1 00:00:11,800 --> 00:00:15,000 We need to re-examine the pre-history of Easter Island. 2 00:00:18,200 --> 00:00:20,760 We shouldn't just accept what we're told. 3 00:00:24,480 --> 00:00:28,800 {\an8}Rapa Nui resident and archaeologist Dr. Sonia Haoa Cardinali 4 00:00:28,880 --> 00:00:32,960 {\an8}has spent nearly five decades recovering the island's lost history, 5 00:00:35,080 --> 00:00:38,880 not by studying the Moai or ancient settlements, 6 00:00:38,960 --> 00:00:42,040 but through a close investigation of its plants. 7 00:00:42,960 --> 00:00:47,320 So, Sonia, I understand that you have a special interest in botany, 8 00:00:47,400 --> 00:00:48,920 but you're also an archaeologist. 9 00:00:49,000 --> 00:00:52,120 Yes. The most important for me 10 00:00:52,200 --> 00:00:55,560 is to understand the people. 11 00:00:55,640 --> 00:00:58,840 - Yeah. - Is to understand how people arrive, 12 00:00:58,920 --> 00:01:02,800 is to understand how people adapted to this island 13 00:01:03,400 --> 00:01:08,680 because as a human, we cannot do anything without plants. 14 00:01:12,040 --> 00:01:15,440 In the bowl of one of Rapa Nui's extinct volcanoes, 15 00:01:15,520 --> 00:01:18,040 Dr. Cardinali and her colleagues have been searching for 16 00:01:18,120 --> 00:01:21,800 the earliest evidence of non-indigenous plants or crops 17 00:01:21,880 --> 00:01:24,200 that must have been brought here by humans. 18 00:01:25,960 --> 00:01:29,040 What do plants say about when people lived on this island? 19 00:01:29,120 --> 00:01:34,400 In the study of the different food we have, the result came… 20 00:01:34,480 --> 00:01:35,720 Yes. 21 00:01:36,360 --> 00:01:37,200 …with the banana. 22 00:01:39,360 --> 00:01:43,760 They found the banana on the island 3,000 years ago. 23 00:01:43,840 --> 00:01:48,520 So bananas have been on Rapa Nui for at least 3,000 years? 24 00:01:48,600 --> 00:01:49,600 Yes. Yes. 25 00:01:52,640 --> 00:01:54,960 And they didn't get here by themselves. 26 00:01:56,440 --> 00:01:59,120 It's not coming by the birds. 27 00:01:59,200 --> 00:02:01,320 It's not by the sea. 28 00:02:01,400 --> 00:02:05,920 The banana had to be planted by another human being. 29 00:02:07,440 --> 00:02:10,400 So that's the reason it's telling you 30 00:02:10,480 --> 00:02:16,240 that in Rapa Nui, there is a different period of people arrived. 31 00:02:16,320 --> 00:02:17,160 Yeah. 32 00:02:17,240 --> 00:02:19,400 And it's a huge surprise for everybody. 33 00:02:19,480 --> 00:02:21,600 It's changed, a little bit, the history. 34 00:02:21,680 --> 00:02:23,880 Well, it changes a lot the history. 35 00:02:23,960 --> 00:02:25,720 The soil is not lying. 36 00:02:26,320 --> 00:02:27,800 No, the soil tells the truth. 37 00:02:27,880 --> 00:02:33,240 We didn't think that the banana was so important. 38 00:02:36,840 --> 00:02:39,240 Dr. Cardinali's dates were derived 39 00:02:39,320 --> 00:02:41,840 from microscopic remnants of banana plants 40 00:02:42,600 --> 00:02:48,640 and pushed the arrival of people on Rapa Nui back by around 2,000 years. 41 00:02:52,720 --> 00:02:55,720 So the plants are helping us to push the timeline back. 42 00:02:55,800 --> 00:02:56,640 Yes. 43 00:02:56,720 --> 00:02:59,400 And it's possible it may be older than 3,000 years. 44 00:02:59,480 --> 00:03:04,760 We don't know. But that's the reason we should continue to study. 45 00:03:04,840 --> 00:03:05,800 Absolutely. 46 00:03:08,200 --> 00:03:10,160 In light of this new evidence, 47 00:03:10,240 --> 00:03:13,320 Rapa Nui's prehistory has to be reconsidered. 48 00:03:14,560 --> 00:03:19,360 Dr. Cardinali's findings suggest that Polynesian settlers reached this island 49 00:03:19,440 --> 00:03:21,560 long before the accepted timeline. 50 00:03:22,440 --> 00:03:26,720 But based on Rapa Nui's oral traditions, there is another possibility. 51 00:03:28,440 --> 00:03:32,600 Perhaps Hotu Matu'a and his seven scouts arrived here 52 00:03:32,680 --> 00:03:36,520 many thousands of years earlier than anyone ever dreamed possible. 53 00:03:39,960 --> 00:03:43,760 Might there not be a forgotten episode in the story of this island? 54 00:03:44,240 --> 00:03:48,560 An earlier chapter written by survivors of the global cataclysm 55 00:03:48,640 --> 00:03:51,160 that occurred around 12,000 years ago? 56 00:04:07,760 --> 00:04:10,360 {\an8}- 57 00:04:14,760 --> 00:04:18,480 If humans arrived on Rapa Nui many thousands of years ago, 58 00:04:19,080 --> 00:04:20,320 where did they live? 59 00:04:21,720 --> 00:04:25,240 Where are the archaeological traces we'd expect to find? 60 00:04:27,400 --> 00:04:29,960 Remember that at the peak of the last Ice Age, 61 00:04:30,040 --> 00:04:33,600 sea levels were more than 400 feet lower than they are today. 62 00:04:34,200 --> 00:04:36,640 Rapa Nui would have been a much larger island. 63 00:04:38,800 --> 00:04:42,480 All that land could have supported a much larger population… 64 00:04:45,040 --> 00:04:48,800 …which could help explain how the huge Moai carving project 65 00:04:48,880 --> 00:04:49,760 was pulled off. 66 00:04:52,560 --> 00:04:56,280 Might their builders have chosen to live near the ancient coastline, 67 00:04:56,360 --> 00:04:57,800 now lost underwater 68 00:05:00,400 --> 00:05:02,640 and only used the higher ground we see today 69 00:05:02,720 --> 00:05:05,080 for their great statue-building project? 70 00:05:06,800 --> 00:05:11,840 It's not often realized how much land was lost to sea level rise 71 00:05:11,920 --> 00:05:13,120 at the end of the Ice Age, 72 00:05:13,200 --> 00:05:16,880 and the figure is roughly 10 million square miles, 73 00:05:17,600 --> 00:05:19,640 the best land in the world at that time. 74 00:05:20,680 --> 00:05:22,640 And when the sea levels suddenly rise, 75 00:05:22,720 --> 00:05:26,160 and those coastlines get submerged beneath the sea, 76 00:05:27,360 --> 00:05:31,840 anything built on those submerged areas gets smashed to pieces and destroyed. 77 00:05:33,160 --> 00:05:36,480 And goodness knows what was lost to the rising sea levels. 78 00:05:45,800 --> 00:05:49,840 What we do know is that the earliest people living here 79 00:05:49,920 --> 00:05:53,400 developed more than just extraordinary stone-carving skills. 80 00:05:58,000 --> 00:06:02,320 Rapa Nui lore holds that their great founder, King Hotu Matu'a, 81 00:06:02,920 --> 00:06:05,960 brought something special with him from that far-off land of Hiva, 82 00:06:07,120 --> 00:06:08,280 a written language. 83 00:06:11,520 --> 00:06:16,000 Its remnants were preserved on wooden tablets known as rongorongo, 84 00:06:17,000 --> 00:06:20,320 most likely copies of copies created down the ages, 85 00:06:20,400 --> 00:06:22,880 as the originals were lost to history. 86 00:06:23,840 --> 00:06:26,280 Fewer than 30 rongorongo survive, 87 00:06:27,000 --> 00:06:29,800 now preserved in museums around the world. 88 00:06:31,280 --> 00:06:32,680 For Rapa Nui residents 89 00:06:32,760 --> 00:06:35,720 like Indigenous documentarian Leo Pakarati, 90 00:06:36,240 --> 00:06:39,120 these tablets hold a special place in history. 91 00:06:40,080 --> 00:06:42,840 It's an incredible achievement because normally a written script 92 00:06:42,920 --> 00:06:46,600 is associated with a big, highly-organized culture. 93 00:06:46,680 --> 00:06:49,480 {\an8}- Here we're finding it on a small island. Mm-hmm. 94 00:06:49,560 --> 00:06:53,320 The rongorongo are very interesting and very important in our culture. 95 00:06:53,400 --> 00:06:55,640 - And I think it's unique in Polynesia. - Yeah. 96 00:06:55,720 --> 00:06:58,640 Yeah, it's unique. There's no rongorongo on other islands. 97 00:07:00,320 --> 00:07:03,400 With the slave raids in the 19th century 98 00:07:03,480 --> 00:07:07,280 and the complete destruction of the wisdom tradition of Easter Island, 99 00:07:07,360 --> 00:07:10,640 the ability to read the rongorongo tablets was lost, 100 00:07:10,720 --> 00:07:15,200 and they remain one of the great mysteries of the ancient world. 101 00:07:16,160 --> 00:07:19,560 Linguists have determined that there are too many different symbols 102 00:07:19,640 --> 00:07:22,160 for the rongorongo script to be an alphabet. 103 00:07:24,040 --> 00:07:27,360 It's likely a hieroglyphic or a pictographic script, 104 00:07:27,440 --> 00:07:30,520 similar to those developed by the ancient Egyptians 105 00:07:30,600 --> 00:07:32,680 and the Indus Valley civilization, 106 00:07:34,000 --> 00:07:38,200 one that must have taken hundreds if not thousands of years to mature. 107 00:07:40,000 --> 00:07:42,760 The rongorongo system is very complex. 108 00:07:42,840 --> 00:07:47,720 You need many elements, you know, peace, water, food, society, you know. 109 00:07:48,560 --> 00:07:51,840 This is a very intellectual, complex process. 110 00:07:52,520 --> 00:07:55,400 For centuries, up until the Europeans arrived, 111 00:07:56,000 --> 00:07:58,640 the written language was celebrated through song. 112 00:07:59,240 --> 00:08:03,720 But the connection between sounds and symbols has long been forgotten. 113 00:08:04,240 --> 00:08:06,760 The people don't learn to read. 114 00:08:06,840 --> 00:08:08,920 - They learn only the song. - Mm-hmm. 115 00:08:09,000 --> 00:08:11,160 And for a long time, the song continued. 116 00:08:11,240 --> 00:08:13,800 What sort of things do these songs speak of? 117 00:08:14,280 --> 00:08:15,720 Agricultural system. 118 00:08:15,800 --> 00:08:18,520 - Yeah. - And the rules for navigation. 119 00:08:18,600 --> 00:08:19,480 Mm-hmm. 120 00:08:19,560 --> 00:08:22,400 The inventory to the different genealogical lines. 121 00:08:22,480 --> 00:08:23,440 Mm-hmm. 122 00:08:23,520 --> 00:08:25,680 The territory owners, things like this. 123 00:08:25,760 --> 00:08:26,600 Yeah. 124 00:08:26,680 --> 00:08:28,600 For me, the rongorongo, 125 00:08:28,680 --> 00:08:34,960 maybe it's the most important thing made by our Tupuna, our ancestors. 126 00:08:37,080 --> 00:08:40,960 The presence of a fully evolved, complex script on Easter Island 127 00:08:41,040 --> 00:08:44,920 is a paradox and a mystery, which has not yet been explained. 128 00:08:48,400 --> 00:08:50,760 I think the possibility has to be considered 129 00:08:50,840 --> 00:08:57,080 that that script was first brought to Easter Island in remote prehistory 130 00:08:57,160 --> 00:09:01,000 by those first settlers who are remembered in oral tradition 131 00:09:01,080 --> 00:09:04,880 as having come from a much larger land of the Pacific called Hiva 132 00:09:04,960 --> 00:09:09,880 that was inundated in an enormous flood and submerged beneath the waves. 133 00:09:11,120 --> 00:09:14,080 I realize this is speculation on my part, 134 00:09:14,600 --> 00:09:18,200 but could we be looking at the actual language 135 00:09:18,280 --> 00:09:21,640 used by the lost civilization I've been searching for?

326 00:24:02,120 --> 00:24:06,360 The heaviest here weighed more than 100 tons. 327 00:24:06,440 --> 00:24:07,360 Good Lord. 328 00:24:12,680 --> 00:24:16,840 What puzzles me is the movement of those huge blocks. 329 00:24:16,920 --> 00:24:19,320 I just can't understand how it was done. 330 00:24:19,400 --> 00:24:23,040 In my opinion, the secret was in the quantity. 331 00:24:23,120 --> 00:24:27,640 Pedro Cieza de León was a Spanish soldier and chronicler, 332 00:24:27,720 --> 00:24:29,680 and according to him, 333 00:24:29,760 --> 00:24:34,040 every day more than 20,000 people were working here. 334 00:24:34,120 --> 00:24:36,520 That's a huge organizational challenge. 335 00:24:37,040 --> 00:24:40,520 To organize 20,000 people as a workforce 336 00:24:40,600 --> 00:24:42,360 is a highly sophisticated task. 337 00:24:46,800 --> 00:24:50,000 The construction of New York City's Empire State Building 338 00:24:50,080 --> 00:24:54,360 took around 3,400 people in the 20th century. 339 00:24:55,640 --> 00:24:58,120 Even with six times as many workers, 340 00:24:58,200 --> 00:25:02,120 shifting these stones with far less advanced technology 341 00:25:02,200 --> 00:25:06,880 would have been a gargantuan challenge, which could swiftly go wrong. 342 00:25:08,680 --> 00:25:12,520 The only record we have of the Incas attempting to move a huge megalith 343 00:25:13,120 --> 00:25:17,000 was preserved by a Spanish chronicler a few decades after the conquest. 344 00:25:17,080 --> 00:25:20,720 According to the account he was given by local informants, 345 00:25:20,800 --> 00:25:23,240 the attempt ended in disaster. 346 00:25:26,440 --> 00:25:30,160 He tells us of a great boulder that was hauled across the mountain 347 00:25:30,240 --> 00:25:32,240 by more than 20,000 people, 348 00:25:33,880 --> 00:25:38,000 until, at a certain point, it fell from their hands over a precipice… 349 00:25:40,080 --> 00:25:42,080 …crushing more than 3,000 men. 350 00:25:44,800 --> 00:25:48,520 If the Incas had that much trouble transporting one megalith, 351 00:25:48,600 --> 00:25:51,120 how could they have brought thousands of them here? 352 00:25:59,000 --> 00:26:02,280 According to Spanish accounts, the Inca used a combination 353 00:26:02,360 --> 00:26:05,600 of ropes, log rollers, and levers. 354 00:26:08,600 --> 00:26:11,960 You could, with great effort and great care, 355 00:26:12,040 --> 00:26:14,000 put two or three such blocks together, 356 00:26:14,080 --> 00:26:18,760 but to put hundreds of them together, all of them precisely fitted, 357 00:26:18,840 --> 00:26:20,680 it defies logic. 358 00:26:22,680 --> 00:26:26,520 What if that Incan emperor was actually just supervising the building 359 00:26:26,600 --> 00:26:31,920 of a fortress atop megalithic walls that were already there? 360 00:26:34,080 --> 00:26:38,120 It's hard to imagine the spectacle that must have greeted the eye here 361 00:26:38,200 --> 00:26:40,160 before the Spanish conquest. 362 00:26:40,240 --> 00:26:42,520 But combining the latest scientific data 363 00:26:42,600 --> 00:26:45,440 with eyewitness accounts left by the first conquistadors, 364 00:26:45,520 --> 00:26:49,360 we can get a fairly good idea how Sacsayhuaman must have looked 365 00:26:49,440 --> 00:26:51,280 at the height of the Inca Empire. 366 00:26:56,920 --> 00:26:59,320 The Spanish tell us that the main complex 367 00:26:59,400 --> 00:27:03,960 was being used as a military barracks, capable of holding thousands. 368 00:27:09,120 --> 00:27:11,960 They describe a three-layered circular tower 369 00:27:12,040 --> 00:27:14,040 soaring 50 feet above the site, 370 00:27:15,200 --> 00:27:18,200 surrounded by rectangular buildings and courtyards, 371 00:27:19,560 --> 00:27:23,040 with their own freshwater system and storerooms for grain. 372 00:27:26,200 --> 00:27:30,160 The invaders believed Sacsayhuaman was first built as a fortress 373 00:27:31,680 --> 00:27:34,560 because, after the fall of Cusco, 374 00:27:34,640 --> 00:27:38,520 the Inca warriors made their last redoubt from behind these walls… 375 00:27:42,280 --> 00:27:44,200 …which are all that remain today. 376 00:27:46,600 --> 00:27:48,600 But is that why they were built? 377 00:27:50,920 --> 00:27:56,120 What is the archaeological view of the origins of Sacsayhuaman, 378 00:27:56,200 --> 00:27:57,600 and what was it for? 379 00:27:58,200 --> 00:28:01,680 Many people think that it was military construction. 380 00:28:02,280 --> 00:28:07,920 Only Spaniards or conquistadors told them it was a military fortress, but it wasn't. 381 00:28:08,000 --> 00:28:13,360 It was a holy place, a temple, to celebrate the rituals and ceremonies. 382 00:28:15,800 --> 00:28:18,440 So the idea, which we often read in the history books, 383 00:28:18,520 --> 00:28:23,000 that… that Sacsayhuaman was built as a military fortress, is a mistake? 384 00:28:23,080 --> 00:28:24,400 It's a huge mistake. 385 00:28:27,000 --> 00:28:29,440 What's left of the structures atop the hill, 386 00:28:29,920 --> 00:28:32,720 which were made from uniform rectangular blocks, 387 00:28:33,240 --> 00:28:37,480 suggests they weren't built at the same time as the megalithic walls. 388 00:28:39,440 --> 00:28:45,800 It would be fair to say that the Incas inherited some earlier works, 389 00:28:45,880 --> 00:28:48,400 but those earlier works are quite hard to explain. 390 00:28:48,480 --> 00:28:49,360 Yes. 391 00:28:50,080 --> 00:28:53,240 It also suggests they were constructed with a different, 392 00:28:53,320 --> 00:28:56,040 as yet unknown, stone-working technique. 393 00:28:59,720 --> 00:29:03,920 This could be considered, um, lost technology. 394 00:29:06,040 --> 00:29:11,440 We are confronted by mystery, by an enigma that we cannot explain. 395 00:29:12,920 --> 00:29:17,960 Could the smooth, massive, zigzag walls of Sacsayhuaman have been carved 396 00:29:18,040 --> 00:29:21,600 not by the Inca, but by someone else? 397 00:29:27,920 --> 00:29:31,520 What if much of the construction we see here that's attributed to the Incas 398 00:29:32,120 --> 00:29:35,080 actually incorporates a legacy of far more ancient knowledge? 399 00:29:38,360 --> 00:29:40,160 Could there be a legacy in stone, 400 00:29:40,640 --> 00:29:45,320 a legacy from an older civilization, as yet unidentified by archaeology? 401 00:29:48,320 --> 00:29:53,200 After all, no simpler versions of these smoothly fitted megalithic walls 402 00:29:53,800 --> 00:29:55,800 have been found anywhere in Peru. 403 00:29:57,040 --> 00:30:00,600 But we did see something like this back on Rapa Nui… 404 00:30:03,960 --> 00:30:06,120 {\an8}in the walls of Ahu Vinapu, 405 00:30:06,200 --> 00:30:11,880 {\an8}supposedly built long before Sacsayhuaman, more than 2,000 miles away. 406 00:30:14,960 --> 00:30:17,400 The individual blocks are made of solid basalt. 407 00:30:17,480 --> 00:30:19,280 They are beautifully fitted together, 408 00:30:19,360 --> 00:30:23,840 and they include polygonal elements, just like the walls of Sacsayhuaman. 409 00:30:25,200 --> 00:30:30,040 {\an8}Similar construction can be seen in ancient walls in Turkey and in Egypt. 410 00:30:32,120 --> 00:30:34,520 {\an8}There's a particular, a single small block 411 00:30:34,600 --> 00:30:38,320 {\an8}that is fitted in between larger blocks, which is identical. 412 00:30:38,400 --> 00:30:41,280 {\an8}You can find the identical image in Cusco. 413 00:30:43,080 --> 00:30:46,200 {\an8}Some suggest the builders were simply being efficient 414 00:30:46,280 --> 00:30:47,800 {\an8}with leftover waste material. 415 00:30:48,560 --> 00:30:50,560 But just look at the precision. 416 00:30:51,600 --> 00:30:55,120 So the feeling is that this is a technology from the past 417 00:30:55,200 --> 00:30:58,040 that wasn't confined to or limited to Peru. 418 00:31:01,080 --> 00:31:04,280 What if the Incas built some of the structures we see here 419 00:31:04,360 --> 00:31:06,760 on top of far more ancient foundations? 420 00:31:08,280 --> 00:31:10,280 Foundations that may go back 421 00:31:10,360 --> 00:31:13,520 to the very roots of civilization in the Americas. 422 00:31:17,200 --> 00:31:19,280 This possibility is leading me down 423 00:31:19,360 --> 00:31:21,960 to the city over which Sacsayhuaman towers, 424 00:31:22,640 --> 00:31:25,640 a place whose very name might hold a vital clue. 425 00:31:27,360 --> 00:31:29,920 In the original Quechua language of the Inca, 426 00:31:30,000 --> 00:31:32,560 Cusco means "navel of the Earth," 427 00:31:34,200 --> 00:31:37,440 {\an8}just like all those other sacred ancient navels, 428 00:31:37,520 --> 00:31:38,720 {\an8}including Rapa Nui. 429 00:31:41,360 --> 00:31:45,680 This notion of navels being found all around the world 430 00:31:45,760 --> 00:31:48,520 should not be dismissed, in my view, as coincidence. 431 00:31:51,120 --> 00:31:55,520 Could the remarkably shaped stonework we see throughout this navel of the Earth 432 00:31:55,600 --> 00:32:00,440 be another surviving remnant of that far older, advanced civilization 433 00:32:00,520 --> 00:32:01,920 I've been looking for? 434 00:32:06,280 --> 00:32:07,800 Everywhere you look in this city, 435 00:32:07,880 --> 00:32:12,920 there are layers upon layers of beautiful and intricately-shaped stone walls, 436 00:32:13,480 --> 00:32:15,560 some incorporating giant megaliths. 437 00:32:16,480 --> 00:32:18,400 The mystery is that in any wall, 438 00:32:18,480 --> 00:32:21,480 you can often see several different styles of architecture. 439 00:32:21,560 --> 00:32:24,840 Some extremely fine, some comparatively crude. 440 00:32:28,760 --> 00:32:31,840 That mystery has led me to Cusco's Calle Loreto 441 00:32:32,640 --> 00:32:38,040 and archaeological researcher Jesus Gamarra, a descendant of the Inca, 442 00:32:38,120 --> 00:32:42,200 {\an8}who's spent decades studying the unique stonework of ancient Peru. 443 00:32:43,560 --> 00:32:48,520 Tell me about your work in the area of Cusco and the Sacred Valley. 444 00:32:49,120 --> 00:32:54,920 My passion lies in antiquities of human origin. 445 00:32:55,800 --> 00:33:00,040 And this is reflected in the stone 446 00:33:00,120 --> 00:33:04,720 which is the oldest witness that exists in history. 447 00:33:06,840 --> 00:33:09,120 Just as we saw at Sacsayhuaman, 448 00:33:09,200 --> 00:33:12,480 the street's megalithic walls fit seamlessly together, 449 00:33:13,440 --> 00:33:16,880 the stones' curved edges flowing one into the other. 450 00:33:18,400 --> 00:33:20,080 I mean, it boggles the mind. 451 00:33:20,160 --> 00:33:24,520 I'm just stunned looking at this, and I can't figure out 452 00:33:24,600 --> 00:33:28,280 how anybody could have made walls 453 00:33:28,360 --> 00:33:31,560 with these enormous stones so perfectly fitted together. 454 00:33:33,120 --> 00:33:36,200 What the archaeologists teach us is that this was done by the Incas 455 00:33:36,800 --> 00:33:41,680 and that they used simple pounding stones to make all of this incredible work. 456 00:33:42,280 --> 00:33:46,840 It is not possible to make this marvel with chisel technology 457 00:33:46,920 --> 00:33:48,640 and a builder's kit 458 00:33:48,720 --> 00:33:52,120 or to calculate the perfect precision 459 00:33:52,200 --> 00:33:56,360 that exists in this type of expression. 460 00:33:58,360 --> 00:34:01,520 Nowhere is this precision more clear than here 461 00:34:02,280 --> 00:34:06,400 with the geometric feat known as the 12-angled stone… 462 00:34:08,400 --> 00:34:10,960 with its multiple faces fitting seamlessly 463 00:34:11,040 --> 00:34:13,240 with 11 other unique blocks. 464 00:34:16,160 --> 00:34:20,720 And yet something else is jarring about these so-called Incan walls. 465 00:34:23,320 --> 00:34:26,400 I see many different styles of architecture here. 466 00:34:26,480 --> 00:34:28,720 Some amazing stonework like this 467 00:34:28,800 --> 00:34:32,640 and then some much poorer quality stonework side by side. 468 00:34:32,720 --> 00:34:34,280 Help me to understand that mystery. 469 00:34:34,880 --> 00:34:38,680 This architecture does not correspond to the Incas. 470 00:34:40,280 --> 00:34:47,240 The Incas did not use this polygonal, cushioned architecture. 471 00:34:47,760 --> 00:34:51,280 The Incas have another type of architecture, 472 00:34:51,360 --> 00:34:55,040 which is characterized by right angles. 473 00:34:58,360 --> 00:35:01,200 The upper sections feature blocks that clearly show 474 00:35:01,280 --> 00:35:04,760 marks consistent with the basic tools the Inca used. 475 00:35:06,040 --> 00:35:10,720 Their construction poses no mystery, unlike the lower tiers. 476 00:35:12,840 --> 00:35:15,840 So in your view, the Incas did not make this? 477 00:35:15,920 --> 00:35:18,120 No. No, no, no. No. 478 00:35:19,080 --> 00:35:21,400 Jesus believes the Incas built above 479 00:35:21,480 --> 00:35:26,200 and around more ancient walls that were already here when they arrived. 480 00:35:29,480 --> 00:35:34,440 The history of Cusco does not only go back to the Incas, 481 00:35:34,520 --> 00:35:37,680 but much further back. 482 00:35:39,360 --> 00:35:42,600 Jesus Gamarra, he's convinced that we're looking not at one, 483 00:35:42,680 --> 00:35:45,440 but at least at three different styles of architecture, 484 00:35:45,520 --> 00:35:47,080 the work of at least three cultures. 485 00:35:49,280 --> 00:35:53,520 The most recent rough block work, Jesus attributes to the Inca. 486 00:35:54,520 --> 00:35:57,600 But he believes the pre-Inca smoothly-shaped stones 487 00:35:57,680 --> 00:35:59,920 both here and at Sacsayhuaman 488 00:36:00,000 --> 00:36:02,840 have their roots in a far more ancient technique, 489 00:36:03,440 --> 00:36:06,720 one the Incas revered but could not emulate. 490 00:36:10,040 --> 00:36:12,000 There are things that are impossible 491 00:36:12,520 --> 00:36:15,520 for more modern civilizations. 492 00:36:15,600 --> 00:36:18,520 These are more ancient 493 00:36:18,600 --> 00:36:25,200 and prove that moldable stone was used. 494 00:36:26,520 --> 00:36:30,160 Jesus Gamarra calls this style Hanan Pacha. 495 00:36:30,640 --> 00:36:33,000 And to get a first-hand glimpse of it, 496 00:36:33,080 --> 00:36:36,080 he suggests I visit an intriguing site 497 00:36:36,840 --> 00:36:39,760 on the side of the hill topped by Sacsayhuaman. 498 00:36:45,200 --> 00:36:47,360 A truly mystical location 499 00:36:49,640 --> 00:36:53,080 with a secretive entrance all but hidden from view. 500 00:36:56,080 --> 00:36:59,400 One that again shows a curious mix of building styles. 501 00:37:01,880 --> 00:37:04,200 It's known as the Temple of the Moon. 502 00:37:15,280 --> 00:37:19,640 This is a strange, complicated place with an air of mystery about it. 503 00:37:20,560 --> 00:37:23,480 The low stone walls here are typical Inca masonry. 504 00:37:25,240 --> 00:37:28,120 But hidden inside this shaped rocky outcrop 505 00:37:28,200 --> 00:37:30,120 is something altogether different. 506 00:37:34,000 --> 00:37:38,520 You're drawn in through a narrow passageway, 507 00:37:38,600 --> 00:37:40,160 surrounded by silence. 508 00:37:42,360 --> 00:37:45,240 It's almost like entering into a labyrinth. 509 00:37:47,040 --> 00:37:50,560 It looks like some unknown technology that we don't fully understand, 510 00:37:51,200 --> 00:37:55,080 created for reasons that don't make sense to us.
