rain per month. 592 00:29:41,467 --> 00:29:43,100 Despite the harsh conditions, there's evidence 593 00:29:44,367 --> 00:29:49,166 of human activity in the area going back as early as 2900 BCE. 594 00:29:50,300 --> 00:29:53,066 These groups were largely nomadic until around 200 AD, 595 00:29:53,967 --> 00:29:55,300 when the first farmers settled and built 596 00:29:55,800 --> 00:29:57,467 small pit houses. 597 00:29:58,433 --> 00:30:01,867 Then, around 850 CE, the Pueblo peoples began 598 00:30:02,900 --> 00:30:04,667 to build permanent homes and ceremonial structures 599 00:30:05,767 --> 00:30:08,567 in the area, and that changed the entire landscape. 600 00:30:09,467 --> 00:30:10,667 The Pueblo, who were the native ancestors 601 00:30:11,667 --> 00:30:13,567 of the Hopi and Acoma of today, among others, 602 00:30:14,567 --> 00:30:16,000 constructed massive stone and mortar buildings 603 00:30:17,133 --> 00:30:19,567 called greathouses, which soared to four or five stories 604 00:30:20,333 --> 00:30:21,867 and contained hundreds of rooms. 605 00:30:23,000 --> 00:30:25,066 Construction on the greathouses continued for 300 years, 606 00:30:26,200 --> 00:30:29,467 until about 1150, when the area was abruptly abandoned. 607 00:30:30,667 --> 00:30:32,600 Today, the Chaco Canyon is one of the most researched sites 608 00:30:33,166 --> 00:30:33,800 of the ancient Americas. 609 00:30:34,800 --> 00:30:36,400 The whole area is rich with cultural artifacts 610 00:30:37,066 --> 00:30:38,400 from early Pueblo settlers, 611 00:30:39,633 --> 00:30:42,367 and the walls of the canyon itself are embedded with fossils 612 00:30:43,300 --> 00:30:44,967 going back thousands of years before that. 613 00:30:46,967 --> 00:30:50,667 50 miles south of the canyon, a New Mexico gas company 614 00:30:51,934 --> 00:30:54,000 is collecting data for a future pipeline, working in tandem 615 00:30:55,000 --> 00:30:56,567 with a team of archaeologists, when they make 616 00:30:57,133 --> 00:30:58,367 an unusual discovery. 617 00:31:06,467 --> 00:31:10,100 50 miles south of the Chaco canyon, a New Mexico gas company 618 00:31:11,367 --> 00:31:13,800 is collecting data for a future pipeline, working in tandem 619 00:31:14,800 --> 00:31:16,400 with a team of archaeologists, when they make 620 00:31:16,967 --> 00:31:18,767 an unusual discovery. 621 00:31:19,800 --> 00:31:21,867 They identified a long segment of road extending 622 00:31:23,066 --> 00:31:27,367 from southeast to northwest in a perfectly straight line. 623 00:31:28,533 --> 00:31:31,200 The road was excavated directly into the sandstone bedrock 624 00:31:31,767 --> 00:31:33,667 for roughly 250 feet, 625 00:31:34,734 --> 00:31:36,667 at which point it entered the valley flats below, 626 00:31:37,567 --> 00:31:40,300 where all visible traces of it disappeared. 627 00:31:40,967 --> 00:31:42,667 But this was no modern road. 628 00:31:43,600 --> 00:31:46,500 Its origins went back roughly 1,000 years. 629 00:31:47,900 --> 00:31:50,667 [Teddy] Based on a nearby archaeological site featuring 630 00:31:51,633 --> 00:31:53,667 several Pueblo communities to the southeast. 631 00:31:54,633 --> 00:31:56,266 It was assumed the road was somehow connected 632 00:31:56,900 --> 00:31:58,300 to the Pueblo settlements. 633 00:31:59,367 --> 00:32:02,800 But its exact purpose and function was a mystery. 634 00:32:03,700 --> 00:32:04,166 [Dr. Leonard] Given that the greathouses 635 00:32:05,367 --> 00:32:07,100 required large amounts of heavy raw materials to build them, 636 00:32:08,300 --> 00:32:10,266 is it possible the ancient road was a former transport route 637 00:32:11,200 --> 00:32:12,166 for the construction of Pueblo settlements? 638 00:32:13,133 --> 00:32:15,000 The design principle behind the greathouses 639 00:32:15,934 --> 00:32:18,100 was a unique blend of form and function. 640 00:32:18,900 --> 00:32:20,100 They were geometric constructions 641 00:32:20,800 --> 00:32:22,567 made with careful craftsmanship, 642 00:32:23,433 --> 00:32:25,266 with walls of stone and adobe plaster 643 00:32:25,900 --> 00:32:27,300 covered with timber roofs. 644 00:32:28,467 --> 00:32:30,567 Now, those wooden roofs are long gone now, but the walls 645 00:32:31,734 --> 00:32:34,166 have done surprisingly well through the passage of time. 646 00:32:35,200 --> 00:32:37,800 The houses were feats of brilliant engineering, 647 00:32:38,700 --> 00:32:40,500 often including water collection systems, 648 00:32:41,433 --> 00:32:43,400 storage units, and sight lines that allowed 649 00:32:43,967 --> 00:32:45,166 for rapid communication. 650 00:32:46,900 --> 00:32:50,400 Entrances were generally south or southeast-facing, 651 00:32:51,467 --> 00:32:53,800 which provided shade from the summer sun and warmth 652 00:32:54,333 --> 00:32:55,467 from the winter sun. 653 00:32:56,600 --> 00:32:58,767 At the center of most complexes, there was an open plaza, 654 00:32:59,800 --> 00:33:02,066 which was believed to serve as a gathering space 655 00:33:02,900 --> 00:33:04,400 for communal and religious purposes. 656 00:33:05,800 --> 00:33:07,900 One of the best known greathouses 657 00:33:08,467 --> 00:33:09,767 was also the largest, 658 00:33:10,533 --> 00:33:12,367 located at the Pueblo Bonito site, 659 00:33:13,066 --> 00:33:15,000 also within the Chaco Canyon. 660 00:33:16,000 --> 00:33:20,300 It was built in stages between 850 and 1150 CE, 661 00:33:21,400 --> 00:33:22,900 with stone wall materials that had to be transported 662 00:33:23,333 --> 00:33:24,667 from off-site, 663 00:33:25,533 --> 00:33:27,567 and timber that came from a wooded area 664 00:33:28,567 --> 00:33:30,066 of ponderosa pines surrounding the settlement. 665 00:33:31,467 --> 00:33:33,300 [Dr. Leonard] In addition to the building foundations, 666 00:33:34,567 --> 00:33:37,000 archaeologists at Pueblo Bonito found traces of Mexican cacao 667 00:33:38,066 --> 00:33:40,066 and pottery shards imported from Central America, 668 00:33:40,633 --> 00:33:42,367 over 1200 miles away, 669 00:33:43,533 --> 00:33:45,867 likely intended as offerings for rituals and ceremonies. 670 00:33:46,767 --> 00:33:47,867 So it's possible the newly discovered road 671 00:33:48,900 --> 00:33:50,300 was used both as a pathway for building materials 672 00:33:50,867 --> 00:33:51,567 and as a trade route. 673 00:33:52,700 --> 00:33:55,900 But further examination of the ancient road presents 674 00:33:56,367 --> 00:33:57,600 a bigger puzzle. 675 00:33:58,767 --> 00:34:00,200 It was lined on the north side by a raised strip of land 676 00:34:01,166 --> 00:34:03,600 called a berm, created from fist-sized clumps 677 00:34:04,166 --> 00:34:05,467 of sandstone and earth. 678 00:34:06,467 --> 00:34:07,867 It was determined that the digging of the road 679 00:34:08,834 --> 00:34:09,667 into the sandstone, along with the creation 680 00:34:10,600 --> 00:34:11,800 of the elevated berms, would have required 681 00:34:12,834 --> 00:34:16,300 over 6,600 cubic feet of bedrock to be removed. 682 00:34:17,667 --> 00:34:20,667 This would have demanded a massive amount of labor, 683 00:34:21,533 --> 00:34:23,867 which indicated the road's importance. 684 00:34:25,000 --> 00:34:28,600 But the most baffling aspect of the road was its width. 685 00:34:29,400 --> 00:34:31,500 At over 20 feet across, it exceeded 686 00:34:32,333 --> 00:34:34,266 all practical necessity for a society 687 00:34:35,200 --> 00:34:39,000 with no wheeled vehicles and no pack animals. 688 00:34:39,867 --> 00:34:41,767 Put simply, this road was much bigger 689 00:34:42,867 --> 00:34:45,500 than it needed to be, especially if its only purpose 690 00:34:46,200 --> 00:34:47,600 was the transportation of goods. 691 00:34:48,567 --> 00:34:51,567 So is it possible it served another purpose? 692 00:34:52,567 --> 00:34:53,967 A deeper dive into the spiritual traditions 693 00:34:55,166 --> 00:34:58,266 of the Pueblo peoples reveals a compelling explanation. 694 00:34:59,700 --> 00:35:01,367 [Dr. Leonard] Pueblo Native Americans practiced the Kachina religion, 695 00:35:02,533 --> 00:35:04,567 a belief system that featured hundreds of divine beings 696 00:35:05,567 --> 00:35:06,967 acting as intermediaries between the human world, 697 00:35:08,000 --> 00:35:09,767 the gods, and the celestial world of astronomy. 698 00:35:12,000 --> 00:35:14,967 The religion was also at the center of civic life, 699 00:35:16,233 --> 00:35:19,000 as Pueblo villages were governed by Kachina religious councils. 700 00:35:20,300 --> 00:35:22,100 [Dr. Riskin] Spiritual practices didn't just impact daily life. 701 00:35:23,166 --> 00:35:25,266 Many Pueblo buildings and structures are believed 702 00:35:26,333 --> 00:35:28,567 to have been built with archaeo-astronomy in mind, 703 00:35:29,633 --> 00:35:31,467 which means they were built specifically to align 704 00:35:32,133 --> 00:35:33,600 with solar and lunar cycles. 705 00:35:34,500 --> 00:35:36,667 Entire villages were specifically planned 706 00:35:37,600 --> 00:35:39,166 with consideration of celestial alignments, 707 00:35:40,033 --> 00:35:42,266 like the sun's path during a solstice, 708 00:35:42,834 --> 00:35:44,367 or during an equinox. 709 00:35:45,400 --> 00:35:48,166 One of the most famous examples is the Sun Dagger, 710 00:35:49,233 --> 00:35:51,100 a Chaco Canyon discovery that was originally created 711 00:35:52,233 --> 00:35:56,266 to focus the sunlight onto an elaborate rock carving. 712 00:35:57,300 --> 00:36:00,100 Three large stone slabs were set against the cliff 713 00:36:01,233 --> 00:36:04,500 to channel the sun's rays onto two spiral petroglyphs, 714 00:36:05,266 --> 00:36:07,200 marking the solstices, equinoxes, 715 00:36:08,233 --> 00:36:12,467 and the lunar standstills of the 18.6-year cycle 716 00:36:12,867 --> 00:36:13,600 of the moon. 717 00:36:14,867 --> 00:36:17,667 It's believed these events formed the basis 718 00:36:18,633 --> 00:36:21,100 of important Pueblo rituals and ceremonies. 719 00:36:22,033 --> 00:36:23,900 Is it possible the ancient road was created 720 00:36:24,600 --> 00:36:26,367 for a similar celestial purpose? 721 00:36:34,600 --> 00:36:37,700 A survey of the surrounding area leads to a critical clue 722 00:36:38,800 --> 00:36:41,166 into the spiritual traditions of the Pueblo peoples. 723 00:36:42,400 --> 00:36:44,300 A large crescent-shaped wall of stacked stone was discovered 724 00:36:45,333 --> 00:36:47,467 on a flat section of earth adjacent to the road. 725 00:36:48,166 --> 00:36:49,467 Measuring 35 feet east to west 726 00:36:50,266 --> 00:36:52,667 and 46 feet across south to north, 727 00:36:53,433 --> 00:36:54,367 the round structure was created 728 00:36:55,200 --> 00:36:56,667 from fist-sized chunks of sandstone, 729 00:36:57,567 --> 00:36:59,000 connecting directly to the ancient road. 730 00:37:00,567 --> 00:37:03,166 The structure was identified as an "Herradura." 731 00:37:04,233 --> 00:37:05,667 That means horseshoe, and we've seen those before. 732 00:37:06,767 --> 00:37:09,000 They're essentially roadside shrines for the Pueblo, 733 00:37:10,233 --> 00:37:12,100 typically identified as such by their shape and by the shards 734 00:37:13,233 --> 00:37:15,767 of pottery and ceramics that are found in the vicinity. 735 00:37:16,834 --> 00:37:19,166 These are artifacts widely interpreted as offerings 736 00:37:19,567 --> 00:37:21,367 to the gods. 737 00:37:22,533 --> 00:37:25,367 The discovery of the Herradura roadside shrine definitely 738 00:37:26,333 --> 00:37:28,300 suggested the road was connected to some kind 739 00:37:29,533 --> 00:37:32,300 of ritual and that the landscape itself played an integral role 740 00:37:32,734 --> 00:37:33,867 in that ritual. 741 00:37:34,967 --> 00:37:37,166 However, up to that point, all the research was based 742 00:37:37,967 --> 00:37:39,000 on data collected at ground level, 743 00:37:39,800 --> 00:37:41,667 so any available evidence was limited 744 00:37:42,700 --> 00:37:44,567 to the road's physical properties and dimensions, 745 00:37:45,467 --> 00:37:46,467 what could only be seen by the naked eye. 746 00:37:47,700 --> 00:37:50,166 But the use of cutting-edge technology leads 747 00:37:50,700 --> 00:37:52,066 to a breakthrough. 748 00:37:53,166 --> 00:37:54,266 When the size and scale of the investigation increased 749 00:37:54,967 --> 00:37:56,266 to include entire landscapes, 750 00:37:57,367 --> 00:37:58,700 a decision was made to use an imaging process called 751 00:37:59,867 --> 00:38:03,100 "LiDAR," which stands for "light detection and ranging." 752 00:38:04,266 --> 00:38:06,467 It's a remote-sensing tech that creates digital 3D models 753 00:38:07,533 --> 00:38:08,867 of environments by measuring the relative distance 754 00:38:09,900 --> 00:38:11,667 of objects to the earth with pulsing laser light. 755 00:38:13,200 --> 00:38:15,000 [Dr. Riskin] For the road south of Chaco Canyon, 756 00:38:15,800 --> 00:38:17,567 a filter was applied to the images 757 00:38:18,467 --> 00:38:19,767 that made it look like light was coming 758 00:38:20,600 --> 00:38:21,667 from different angles and altitudes. 759 00:38:22,934 --> 00:38:25,400 And what emerges from that is this 3D picture of the landscape 760 00:38:26,467 --> 00:38:29,200 that exaggerates anomalies, making things visible 761 00:38:30,133 --> 00:38:32,767 to the human eye that normally would not be. 762 00:38:33,533 --> 00:38:35,166 The LiDAR images deliver not one, 763 00:38:35,900 --> 00:38:38,100 but two surprising revelations. 764 00:38:39,066 --> 00:38:41,000 First, the data showed that the ancient road 765 00:38:42,133 --> 00:38:45,000 extended for at least another three and a half miles. 766 00:38:46,367 --> 00:38:48,567 It continued in a straight line, 767 00:38:49,367 --> 00:38:50,700 regardless of where the road led, 768 00:38:51,233 --> 00:38:52,567 over earthen ramps, 769 00:38:53,467 --> 00:38:55,667 descending into valleys, even incorporating 770 00:38:56,633 --> 00:39:00,467 man-made staircases cut right into the rock. 771 00:39:01,567 --> 00:39:03,567 Even more shocking, the LiDAR revealed the presence 772 00:39:04,667 --> 00:39:07,500 of a second straight road, parallel to the first one 773 00:39:08,367 --> 00:39:11,567 and about 115 feet directly southwest. 774 00:39:12,433 --> 00:39:13,900 The second road also displayed evidence 775 00:39:14,600 --> 00:39:16,567 of an Herradura roadside shrine, 776 00:39:17,467 --> 00:39:19,266 and it too was uncharacteristically wide, 777 00:39:20,033 --> 00:39:21,266 measuring almost 20 feet across. 778 00:39:23,667 --> 00:39:26,066 Initially, the two roads appeared to run 779 00:39:26,834 --> 00:39:27,767 perfectly parallel to each other. 780 00:39:28,934 --> 00:39:32,166 However, a closer look revealed they slowly came together 781 00:39:32,834 --> 00:39:33,467 to a point in the distance. 782 00:39:35,000 --> 00:39:37,266 At the near end, the widest space between 783 00:39:38,100 --> 00:39:40,066 the two roads was roughly 120 feet. 784 00:39:41,033 --> 00:39:42,500 From that point, the roads seemed to converge, 785 00:39:43,533 --> 00:39:45,100 measuring just 50 feet across at its most narrow. 786 00:39:46,600 --> 00:39:49,667 An enormous amount of effort went into the planning 787 00:39:50,333 --> 00:39:51,567 and building of both roads. 788 00:39:52,633 --> 00:39:55,867 So given the Pueblo emphasis on sacred topography, 789 00:39:56,800 --> 00:39:58,467 plus the significance of celestial events 790 00:39:58,967 --> 00:39:59,700 in their calendar, 791 00:40:00,500 --> 00:40:02,567 is it possible that these two roads 792 00:40:03,700 --> 00:40:05,800 were pointing towards an important spiritual landmark 793 00:40:06,233 --> 00:40:06,967 on the horizon? 794 00:40:09,100 --> 00:40:12,700 A survey of the surrounding area provides the answer. 795 00:40:13,767 --> 00:40:16,567 From the perspective of the first Herradura Shrine, 796 00:40:17,600 --> 00:40:21,100 as well as various points along the second road, 797 00:40:22,000 --> 00:40:24,266 both roads form a clear visual trajectory 798 00:40:24,900 --> 00:40:26,467 towards a single landmass 799 00:40:27,300 --> 00:40:30,066 directly southeast -- Mount Taylor. 800 00:40:31,467 --> 00:40:34,900 And Mount Taylor is an eminently sacred mountain 801 00:40:35,700 --> 00:40:37,467 among contemporary Pueblo and Diné 802 00:40:38,266 --> 00:40:40,166 living in northwestern New Mexico. 803 00:40:41,367 --> 00:40:43,600 The survey also indicated that both roads ran at an azimuth 804 00:40:44,700 --> 00:40:47,100 of approximately 120 degrees and that the second road 805 00:40:48,200 --> 00:40:49,700 corresponded with the position of the winter solstice 806 00:40:50,367 --> 00:40:51,667 at the original Gasco site. 807 00:40:53,033 --> 00:40:54,667 [Dr. Riskin] As the shortest day of the year and the longest night, 808 00:40:55,800 --> 00:40:58,100 winter solstice marks the point at which the sun reaches 809 00:40:59,233 --> 00:41:01,567 the most southerly position in the sky over the course 810 00:41:02,233 --> 00:41:03,867 of its entire annual cycle. 811 00:41:05,133 --> 00:41:07,400 Suspecting the sun would rise over Mount Taylor in alignment 812 00:41:08,367 --> 00:41:09,867 with both roads during the winter solstice, 813 00:41:10,900 --> 00:41:12,567 researchers returned to the site on the morning 814 00:41:13,066 --> 00:41:14,367 of December 21st. 815 00:41:15,133 --> 00:41:17,467 As anticipated and as if on cue, 816 00:41:18,433 --> 00:41:20,000 the sun rose dramatically over the mountain 817 00:41:21,033 --> 00:41:23,000 in perfect alignment with the two road corridors 818 00:41:24,000 --> 00:41:27,066 when is viewed from the center of the roadbed. 819 00:41:28,033 --> 00:41:30,066 For the Pueblo peoples, the awe-inspiring view 820 00:41:30,900 --> 00:41:32,667 of the sun rising over Mount Taylor 821 00:41:33,633 --> 00:41:35,467 likely symbolized the powerful relationship 822 00:41:36,000 --> 00:41:36,867 between the natural 823 00:41:37,834 --> 00:41:40,300 and spiritual worlds and exemplifies the role 824 00:41:41,467 --> 00:41:43,867 the celestial calendar played in guiding religious life. 825 00:41:45,700 --> 00:41:47,000 The ancient roads 826 00:41:47,934 --> 00:41:49,266 of the Chaco Canyon reveal the Pueblo 827 00:41:50,300 --> 00:41:52,000 to have been masters at imbuing urban planning 828 00:41:52,867 --> 00:41:54,400 with a deep connection to the sacred 829 00:41:55,300 --> 00:41:56,967 and a keen understanding of cosmology.
