1 00:00:17,760 --> 00:00:20,760 Today marks a special moment in the Mayan calendar. 2 00:00:21,440 --> 00:00:24,680 It's the spring equinox when the sunrise ushers in 3 00:00:24,760 --> 00:00:27,800 not just a new day but a new cycle of life. 4 00:00:31,200 --> 00:00:33,000 As the sun clears the tree line, 5 00:00:34,040 --> 00:00:37,520 its rays illuminate one of Palenque's most majestic temples. 6 00:00:40,800 --> 00:00:44,240 This is the Temple of the Sun, a most appropriate name. 7 00:00:45,560 --> 00:00:49,120 Just to be here, bathed in light, is a privilege, 8 00:00:49,200 --> 00:00:52,840 a connection that merges spirituality with science in a way 9 00:00:52,920 --> 00:00:54,960 long forgotten by the modern world. 10 00:00:57,280 --> 00:01:00,600 At certain key moments of the year, and this is one of them, 11 00:01:01,400 --> 00:01:05,000 the rising sun does more than illuminate the steps of the temple. 12 00:01:06,240 --> 00:01:09,760 Maya architecture is a repository for ancient knowledge, 13 00:01:10,280 --> 00:01:12,880 linking sky and ground, heaven and earth. 14 00:01:15,560 --> 00:01:18,000 In the process, it often brought the light of the sun 15 00:01:18,080 --> 00:01:21,520 through certain specific alignments into interior spaces, 16 00:01:21,600 --> 00:01:23,720 purposefully designed to receive it. 17 00:01:25,560 --> 00:01:29,680 At the winter solstice, the sun rises over a mountaintop ruin, 18 00:01:30,960 --> 00:01:33,280 shining into the temple through a doorway, 19 00:01:33,360 --> 00:01:37,320 where we might imagine a priest waiting to be bathed in light. 20 00:01:38,520 --> 00:01:41,760 Six months later, on the summer solstice, 21 00:01:42,400 --> 00:01:47,040 and only on that day, the dawn sunlight grazes another pyramid, 22 00:01:47,120 --> 00:01:49,960 before a needle of light strikes an interior corner, 23 00:01:52,400 --> 00:01:56,920 while at both equinoxes, the sun rises above a man-made depression 24 00:01:57,000 --> 00:02:00,840 in the eastern horizon, again shining rays through a doorway 25 00:02:02,240 --> 00:02:06,000 at such a precise angle, that for around 40 minutes, 26 00:02:06,080 --> 00:02:09,200 it dramatically illuminates another inner alcove. 27 00:02:16,360 --> 00:02:20,640 For the Maya, such dazzling displays must have evoked a sense of awe 28 00:02:20,720 --> 00:02:22,240 in all who observed them. 29 00:02:25,640 --> 00:02:28,680 And it's not just a special moment for the ancient Maya. 30 00:02:37,880 --> 00:02:41,840 Palenque is an extremely symbolic site. 31 00:02:43,520 --> 00:02:47,320 {\an8}Ancestral worship in Palenque was depicted in its architecture 32 00:02:47,400 --> 00:02:49,880 {\an8}and in its modified landscape. 33 00:02:51,080 --> 00:02:53,640 It connects with the modern-day population. 34 00:02:56,000 --> 00:03:00,360 Mayan culture in Palenque is very much alive. 35 00:03:03,880 --> 00:03:06,240 {\an8} Maya priest Nicolás López Vázquez 36 00:03:06,320 --> 00:03:09,560 {\an8}has been performing ceremonies here for decades. 37 00:03:12,920 --> 00:03:18,960 The ritual going on right now represents the spring equinox. 38 00:03:19,640 --> 00:03:22,360 The equinox was very important. 39 00:03:23,560 --> 00:03:25,760 That's why they made the temples. 40 00:03:26,480 --> 00:03:29,920 It is like a connection with the whole planet. 41 00:03:34,240 --> 00:03:37,200 Indeed, this complex seems to have been designed 42 00:03:37,280 --> 00:03:42,480 as an instrument to detect and manifest the wondrous harmony of the universe. 43 00:03:51,320 --> 00:03:54,760 So what was the motive for their intense focus on the heavens? 44 00:03:54,840 --> 00:03:58,320 And how did they acquire their advanced astronomical know-how? 45 00:04:01,240 --> 00:04:06,560 Could we be witnessing a legacy handed down by a far older civilization, 46 00:04:08,440 --> 00:04:11,080 one that left traces of its advanced knowledge 47 00:04:11,160 --> 00:04:12,440 throughout the Americas? 48 00:04:29,880 --> 00:04:32,760 {\an8}- 49 00:04:41,080 --> 00:04:46,360 Dominating the center of Palenque is its most impressive edifice 50 00:04:47,600 --> 00:04:48,960 known as the palace. 51 00:04:52,240 --> 00:04:55,520 And above it looms this intriguing structure, 52 00:04:56,240 --> 00:05:00,080 unique in the Maya world, a multi-storied tower. 53 00:05:02,800 --> 00:05:06,080 Scholars are divided on the purpose of this tower. 54 00:05:06,680 --> 00:05:08,440 The puzzling thing is the roof. 55 00:05:09,240 --> 00:05:12,400 The roof we see today is an entirely modern 56 00:05:12,480 --> 00:05:15,280 and possibly inaccurate reconstruction. 57 00:05:16,480 --> 00:05:20,600 Earlier excavation photographs show the tower in ruins without a roof. 58 00:05:21,600 --> 00:05:23,840 So was it roofed in antiquity? 59 00:05:25,480 --> 00:05:29,840 Indeed, the original tower may have been topped by an observation platform, 60 00:05:30,640 --> 00:05:32,680 which would explain what was found within. 61 00:05:34,600 --> 00:05:37,200 It's significant that there's a room with glyphs 62 00:05:37,280 --> 00:05:42,800 representing perhaps the most important of all planets to the Maya, Venus. 63 00:05:44,880 --> 00:05:47,680 Scholars have confirmed through Mayan texts 64 00:05:48,360 --> 00:05:52,840 that this symbol does indeed represent the brightest planet in the night sky. 65 00:05:54,960 --> 00:06:00,040 Could it be that this tower was built specifically for use by astronomers? 66 00:06:02,480 --> 00:06:07,080 Intuitively, it feels like it was intended for observations of the heavens. 67 00:06:07,160 --> 00:06:12,400 One would not expect a tower designed to observe the skies 68 00:06:12,480 --> 00:06:14,240 to be roofed. 69 00:06:14,320 --> 00:06:17,640 And those Venus glyphs inside the tower 70 00:06:17,720 --> 00:06:20,200 strongly suggest that that's what it was used for. 71 00:06:21,240 --> 00:06:25,240 But of all the celestial bodies in the sky, why Venus? 72 00:06:27,360 --> 00:06:32,160 It may have something to do with one of the Maya's greatest mythological figures. 73 00:06:36,280 --> 00:06:41,640 The gods and goddesses of Maya cosmology often had eerily human characteristics, 74 00:06:41,720 --> 00:06:45,760 sometimes endearing, sometimes terrifying, 75 00:06:45,840 --> 00:06:48,160 sometimes deeply mysterious. 76 00:06:48,680 --> 00:06:52,960 The deity named Kukulkan, who was at one time a man, 77 00:06:53,040 --> 00:06:55,640 not only combined all of these characteristics, 78 00:06:55,720 --> 00:06:59,320 but was also identified with the brightest planet in the heavens. 79 00:07:02,960 --> 00:07:07,880 The tradition says that Kukulkan arrived after a great cataclysm, 80 00:07:08,520 --> 00:07:10,080 accompanied by attendants. 81 00:07:11,440 --> 00:07:15,720 He was a wise teacher who gave instruction in the rule of law 82 00:07:16,320 --> 00:07:20,520 and how to organize a civilization, to cultivate corn, 83 00:07:21,440 --> 00:07:23,920 and how to build great monuments in stone. 84 00:07:25,240 --> 00:07:27,560 Even after his time with them was over, 85 00:07:28,400 --> 00:07:31,360 Kukulkan continued to be worshiped in the heavens, 86 00:07:31,880 --> 00:07:36,640 where he manifested in the form of the planet that we know today as Venus. 87 00:07:42,760 --> 00:07:44,520 Across the Maya world, 88 00:07:44,600 --> 00:07:47,160 there are other representations of Kukulkan. 89 00:07:47,880 --> 00:07:51,640 {\an8}And at one iconic site, his memory is also connected 90 00:07:51,720 --> 00:07:55,680 {\an8}to that highly significant moment of the spring equinox. 91 00:07:56,480 --> 00:08:00,800 At Chichén Itzá in the Yucatán, at the temple of Kukulkan, 92 00:08:00,880 --> 00:08:04,080 if we look at that pyramid, what we see normally 93 00:08:04,160 --> 00:08:08,200 is the northern stairway of the pyramid with the large head of a serpent 94 00:08:08,280 --> 00:08:12,680 at the base of the stairway and a kind of blank balustrade 95 00:08:12,760 --> 00:08:14,640 running up the side of it with nothing on it, 96 00:08:14,720 --> 00:08:18,560 but on the spring equinox, as the sun is beginning to set, 97 00:08:19,480 --> 00:08:24,520 the pyramid is so perfectly positioned that shadows cast by its corner 98 00:08:24,600 --> 00:08:28,640 onto that stairway create the form of the body of the serpent, 99 00:08:28,720 --> 00:08:31,840 so the head of the serpent is suddenly completed with 100 00:08:31,920 --> 00:08:35,960 an undulating, waving shadow body of the serpent, 101 00:08:36,040 --> 00:08:38,840 and this is a manifestation of Kukulkan. 102 00:08:42,640 --> 00:08:46,040 In different parts of Mexico, he was known not only as Kukulkan 103 00:08:46,600 --> 00:08:49,360 but perhaps most famously as Quetzalcoatl. 104 00:08:50,080 --> 00:08:53,800 All of these names mean "plumed or feathered serpent." 105 00:08:54,840 --> 00:08:58,240 One might almost imagine that Kukulkan was a traveler 106 00:08:58,320 --> 00:09:01,480 who used a locally-appropriate name wherever he went. 107 00:09:03,560 --> 00:09:08,040 We've met a similar figure in Peru where he was called Viracocha. 108 00:09:09,080 --> 00:09:12,080 In Mesopotamia, he was known as Oannes, 109 00:09:12,160 --> 00:09:14,320 and in Egypt, he was Osiris. 110 00:09:15,680 --> 00:09:17,400 But the stories remain the same. 111 00:09:19,080 --> 00:09:22,400 Powerful figures who appeared after a global cataclysm 112 00:09:23,360 --> 00:09:26,960 and bestowed upon ancient peoples the gifts of civilization. 113 00:09:30,680 --> 00:09:34,480 The identification of their civilizing hero with the planet Venus 114 00:09:35,120 --> 00:09:38,360 might explain one of the Maya's unique obsessions, 115 00:09:39,120 --> 00:09:41,600 tracking that planet's movements in the night sky. 116 00:09:43,400 --> 00:09:47,400 Their studies of Venus are really, really striking. 117 00:09:47,480 --> 00:09:51,280 It is the case that once every roughly 584 days, 118 00:09:51,360 --> 00:09:53,840 Venus will be seen to rise in the same place. 119 00:09:53,920 --> 00:09:58,760 The Maya had an absolutely precise, spot-on estimate 120 00:09:58,840 --> 00:10:01,760 of the… what's called the synodical return of Venus. 121 00:10:02,840 --> 00:10:05,160 And they were able to make the calculation 122 00:10:05,240 --> 00:10:08,360 thanks to one of the Maya's most extraordinary achievements, 123 00:10:09,240 --> 00:10:12,560 one that, like the incredible stonework of ancient Peru 124 00:10:13,080 --> 00:10:15,480 and the ingenious pharmacology of ancient Amazonia, 125 00:10:17,560 --> 00:10:22,320 might be part of a legacy of knowledge handed down from a remote prehistory 126 00:10:22,400 --> 00:10:24,920 by a mysterious predecessor civilization. 127 00:10:35,960 --> 00:10:39,200 {\an8}Dr. Edwin Barnhart has been mapping and studying Palenque 128 00:10:39,280 --> 00:10:41,000 for over 25 years, 129 00:10:42,920 --> 00:10:45,480 and he's one of very few people in the world 130 00:10:46,000 --> 00:10:48,360 who can read the script of the ancient Maya. 131 00:10:51,960 --> 00:10:56,120 We read these glyphs from top to bottom in double columns. 132 00:10:56,200 --> 00:10:59,640 You read right left, right left to the bottom of the first two, 133 00:10:59,720 --> 00:11:03,520 and then you go to the third and fourth and read down so that's the reading order. 134 00:11:03,600 --> 00:11:06,920 How does the system of numbers that the Maya use 135 00:11:07,000 --> 00:11:10,240 compare with the system of numbers that we use today? 136 00:11:10,320 --> 00:11:12,120 Our system is quite similar. 137 00:11:12,200 --> 00:11:14,960 We have a base-ten system. We call it decimal. 138 00:11:15,040 --> 00:11:18,800 You and I, we can write any number 139 00:11:19,520 --> 00:11:23,240 - into almost infinity using ten digits. - Mm-hmm. 140 00:11:23,320 --> 00:11:26,200 We've got a zero, and then one through nine. 141 00:11:26,280 --> 00:11:28,560 - Yeah. - And when we get to ten, 142 00:11:28,640 --> 00:11:31,640 we put a zero in the ones place and a one in the tens place. 143 00:11:31,720 --> 00:11:33,840 They use base 20. 144 00:11:36,680 --> 00:11:39,360 It's a Morse code-like system of dashes and dots 145 00:11:40,480 --> 00:11:43,040 including a shell glyph representing zero. 146 00:11:45,040 --> 00:11:46,520 A dot means one. 147 00:11:46,600 --> 00:11:48,400 - A bar means five. - Right. 148 00:11:49,280 --> 00:11:52,440 And so when you get three bars and four dots, 149 00:11:52,520 --> 00:11:54,200 - that's 19. - Mm-hmm. 150 00:11:55,120 --> 00:11:57,400 How they'd write 20 is putting a zero there 151 00:11:58,000 --> 00:12:00,320 - and then putting a dot in the 20 place. - Okay. 152 00:12:00,920 --> 00:12:04,480 So it's a positional system of enumeration that allowed them 153 00:12:04,560 --> 00:12:06,440 to do math on a… on a different level. 154 00:12:07,760 --> 00:12:09,560 You know, our system's great. 155 00:12:09,640 --> 00:12:14,640 We can calculate into infinity, but it takes ten symbols. 156 00:12:14,720 --> 00:12:17,560 The Maya pulled the same thing off with only three symbols. 157 00:12:17,640 --> 00:12:19,200 So in that regard, 158 00:12:19,800 --> 00:12:21,960 their system is way more elegant than ours. 159 00:12:22,040 --> 00:12:23,360 Wow. 160 00:12:25,760 --> 00:12:27,840 The Maya not only used zero, 161 00:12:28,440 --> 00:12:30,440 but were acquainted with place numerations 162 00:12:31,440 --> 00:12:33,880 at a time when the Ancient Greeks and Romans, 163 00:12:33,960 --> 00:12:37,240 despite their many achievements, understood neither. 164 00:12:39,360 --> 00:12:42,240 Their system was great. The Romans, they did great things, 165 00:12:42,320 --> 00:12:43,880 but their number system stunk. 166 00:12:43,960 --> 00:12:45,800 - That's why they had to make the abacus. - Yeah. 167 00:12:47,800 --> 00:12:49,840 The Maya's advanced numbering system 168 00:12:49,920 --> 00:12:52,000 wasn't just an elegant way to count. 169 00:12:52,600 --> 00:12:53,960 For their astronomers, 170 00:12:54,040 --> 00:12:57,080 this was the key to calculating and predicting the movements 171 00:12:57,160 --> 00:13:01,000 of heavenly bodies like Venus, the sun, and the moon, 172 00:13:01,080 --> 00:13:02,760 with astounding accuracy. 173 00:13:03,800 --> 00:13:07,800 And that same knowledge of mathematics was also fundamental 174 00:13:07,880 --> 00:13:10,960 to what was arguably their most impressive invention. 175 00:13:11,840 --> 00:13:15,160 By far the most perplexing achievement of the ancient Maya 176 00:13:15,240 --> 00:13:19,000 was their own amazingly precise system for measuring time, 177 00:13:19,520 --> 00:13:22,840 which they incorporated into one of the most complex calendars 178 00:13:22,920 --> 00:13:24,000 in human history. 179 00:13:26,560 --> 00:13:29,440 The calendar, which of course is incredibly complicated. 180 00:13:30,040 --> 00:13:34,080 Could you help to uncomplicate it for me? What is the Mayan calendar all about? 181 00:13:34,160 --> 00:13:38,880 The calendar, its… You know, its solar year is 365 days. 182 00:13:38,960 --> 00:13:39,920 Right. Okay. 183 00:13:40,000 --> 00:13:43,960 The calendar they really care about is 260 days, 184 00:13:44,040 --> 00:13:48,440 but then they have a long count calendar, which is kind of a linear count of time. 185 00:13:51,040 --> 00:13:55,320 The Maya tracked key dates using a combination of three calendars, 186 00:13:56,040 --> 00:13:58,320 each with its own individual purpose. 187 00:13:59,760 --> 00:14:00,840 {\an8} 188 00:14:00,920 --> 00:14:05,320 {\an8}Their sacred calendar was a repeating cycle of 20 groups 189 00:14:05,400 --> 00:14:10,120 {\an8}consisting of 13 days apiece, totaling 260 days. 190 00:14:10,200 --> 00:14:11,560 {\an8} 191 00:14:11,640 --> 00:14:14,120 {\an8}A second calendar tracked the solar year, 192 00:14:14,720 --> 00:14:18,120 {\an8}but was composed of 18 groups, each of 20 days, 193 00:14:18,840 --> 00:14:23,400 {\an8}with another five to complete a 365-day year, just like ours. 194 00:14:24,880 --> 00:14:26,320 {\an8}When used in tandem, 195 00:14:26,400 --> 00:14:30,760 these two calendars gave a unique name to every single day 196 00:14:31,320 --> 00:14:35,600 across a 52-year period before then starting over. 197 00:14:38,040 --> 00:14:42,720 But what made the Mayan system truly unique was their third calendar, 198 00:14:43,240 --> 00:14:44,800 the so-called long count, 199 00:14:45,360 --> 00:14:47,680 which tracked much greater periods of time. 200 00:14:50,000 --> 00:14:52,400 Tell me more about the long count calendar. 201 00:14:52,480 --> 00:14:54,960 What is it? How does it work? 202 00:14:55,680 --> 00:14:57,600 What's it intended to achieve? 203 00:14:58,120 --> 00:15:01,600 It's certainly the most interesting one because the Maya are very cyclical, 204 00:15:01,680 --> 00:15:05,000 but it's the only calendar they have that's a linear calendar. 205 00:15:05,080 --> 00:15:10,560 It can go backwards and forwards in time in a straight line into, towards infinity. 206 00:15:11,240 --> 00:15:14,160 The symbols of the long count measure the passage 207 00:15:14,240 --> 00:15:19,920 not just of years, decades, or centuries, but entire millennia, 208 00:15:20,000 --> 00:15:22,880 reaching deep into both the past and the future. 209 00:15:23,720 --> 00:15:28,600 Is it the case that most of what we can now read in the… in the Maya script 210 00:15:28,680 --> 00:15:29,960 has to do with the calendar? 211 00:15:30,040 --> 00:15:33,840 Here's a perfect example that when we look at this page, 212 00:15:34,440 --> 00:15:38,080 everything that you see with bars and dots and these, 213 00:15:38,160 --> 00:15:40,480 this is all calendrical information. 214 00:15:41,200 --> 00:15:42,120 On the whole, 215 00:15:42,200 --> 00:15:47,280 two-thirds of the entire Maya corpus of writing are calendar glyphs. 216 00:15:49,320 --> 00:15:51,480 One explanation for this obsession 217 00:15:51,560 --> 00:15:55,320 is that the ancient Maya believed the world went through recurring cycles 218 00:15:55,400 --> 00:15:57,400 of creation and destruction… 219 00:16:03,160 --> 00:16:05,480 …and that they were living in the fourth such cycle, 220 00:16:08,360 --> 00:16:10,560 quite similar to the ancient Hopi 221 00:16:10,640 --> 00:16:13,200 who believed they too were living in the fourth world. 222 00:16:14,040 --> 00:16:15,080 But unlike them, 223 00:16:15,160 --> 00:16:18,520 the Maya were able to put specific dates to their cycles, 224 00:16:19,720 --> 00:16:21,680 all tracked using the long count. 225 00:16:24,160 --> 00:16:26,000 What's this one about here? 226 00:16:26,520 --> 00:16:28,640 That's a beautiful image, 227 00:16:28,720 --> 00:16:32,240 one of the few that very specifically tells us 228 00:16:32,320 --> 00:16:35,600 what the date was at the start of the fourth creation. 229 00:16:36,120 --> 00:16:41,200 - It says 13-0-0-0-0. - Right. 230 00:16:41,800 --> 00:16:47,760 And then the very next day, this resets. And this would be 0-0-0-0-1. 231 00:16:47,840 --> 00:16:51,520 Right. So putting that into our dating system today? 232 00:16:51,600 --> 00:16:56,600 - 3114 B.C., August 13th. - Right. 233 00:16:56,680 --> 00:16:59,760 And that's the beginning of the age of the world in which we now live. 234 00:16:59,840 --> 00:17:02,000 Right. And the idea, like, 235 00:17:02,720 --> 00:17:08,360 - why did it start at 3114 B.C.? - Yeah. 236 00:17:08,440 --> 00:17:12,080 That's one that the best minds, for a century now… 237 00:17:12,160 --> 00:17:14,560 - Yeah. - …have failed to sufficiently answer. 238 00:17:14,640 --> 00:17:19,000 Yeah. I… I have to say, I find that date quite fascinating in itself, 239 00:17:19,080 --> 00:17:24,120 um, since many ancient civilizations, if we follow the archaeological record, 240 00:17:24,200 --> 00:17:26,360 had an extraordinary beginning at around that time. 241 00:17:28,560 --> 00:17:30,680 {\an8}In Ancient Egypt around 3000 B.C. 242 00:17:30,760 --> 00:17:34,520 {\an8}- Sumer, similar sort of period. Right. Asia as well. 243 00:17:35,440 --> 00:17:37,640 {\an8}It's like the world was waking up at that time, 244 00:17:37,720 --> 00:17:39,440 and the Maya picked that date. 245 00:17:39,520 --> 00:17:40,560 It is very interesting. 246 00:17:42,680 --> 00:17:44,560 When do you think the system began? 247 00:17:45,080 --> 00:17:49,000 How far back can we trace the origins of this incredible set of calculations? 248 00:17:49,080 --> 00:17:51,920 You know, it's a difficult question. I've pondered that a lot. 249 00:17:52,000 --> 00:17:56,400 And I… I like to say that by the time somebody carved it in stone, 250 00:17:57,440 --> 00:17:58,920 that wasn't their first attempt. 251 00:17:59,000 --> 00:18:02,320 Right. And what's the oldest date that you… that you've found? 252 00:18:02,400 --> 00:18:05,600 There's a couple of them. There's one that goes back 33,000 years. 253 00:18:06,200 --> 00:18:09,840 Another leads us to a specific date 254 00:18:09,920 --> 00:18:13,560 that has us go back very exactly five million years. 255 00:18:13,640 --> 00:18:17,560 - Five million years into the past. - Yeah. And… and you can do the math. 256 00:18:19,080 --> 00:18:23,840 I think that its intention is to make a statement 257 00:18:23,920 --> 00:18:26,280 about the never-ending nature of time. 258 00:18:29,160 --> 00:18:30,720 Alongside these dates, 259 00:18:30,800 --> 00:18:33,360 one key player in the drama of the night sky 260 00:18:33,440 --> 00:18:36,320 keeps appearing in the texts, Venus, 261 00:18:36,960 --> 00:18:41,080 that same planet associated with the Mayan deity, Kukulkan. 262 00:18:44,920 --> 00:18:50,240 So Venus is integrated into the overall Mayan calendrical system. 263 00:18:50,320 --> 00:18:51,760 They track it again and again. 264 00:18:51,840 --> 00:18:55,520 There's actually 104 different groups 265 00:18:55,600 --> 00:18:58,480 - of five Venus cycles… - Yeah. 266 00:18:58,560 --> 00:19:01,280 …that they put together so that you could actually track Venus 267 00:19:01,360 --> 00:19:03,040 - and it would be right. - Right. 268 00:19:04,480 --> 00:19:09,200 The Maya were obsessed with the cosmos, and the Maya were obsessed with time. 269 00:19:10,080 --> 00:19:13,560 These two issues are fundamental to… to Mayan culture. 270 00:19:16,200 --> 00:19:20,680 These two obsessions reveal that the Maya had and enumerated 271 00:19:20,760 --> 00:19:24,080 a deep understanding of our planet's vast antiquity. 272 00:19:26,120 --> 00:19:29,960 So they were able to do what modern computer software is doing. 273 00:19:30,480 --> 00:19:31,840 - Yes. - How could they do that? 274 00:19:32,880 --> 00:19:34,840 I think that they were among 275 00:19:34,920 --> 00:19:37,360 the ancient world's greatest mathematicians. 276 00:19:37,440 --> 00:19:39,680 - They just kept cranking the numbers. - Yeah. 277 00:19:39,760 --> 00:19:42,480 They're doing calculations of millions of days. 278 00:19:42,560 --> 00:19:43,640 Fascinating. 279 00:19:45,160 --> 00:19:48,120 If they're using dates like that, you have to ask yourself, 280 00:19:48,200 --> 00:19:50,160 "Why would they need to do that?" 281 00:19:51,200 --> 00:19:53,440 - I think-- - It's all speculation. 282 00:19:53,520 --> 00:19:56,200 When we archaeologists take a hard look in the mirror, 283 00:19:56,280 --> 00:19:58,320 - basically it's all speculation. We-- - Yeah. 284 00:19:58,400 --> 00:20:01,240 We are working on theories. Very few facts in my field. 285 00:20:01,320 --> 00:20:02,160 Yeah. 286 00:20:06,800 --> 00:20:11,200 I have a theory, which is also, admittedly, speculative. 287 00:20:13,160 --> 00:20:16,480 The Mayan calendar feels to me like an out-of-place artifact. 288 00:20:17,000 --> 00:20:20,640 It feels to me like a legacy that the Maya have received 289 00:20:20,720 --> 00:20:24,040 from a culture that really did need these enormous numbers… 290 00:20:25,880 --> 00:20:28,840 A lost civilization that passed on its knowledge 291 00:20:28,920 --> 00:20:30,920 of the cyclical nature of time, 292 00:20:31,760 --> 00:20:34,360 encoding it in myths and spiritual traditions 293 00:20:35,400 --> 00:20:38,000 that would, many thousands of years later, 294 00:20:38,080 --> 00:20:41,720 manifest spectacularly in the enigmatic machinery 295 00:20:41,800 --> 00:20:43,440 of the Mayan calendar. 296 00:20:44,680 --> 00:20:46,160 But to what end? 297 00:20:46,240 --> 00:20:48,960 I suggest the answer has everything to do 298 00:20:49,040 --> 00:20:52,600 with the Mayan concept of the impermanence of world ages. 299 00:20:54,240 --> 00:20:58,320 I sometimes think of the Mayan calendar as a computer for calculating 300 00:20:58,400 --> 00:21:00,800 not the end of the world, but the end of an age. 301 00:21:02,320 --> 00:21:05,680 The Mayan calendar envisages repeated destructions 302 00:21:05,760 --> 00:21:07,440 and re-makings of the world. 303 00:21:07,520 --> 00:21:10,160 Repeated world ages come and go. 304 00:21:11,680 --> 00:21:14,160 It was never correct that the Maya imagined 305 00:21:14,240 --> 00:21:18,640 the world would end on December 21st, A.D. 2012. 306 00:21:19,600 --> 00:21:24,560 But they do see an episode of great turbulence and change, 307 00:21:24,640 --> 00:21:27,720 uh, taking place at around our time. 308 00:21:29,600 --> 00:21:35,400 Certainly, the end of an age is predicted for roughly the 80-year period 309 00:21:35,480 --> 00:21:38,840 from about 2000 to 2080, somewhere in that period. 310 00:21:40,040 --> 00:21:43,560 And it's curious that actually that is our experience of the world today. 311 00:21:43,640 --> 00:21:47,080 We're living in a time of chaos, of unpredictability, of change. 312 00:21:48,720 --> 00:21:53,200 Could the Mayan calendar's timing for the end of our current age be accurate? 313 00:21:54,880 --> 00:21:57,360 Perhaps we should be gazing up at the heavens, 314 00:21:57,440 --> 00:21:59,760 tracking the stars and planets as they did… 315 00:22:01,560 --> 00:22:04,600 …in case another world-changing apocalypse is imminent. 316 00:22:12,800 --> 00:22:17,480 But there was more to the Maya's interest in the heavens than predicting the future. 317 00:22:20,840 --> 00:22:25,200 There's evidence right here at Palenque that Dr. Barnhart wants to show me. 318 00:22:27,200 --> 00:22:29,880 This view out here, there's a perfect place 319 00:22:29,960 --> 00:22:31,520 where you can see the horizon. 320 00:22:34,840 --> 00:22:39,240 On the southwestern edge of a plaza across from the Temple of the Sun, 321 00:22:39,320 --> 00:22:42,680 Dr. Barnhart is taking me to another powerful edifice 322 00:22:42,760 --> 00:22:44,960 known as the Temple of the Foliated Cross. 323 00:22:47,200 --> 00:22:50,400 It dates from around A.D. 692. 324 00:22:56,440 --> 00:23:01,320 Inside on the back wall, a curious carved mural awaits us. 325 00:23:03,920 --> 00:23:05,720 Scholars now believe it addresses 326 00:23:05,800 --> 00:23:08,960 the great central mystery of Maya religion, 327 00:23:09,560 --> 00:23:12,720 the mystery of what happens to us after death. 328 00:23:14,120 --> 00:23:18,120 We are standing in front of an extraordinary mural, 329 00:23:18,640 --> 00:23:21,480 which is quite difficult for me to interpret. 330 00:23:22,560 --> 00:23:24,960 Tell me what you make of it. What's it all about? 331 00:23:25,680 --> 00:23:28,840 Well, it's obviously so complex. 332 00:23:28,920 --> 00:23:31,680 The iconography is everywhere on this. 333 00:23:31,760 --> 00:23:32,760 Mm-hmm. 334 00:23:32,840 --> 00:23:36,560 There's the foliated cross because of this foliation coming out. 335 00:23:36,640 --> 00:23:37,920 Mm-hmm. 336 00:23:38,000 --> 00:23:40,360 We also have our two figures on either side. 337 00:23:42,400 --> 00:23:45,880 The mural shows the deceased Lord Pakal on the right, 338 00:23:45,960 --> 00:23:48,600 the original founder and ruler of Palenque, 339 00:23:49,840 --> 00:23:52,560 his eyes closed and dressed in burial clothes, 340 00:23:54,160 --> 00:23:58,760 and what's assumed to be his son and successor, Kan Bahlam, on the left. 341 00:24:00,040 --> 00:24:02,000 Here's Kan Bahlam's face. 342 00:24:02,080 --> 00:24:06,080 His portrait is everywhere in the city. We know exactly that is him. 343 00:24:06,160 --> 00:24:08,080 - Yeah. - We recognize him. 344 00:24:08,160 --> 00:24:09,480 But he's big and tall. 345 00:24:09,560 --> 00:24:10,880 - Kan Bahlam. - Yeah. 346 00:24:10,960 --> 00:24:12,800 I always… I think about him. 347 00:24:12,880 --> 00:24:15,440 We have such a wonderful, rich history of his life. 348 00:24:15,520 --> 00:24:16,360 Yeah. 349 00:24:16,440 --> 00:24:21,080 We know that his dad was the most famous king of this city. 350 00:24:21,680 --> 00:24:26,040 And he was named heir-designate at age six. 351 00:24:27,080 --> 00:24:29,160 But his dad didn't die until 80. 352 00:24:30,120 --> 00:24:34,840 So he spent his entire life, until 48, to be the king. 353 00:24:35,360 --> 00:24:38,160 - Right. - And I think he was incredibly trained 354 00:24:38,240 --> 00:24:42,240 in mathematics, architecture, astronomy, 355 00:24:42,320 --> 00:24:45,520 - but also religion, mythology. - Mm-hmm. 356 00:24:45,600 --> 00:24:50,640 This group, the three magnificent temples, is his showcase. 357 00:24:50,720 --> 00:24:54,800 This guy probably planned this for 30 years of his life. 358 00:24:54,880 --> 00:24:57,280 - Mm-hmm. - Finally, he got to build it. 359 00:24:57,360 --> 00:25:01,240 And it's the height of Maya scientific achievement. 360 00:25:01,320 --> 00:25:03,360 - Yeah. - There's numerology. 361 00:25:03,440 --> 00:25:05,200 There's mathematics. There's astronomy. 362 00:25:07,040 --> 00:25:11,680 The message of the mural is that the deeds and rituals performed by the son 363 00:25:12,720 --> 00:25:15,000 are essential if the father is to triumph 364 00:25:15,080 --> 00:25:17,680 in the afterlife journey that now confronts him. 365 00:25:18,440 --> 00:25:22,480 Separating them is an icon of the greatest significance. 366 00:25:23,280 --> 00:25:24,760 Here's our world tree. 367 00:25:24,840 --> 00:25:27,160 That's the sun god's face in the middle of it. 368 00:25:27,680 --> 00:25:32,560 But the tree is also the path between this world and the other world. 369 00:25:33,160 --> 00:25:35,440 In some contexts, it's the Milky Way. 370 00:25:38,240 --> 00:25:42,240 Is the role that the Milky Way plays a… a kind of path of souls? 371 00:25:42,320 --> 00:25:43,960 It's an afterlife journey in some sense? 372 00:25:44,040 --> 00:25:48,120 Yes. The things that these two individuals are interacting with 373 00:25:48,680 --> 00:25:51,000 is the conduit between this world and the other. 374 00:25:51,080 --> 00:25:52,200 Right. 375 00:25:53,120 --> 00:25:56,600 The notion of a leap to the heavens to the Milky Way 376 00:25:56,680 --> 00:25:59,040 and… and a journey that is made after death 377 00:25:59,120 --> 00:26:01,400 is very strong amongst the Maya. 378 00:26:03,800 --> 00:26:07,600 What's remarkable is how widespread this notion is. 379 00:26:09,800 --> 00:26:14,480 This Milky Way symbolism as a… as a path of souls is found 380 00:26:14,560 --> 00:26:16,360 not just amongst the Maya, 381 00:26:16,440 --> 00:26:19,000 but… but amongst many other cultures in North America. 382 00:26:19,080 --> 00:26:23,920 {\an8}Absolutely. It's one of those Pan-American ideas. 383 00:26:24,520 --> 00:26:25,520 {\an8}It really is. 384 00:26:25,600 --> 00:26:28,400 {\an8}From the tip of Chile up to Alaska, 385 00:26:29,360 --> 00:26:34,360 native thought is that the Milky Way is the path of souls 386 00:26:34,440 --> 00:26:36,560 from this world to the other one. 387 00:26:36,640 --> 00:26:40,760 The dead follow it, and the power that shamans have, 388 00:26:40,840 --> 00:26:42,680 - they can walk it. - Right. 389 00:26:43,600 --> 00:26:47,560 But it's… it's fascinating that it's in every single culture 390 00:26:47,640 --> 00:26:50,760 that we can get information about about the Milky Way. 391 00:26:50,840 --> 00:26:52,680 {\an8} 392 00:26:52,760 --> 00:26:58,440 {\an8}It reminds me of how the Apurinã of Brazil view the Amazonian geoglyphs 393 00:26:58,520 --> 00:27:01,480 as if they were sacred portals to the afterlife. 394 00:27:01,560 --> 00:27:04,920 - In the Amazon, it's still very alive. - Yeah. 395 00:27:05,000 --> 00:27:07,400 Here in the Maya world, it's still very much alive. 396 00:27:07,480 --> 00:27:11,640 Yeah. So it's like there's a remote common ancestor to this idea. 397 00:27:12,360 --> 00:27:13,800 I believe so. 398 00:27:15,120 --> 00:27:20,800 I think that these core identity ideas came over with the first people. 399 00:27:20,880 --> 00:27:23,360 And that's why we find them amongst so many cultures, 400 00:27:23,440 --> 00:27:26,320 even though those cultures, for example, in southern Chile 401 00:27:26,400 --> 00:27:29,680 and the far north of North America, are not in contact with one another. 402 00:27:29,760 --> 00:27:33,080 They're still expressing the same ideas because it's the same inheritance. 403 00:27:33,160 --> 00:27:35,760 Absolutely. And I think there's more than just the Milky Way. 404 00:27:35,840 --> 00:27:39,200 There's a couple of different things that are those core principles. 405 00:27:39,280 --> 00:27:42,320 One of them is that the Maya have a great love 406 00:27:42,400 --> 00:27:46,040 of the concepts of shamanism, transformation. 407 00:27:46,120 --> 00:27:46,960 Yeah. 408 00:27:53,680 --> 00:27:57,720 There's no doubt that Mayan culture was a shamanistic culture. 409 00:27:59,120 --> 00:28:03,480 I think that the idea of the journey of the soul after death 410 00:28:04,240 --> 00:28:07,240 results ultimately from shamanistic experiences. 411 00:28:14,640 --> 00:28:17,880 Is it a coincidence that many of the other Indigenous cultures 412 00:28:17,960 --> 00:28:18,960 of the Americas, 413 00:28:19,040 --> 00:28:22,520 and indeed many ancient cultures all around the world, 414 00:28:22,600 --> 00:28:26,840 preserved an almost identical vision of the afterlife journey of the soul? 415 00:28:27,320 --> 00:28:30,880 Or are we confronted here by some underlying connection, 416 00:28:31,520 --> 00:28:34,520 a powerful, all-pervading belief system 417 00:28:34,600 --> 00:28:38,080 that was inherited by many later civilizations 418 00:28:38,160 --> 00:28:41,040 from a lost civilization of prehistory? 419 00:28:51,960 --> 00:28:54,760 The work that you've shared has been very exciting. 420 00:28:54,840 --> 00:28:57,560 And when we see archaeological examples of… 421 00:28:58,160 --> 00:29:01,400 {\an8}of the knowledge of the sky and the stars, 422 00:29:01,480 --> 00:29:05,440 as we look back on it, I feel like it is older than we think. 423 00:29:05,520 --> 00:29:06,640 Yeah. 424 00:29:06,720 --> 00:29:11,160 And you connect this idea to a shamanistic point of view. 425 00:29:11,240 --> 00:29:12,600 Yes, absolutely. 426 00:29:12,680 --> 00:29:15,480 All shamanistic cultures are very interested in the stars. 427 00:29:16,720 --> 00:29:19,880 But at a certain point, that interest in the stars can become a religion. 428 00:29:21,000 --> 00:29:24,360 Can you dig a little bit into that for me? 429 00:29:24,440 --> 00:29:27,400 Shamanism is a system to investigate the mystery of death. 430 00:29:29,320 --> 00:29:31,000 What happens to us when we die? 431 00:29:31,520 --> 00:29:36,200 This notion that the soul leaves the body, leaps up to the heavens. 432 00:29:36,840 --> 00:29:39,720 It was about the journey of the soul after death. 433 00:29:40,440 --> 00:29:44,480 It seems like in our stories and our own journey, 434 00:29:44,560 --> 00:29:47,560 as we grow up, there's this fact of death. 435 00:29:48,800 --> 00:29:49,920 There's the end. 436 00:29:50,880 --> 00:29:52,720 Yeah. It's the essence of everything. 437 00:29:52,800 --> 00:29:55,240 It's a kind of morbid subject to discuss, 438 00:29:55,320 --> 00:29:57,520 but it's fundamental for all human beings. 439 00:29:57,600 --> 00:29:59,320 We're all… we're all facing that moment. 440 00:29:59,920 --> 00:30:04,880 Classically, it's described as a driving force for our actions. 441 00:30:04,960 --> 00:30:06,360 Yeah. Yeah. 442 00:30:06,440 --> 00:30:10,680 I'm going to die, so I will do something. 443 00:30:10,760 --> 00:30:15,600 Yeah. And that's… that's exactly what the shamanistic teachings are saying, 444 00:30:16,120 --> 00:30:20,280 uh, is that we had better use this opportunity of life well. 445 00:30:20,360 --> 00:30:24,480 Yeah. I think that is the challenge that's before us. 446 00:30:25,080 --> 00:30:27,880 Because that idea is found all around the world, 447 00:30:28,400 --> 00:30:31,080 very… very specifically the leap to the Milky Way. 448 00:30:31,160 --> 00:30:33,520 I don't think that could have happened by accident. 449 00:30:33,600 --> 00:30:36,040 I think it's… I think it's something that's been passed on 450 00:30:36,120 --> 00:30:37,720 from an ancestor culture. 451 00:30:37,800 --> 00:30:38,640 Yeah. 452 00:30:42,440 --> 00:30:44,320 But when was it passed on? 453 00:30:45,400 --> 00:30:49,440 Just how far back can we trace this shamanistic tradition 454 00:30:50,480 --> 00:30:53,080 of measuring and tracking objects in the heavens? 455 00:30:53,840 --> 00:30:57,560 The answers just might lie at one of the first places I visited 456 00:30:57,640 --> 00:30:59,400 on my journey through the Americas, 457 00:31:00,240 --> 00:31:05,200 deep in the Amazon rainforest at the ancient site of Serra Do Paituna. 458 00:31:17,360 --> 00:31:21,320 The stone was used as a canvas, uh, for extraordinary art, 459 00:31:21,400 --> 00:31:25,120 and that art itself needs to be deciphered. 460 00:31:25,200 --> 00:31:26,800 It needs to be better understood. 461 00:31:30,520 --> 00:31:32,320 In an attempt to do just that, 462 00:31:32,400 --> 00:31:35,840 {\an8}archaeologist Dr. Christopher Davis became intrigued by 463 00:31:35,920 --> 00:31:38,800 this prominent grid image full of symbols. 464 00:31:42,480 --> 00:31:46,200 Now, talk to me about what we're looking at here 465 00:31:46,280 --> 00:31:49,280 and what you make of it. What's your analysis of this? 466 00:31:49,360 --> 00:31:53,080 It's the largest single painted image at this site. 467 00:31:53,160 --> 00:31:54,960 - There's 49 total boxes. - Yeah. 468 00:31:55,040 --> 00:31:58,000 One of the first difficulties was trying to figure out 469 00:31:58,080 --> 00:31:59,640 should we, you know, look at this 470 00:31:59,720 --> 00:32:01,920 from the left to the right or right to the left. 471 00:32:03,000 --> 00:32:05,640 It seems the ancient painters left a clue. 472 00:32:07,120 --> 00:32:09,480 Here you can see this snake image here. 473 00:32:09,560 --> 00:32:12,560 That's fascinating. So there is an image of a snake there. 474 00:32:12,640 --> 00:32:14,080 Right here in yellow. 475 00:32:14,160 --> 00:32:17,920 Mmm. So almost having the snake there is telling us how to read it. 476 00:32:18,000 --> 00:32:21,160 Exactly. The pattern that pops out to me 477 00:32:21,240 --> 00:32:23,800 is when this grid is read 478 00:32:23,880 --> 00:32:26,600 in a sinusoidal pattern starting at the bottom. 479 00:32:28,840 --> 00:32:30,680 In a sinusoidal pattern, 480 00:32:30,760 --> 00:32:33,760 the boxes read up one column, then down the next, 481 00:32:34,280 --> 00:32:36,560 then up again, like that snake. 482 00:32:37,880 --> 00:32:39,160 But to what end? 483 00:32:40,960 --> 00:32:42,400 When he looked to the west, 484 00:32:42,480 --> 00:32:46,400 Dr. Davis noticed a natural notch in this rocky pillar nearby. 485 00:32:48,160 --> 00:32:51,880 If you're standing right in front, in the background to your right 486 00:32:51,960 --> 00:32:57,160 there's a rock window that the sun, as it passes over here and sets, 487 00:32:57,240 --> 00:32:59,560 eventually it intersects that rock window. 488 00:32:59,640 --> 00:33:03,720 So I believe that they were possibly taking a tally of the sun. 489 00:33:06,000 --> 00:33:10,000 Dr. Davis calls this tally a sunset capture tracker, 490 00:33:10,680 --> 00:33:14,200 an ingenious way to record the sun's movements over time, 491 00:33:15,240 --> 00:33:20,720 one created more than 13,000 years ago during the last Ice Age. 492 00:33:21,880 --> 00:33:23,160 But how does it work? 493 00:33:24,560 --> 00:33:27,400 I see X marks, and I see single lines as well. 494 00:33:28,000 --> 00:33:31,440 - These Xs, these are all together. - Yeah. 495 00:33:31,520 --> 00:33:35,840 And if you read up and down this way, 496 00:33:36,720 --> 00:33:39,280 eventually you get all of these single lines together. 497 00:33:39,360 --> 00:33:43,720 These single vertical lines go together, and then you go back to the Xs. 498 00:33:43,800 --> 00:33:46,960 These single vertical lines are the boxes 499 00:33:47,040 --> 00:33:49,960 that I think coincide with the sun capturing. 500 00:33:50,040 --> 00:33:53,280 And that time is sometime around what would've been the winter solstice. 501 00:33:53,360 --> 00:33:56,200 How clever can you get? That's amazing. 502 00:34:02,640 --> 00:34:04,200 It's not just the grid. 503 00:34:06,280 --> 00:34:10,840 Dr. Davis believes that nearly all of the prehistoric art here tracks the sun. 504 00:34:11,920 --> 00:34:14,560 There's a lot of concentric circles and other images 505 00:34:14,640 --> 00:34:16,840 that appear to be the sun. 506 00:34:16,920 --> 00:34:20,280 And they specifically are pointed to the winter solstice, 507 00:34:20,360 --> 00:34:23,000 and they wrap all the way around to the summer solstice. 508 00:34:24,040 --> 00:34:27,560 More art, facing due west, marks the equinoxes. 509 00:34:28,480 --> 00:34:32,280 So again, it shows this almost obsessive focus 510 00:34:32,360 --> 00:34:34,280 with the key moments of the solar year. 511 00:34:34,360 --> 00:34:35,520 Yes, absolutely. 512 00:34:37,480 --> 00:34:41,720 What we have here may well be the earliest evidence yet found 513 00:34:41,800 --> 00:34:43,480 anywhere in the Americas 514 00:34:43,560 --> 00:34:46,240 of humans keeping tallies of celestial events. 515 00:34:48,720 --> 00:34:52,080 So in a way, this whole thing is kind of a huge machine 516 00:34:52,160 --> 00:34:54,480 for tracking the passage of time? 517 00:34:55,000 --> 00:34:57,160 I believe so. I believe it's like an almanac 518 00:34:57,240 --> 00:34:58,760 that's written in pictures. 519 00:35:01,120 --> 00:35:07,480 This speaks to a scientific mindset amongst the artists themselves, 520 00:35:07,560 --> 00:35:10,000 as though they're observing particular incidents 521 00:35:10,080 --> 00:35:11,320 and moments in the sky… 522 00:35:13,800 --> 00:35:16,920 and getting to grips with the science of time 523 00:35:17,960 --> 00:35:20,960 and thus the ability to predict what would happen 524 00:35:21,040 --> 00:35:22,960 at particular dates in the future. 525 00:35:25,120 --> 00:35:27,440 So it was a kind of scientific project for them? 526 00:35:27,520 --> 00:35:28,840 Absolutely, yeah. 527 00:35:28,920 --> 00:35:32,080 The art itself looks very shamanistic to me. 528 00:35:32,160 --> 00:35:33,920 That's just my personal impression. 529 00:35:34,000 --> 00:35:35,880 Do you think shamans were at work here? 530 00:35:35,960 --> 00:35:37,240 It's possible. 531 00:35:37,320 --> 00:35:41,480 They carried several occupations, scientists, doctors, all sorts of things. 532 00:35:41,560 --> 00:35:42,400 Yeah. 533 00:35:42,480 --> 00:35:44,800 They usually do carry sacred knowledge, 534 00:35:44,880 --> 00:35:47,040 things like the movement of the stars. 535 00:35:48,080 --> 00:35:51,440 Do you see that spread widely across the Americas? 536 00:35:51,520 --> 00:35:52,400 Yeah. 537 00:35:52,480 --> 00:35:56,160 The knowledge of using astronomy in this way is found throughout here. 538 00:35:56,240 --> 00:35:57,520 So the Maya… 539 00:35:59,400 --> 00:36:02,240 and other cultures seem to be using this. 540 00:36:04,000 --> 00:36:07,120 In the American Southwest, we had chiefs who were sun watchers. 541 00:36:08,080 --> 00:36:11,800 So all of this lore does seem to go back far in time… 542 00:36:11,880 --> 00:36:14,640 - Yeah. - …uh, to some deep understanding 543 00:36:15,240 --> 00:36:17,440 that had spread throughout much of the Americas. 544 00:36:20,040 --> 00:36:25,000 This obsession with the heavens is just one of many recurring themes 545 00:36:25,600 --> 00:36:30,040 I've encountered again and again all across the Americas… 546 00:36:33,800 --> 00:36:37,400 …ideas that play a central role in my 30-year quest 547 00:36:37,480 --> 00:36:39,760 for a forgotten episode in human history. 548 00:36:45,720 --> 00:36:48,240 The question is, where did these ideas come from? 549 00:36:48,320 --> 00:36:53,640 For me, these are indications of a remote common source, 550 00:36:53,720 --> 00:36:57,880 that these ideas have filtered down through many different human cultures, 551 00:36:57,960 --> 00:37:00,640 but the ideas themselves have remained relatively intact. 552 00:37:02,360 --> 00:37:06,160 Unless it's some just extraordinary, unbelievable coincidence, 553 00:37:06,680 --> 00:37:09,160 we are looking at a legacy which has been handed down 554 00:37:09,240 --> 00:37:12,080 from the remotest antiquity and has been preserved 555 00:37:12,160 --> 00:37:13,480 and passed on and developed 556 00:37:13,560 --> 00:37:16,560 by multiple different cultures all around the Americas. 557 00:37:20,120 --> 00:37:23,400 A legacy perhaps left by a seafaring people 558 00:37:23,480 --> 00:37:26,480 capable of crossing oceans as wide as the Pacific 559 00:37:27,440 --> 00:37:31,040 thousands of years before scholars accept such voyages were possible. 560 00:37:32,360 --> 00:37:35,520 A culture that understood how to harness the power of plants 561 00:37:36,040 --> 00:37:38,040 to create mind-enhancing visions 562 00:37:39,760 --> 00:37:43,560 of geometric patterns and encounters with fantastical beings, 563 00:37:44,280 --> 00:37:48,760 visions of such great importance they would become the basis of their art. 564 00:37:50,320 --> 00:37:52,400 And a culture that shared its knowledge 565 00:37:52,480 --> 00:37:56,160 of how to create technologically-advanced structures, 566 00:37:56,240 --> 00:37:58,120 whether built in stone 567 00:37:58,200 --> 00:38:00,200 or made from the body of the earth herself, 568 00:38:01,360 --> 00:38:03,480 structures with great spiritual meaning, 569 00:38:03,560 --> 00:38:05,960 designed to bind ground to sky, 570 00:38:06,640 --> 00:38:09,240 celebrating the soul's journey into the afterlife. 571 00:38:10,440 --> 00:38:13,440 In fact, I would suggest these common religious 572 00:38:13,520 --> 00:38:16,800 and spiritual motifs that are found all around the world 573 00:38:16,880 --> 00:38:21,200 are amongst the best evidence for a lost civilization of prehistory… 574 00:38:23,840 --> 00:38:25,640 …that we're ever going to find. 575 00:38:26,200 --> 00:38:30,200 Oh my God. We're taking on every childhood misconception 576 00:38:30,280 --> 00:38:33,800 of the story of… of the world. 577 00:38:33,880 --> 00:38:36,760 The story of the peopling of the Americas is changing, 578 00:38:36,840 --> 00:38:38,680 and I'll give credit to science for that. 579 00:38:38,760 --> 00:38:43,000 It's scientific archaeology that is… that is unveiling this new information. 580 00:38:45,000 --> 00:38:48,560 What I'm saying is that old ideas are being pushed aside. 581 00:38:49,280 --> 00:38:52,240 It's very clear that stuff just keeps on getting older. 582 00:38:53,600 --> 00:38:56,520 What new evidence will come to light next?
