1
00:00:15,200 --> 00:00:18,440
Ayahuasca is one of
the scientific inventions of the Amazon.
2
00:00:20,040 --> 00:00:21,960
It's a powerful visionary brew,
3
00:00:23,440 --> 00:00:27,760
one that's central to Indigenous
spirituality and legal here in Peru.
4
00:00:29,160 --> 00:00:34,040
I myself have had many experiences
with ayahuasca guided by a shaman.
5
00:00:35,880 --> 00:00:39,400
And I believe its use dates back
further than anyone thinks,
6
00:00:40,040 --> 00:00:42,720
especially in the light
of the artwork it inspires.
7
00:00:45,720 --> 00:00:47,640
There are incredible visions.
8
00:00:47,640 --> 00:00:49,280
Nine times out of ten,
9
00:00:49,280 --> 00:00:51,880
those are introduced
with geometric patterns.
10
00:00:53,360 --> 00:00:55,400
And after these first visions,
11
00:00:55,400 --> 00:00:58,680
many people report encounters
with fantastical beings.
12
00:01:00,360 --> 00:01:05,680
Sometimes those entities may be a mixture
of an animal and a human being,
13
00:01:05,680 --> 00:01:08,320
so-called therianthrope from the Greek
14
00:01:08,320 --> 00:01:11,160
therion meaning "wild beast"
and anthropos meaning "man."
15
00:01:11,160 --> 00:01:13,440
These are very common entities
that are encountered.
16
00:01:14,880 --> 00:01:18,240
What intrigues me
is that evidence of the use of ayahuasca
17
00:01:18,240 --> 00:01:20,600
and the visions it inspires
18
00:01:20,600 --> 00:01:22,680
can be found not just in the Amazon,
19
00:01:22,680 --> 00:01:26,680
but at many other ancient sites
I've explored in South America.
20
00:01:29,280 --> 00:01:33,400
{\an8}In Cusco, the Inca used the brew
during human sacrifices
21
00:01:34,080 --> 00:01:36,960
to aid the victim's passage
to the afterlife.
22
00:01:38,360 --> 00:01:41,080
And their patterned, figure-filled artwork
23
00:01:41,080 --> 00:01:44,960
greatly resembles
contemporary ayahuasca-inspired art.
24
00:01:46,840 --> 00:01:49,360
{\an8}At the pre-Inca site
of Tiwanaku in Bolivia,
25
00:01:49,960 --> 00:01:53,800
researchers have identified the objects
held by this 1,500-year-old statue
26
00:01:54,720 --> 00:01:57,680
as snuff trays for hallucinogenic powders,
27
00:01:59,120 --> 00:02:02,600
while much Tiwanaku pottery
features geometric designs
28
00:02:02,600 --> 00:02:06,640
and fantastical entities,
likely inspired by psychedelic visions.
29
00:02:08,600 --> 00:02:13,000
You can see those same visions reflected
in traditional Amazonian art too.
30
00:02:15,880 --> 00:02:18,400
What comes to mind
is the case of the Tucano,
31
00:02:18,920 --> 00:02:21,880
who, by and large,
paint on non-permanent media.
32
00:02:23,080 --> 00:02:26,880
The painting, the malocas,
you know, the communal houses.
33
00:02:26,880 --> 00:02:28,840
{\an8}You see that there is a continuity here.
34
00:02:30,920 --> 00:02:35,360
Remember the origin myth of the Tucano
that speaks of their great teachers,
35
00:02:35,360 --> 00:02:37,800
the daughter of the sun
and her companions?
36
00:02:39,520 --> 00:02:42,200
Interestingly, the story doesn't end
37
00:02:42,200 --> 00:02:45,760
with the departure
of those mystical, civilizing heroes.
38
00:02:47,720 --> 00:02:49,080
According to lore,
39
00:02:49,080 --> 00:02:52,240
after ensuring the land
could support the newcomers,
40
00:02:52,240 --> 00:02:55,760
the divine beings left open
a channel of communication
41
00:02:55,760 --> 00:02:58,360
for humans to use whenever there was need.
42
00:02:58,920 --> 00:03:02,880
That channel is the brew
we know today as ayahuasca.
43
00:03:05,480 --> 00:03:09,840
The word ayahuasca means "vine of souls"
in Quechua, the Inca language.
44
00:03:11,160 --> 00:03:14,000
But I believe its use
vastly predates the Inca.
45
00:03:14,760 --> 00:03:16,120
This is where the issue
46
00:03:16,120 --> 00:03:19,600
of this very ancient rock art
becomes interesting.
47
00:03:21,920 --> 00:03:23,520
{\an8} These rock paintings
48
00:03:23,520 --> 00:03:26,280
{\an8}from the part of the Amazon
where the Tucano live today
49
00:03:26,760 --> 00:03:31,200
explore the same themes we see
in all ayahuasca-inspired art.
50
00:03:32,360 --> 00:03:38,240
I can't help observing that
there are similar and connected patterns.
51
00:03:38,240 --> 00:03:40,400
We see therianthropic beings,
52
00:03:40,400 --> 00:03:42,920
beings that are part animal,
part human in form.
53
00:03:42,920 --> 00:03:43,880
Like here?
54
00:03:45,080 --> 00:03:47,200
We see geometric patterns.
55
00:03:47,720 --> 00:03:49,040
We see serpents.
56
00:03:49,040 --> 00:03:50,880
To me this is an extraordinary mystery
57
00:03:50,880 --> 00:03:54,520
that... that the same themes keep coming up
again and again and again.
58
00:03:56,600 --> 00:04:01,480
And yet these images, indisputably,
were created during the last Ice Age.
59
00:04:05,520 --> 00:04:10,520
It suggests that ayahuasca was being used
almost 13,000 years ago.
60
00:04:10,520 --> 00:04:12,920
It's a logical deduction
from looking at the art.
61
00:04:12,920 --> 00:04:14,200
Exactly.
62
00:04:17,000 --> 00:04:20,400
If true, the implications are staggering.
63
00:04:23,560 --> 00:04:26,840
It means those ancient Amazonians
may have already mastered
64
00:04:26,840 --> 00:04:29,080
the complex chemistry of ayahuasca
65
00:04:30,960 --> 00:04:32,560
as far back as the Ice Age.
66
00:04:46,960 --> 00:04:49,880
{\an8}
67
00:04:55,000 --> 00:04:58,080
The geometry,
the spiraling patterns,
68
00:04:58,920 --> 00:05:02,400
this is one of the most extraordinary
aspects of the psychedelic experience.
69
00:05:04,280 --> 00:05:08,080
Those geometric visions may explain
another mystery that we encountered
70
00:05:08,080 --> 00:05:11,240
at the very start
of our exploration of the Americas.
71
00:05:13,800 --> 00:05:16,640
{\an8}The immense geoglyphs
emerging from the jungle
72
00:05:16,640 --> 00:05:19,160
{\an8}along the southwestern rim of the Amazon.
73
00:05:20,880 --> 00:05:24,600
I'm struck by the repetition
of the geometrical idea,
74
00:05:24,600 --> 00:05:27,680
that we find this again and again,
whether the art is modern,
75
00:05:27,680 --> 00:05:30,480
whether it's 13,000 years old,
we find it here.
76
00:05:30,480 --> 00:05:34,080
And I can't help wondering
whether these geometric earthworks
77
00:05:34,080 --> 00:05:36,240
may also have been influenced
by ayahuasca.
78
00:05:36,240 --> 00:05:39,680
Can be. By ayahuasca
or other visionary plants.
79
00:05:39,680 --> 00:05:42,280
- Other plants.
- Because there are many plants.
80
00:05:42,280 --> 00:05:48,120
Behind every, uh, culture you find
some visionary plant of some sort.
81
00:05:50,480 --> 00:05:55,400
Those geoglyphs seem
to be a manifestation
82
00:05:55,400 --> 00:05:59,320
in three-dimensional form,
on an enormous scale,
83
00:05:59,320 --> 00:06:03,880
of precisely the kind of visions
that are induced by the consumption
84
00:06:03,880 --> 00:06:06,280
of a substance like ayahuasca,
85
00:06:06,280 --> 00:06:10,040
where the very first things that are seen
are geometrical patterns.
86
00:06:12,560 --> 00:06:17,200
I think we are seeing a manifestation
of the same impulse in different media.
87
00:06:19,960 --> 00:06:23,920
And if the Amazonian geoglyphs
were inspired by visionary experiences,
88
00:06:24,680 --> 00:06:28,800
then we have to ask where else
that inspiration might have been felt
89
00:06:29,560 --> 00:06:31,560
for one compelling reason.
90
00:06:32,360 --> 00:06:37,200
How similar these earthworks are
to geometrical earthworks
91
00:06:37,200 --> 00:06:40,840
{\an8}in North America, in the state of Ohio.
92
00:06:43,080 --> 00:06:46,160
They're called
the Hopewell Ceremonial Earthworks,
93
00:06:46,160 --> 00:06:50,240
attributed to a civilization
known today as the Hopewell culture
94
00:06:51,040 --> 00:06:55,000
that thrived in the Great Lakes region
around 2,000 years ago.
95
00:06:55,000 --> 00:06:59,440
Massive ditches and embankments
in precise geometrical array.
96
00:07:00,560 --> 00:07:04,000
You could really transpose
the earthworks of the Amazon
97
00:07:04,000 --> 00:07:07,360
to the earthworks of Ohio or vice versa.
98
00:07:09,200 --> 00:07:13,640
And yet they appear to have been created
by completely unconnected cultures.
99
00:07:14,520 --> 00:07:20,000
This is where I simply cannot accept
coincidence as an explanation.
100
00:07:20,000 --> 00:07:24,000
I think that when we see an idea
cropping up again and again
101
00:07:24,000 --> 00:07:26,720
in widely-separated
geographical locations,
102
00:07:28,640 --> 00:07:31,520
{\an8}what we're looking at
is an inheritance of ideas
103
00:07:31,520 --> 00:07:35,880
{\an8}that was passed down and that manifests
in different periods of time.
104
00:07:35,880 --> 00:07:39,160
{\an8}But the idea is what is truly ancient,
105
00:07:39,160 --> 00:07:42,360
not necessarily the structure
that we're looking at.
106
00:07:44,680 --> 00:07:49,160
Unlike their Amazonian counterparts,
where research is only just beginning...
107
00:07:51,200 --> 00:07:55,080
...the earthworks in Ohio have been studied
for more than a century.
108
00:07:56,000 --> 00:08:00,200
And we know they're more
than just intriguing geometrical shapes.
109
00:08:02,840 --> 00:08:06,640
Many of Ohio's earthworks,
including the effigy of Serpent Mound,
110
00:08:07,240 --> 00:08:11,880
feature precise alignments
to specific solstices and equinoxes.
111
00:08:13,840 --> 00:08:16,160
But remarkably, in some cases,
112
00:08:16,160 --> 00:08:18,000
they were built to align directly
113
00:08:18,000 --> 00:08:21,000
with even more
complex lunar cycles as well.
114
00:08:22,520 --> 00:08:26,280
It's one of the curiosities
of the ancient world
115
00:08:26,280 --> 00:08:33,200
that there was a very intense interest
in what was going on in the heavens.
116
00:08:35,280 --> 00:08:38,320
These astounding feats
of astronomical observation
117
00:08:38,320 --> 00:08:41,680
were made by ancient Americans
some 2,000 years ago,
118
00:08:43,080 --> 00:08:44,400
perhaps far earlier,
119
00:08:45,960 --> 00:08:49,240
and can also be found
in other North American mound structures.
120
00:08:51,120 --> 00:08:53,800
{\an8}At sites like the 1,000-year-old Cahokia
121
00:08:55,400 --> 00:08:57,840
{\an8}and 3,000-year-old Poverty Point,
122
00:08:59,160 --> 00:09:02,800
itself purposefully positioned
due north of another site,
123
00:09:03,920 --> 00:09:07,800
{\an8}Lower Jackson Mound,
which dates back 5,000 years.
124
00:09:10,040 --> 00:09:12,800
Who knows what astronomy might lie encoded
125
00:09:12,800 --> 00:09:14,520
waiting to be discovered
126
00:09:14,520 --> 00:09:17,640
in those recently-revealed
Amazonian geoglyphs?
127
00:09:18,720 --> 00:09:22,000
We know that human beings were in America
for tens of thousands of years.
128
00:09:22,000 --> 00:09:25,680
Surely there should be openness
to the possibility that there was time
129
00:09:25,680 --> 00:09:29,280
to develop a culture, to develop
sophisticated knowledge of the heavens,
130
00:09:29,280 --> 00:09:31,480
and to express that in monuments.
131
00:09:33,200 --> 00:09:35,760
Could this
detailed astronomical knowledge
132
00:09:35,760 --> 00:09:39,640
be evidence that the lost civilization
of the Ice Age I'm seeking
133
00:09:39,640 --> 00:09:44,040
left a legacy of ideas
in other parts of North America as well?
134
00:09:53,880 --> 00:09:56,120
1,300 miles from Ohio...
135
00:10:02,240 --> 00:10:04,520
...in the northwest corner of New Mexico,
136
00:10:05,320 --> 00:10:08,000
I've arrived at
a high-altitude cold desert
137
00:10:08,960 --> 00:10:11,760
carved up by towering mesas and buttes.
138
00:10:13,760 --> 00:10:16,680
The Badlands
of the southwestern United States
139
00:10:16,680 --> 00:10:20,240
are a realm of harsh extremes
and breathtaking vistas,
140
00:10:20,840 --> 00:10:22,960
intersected by ancient canyons
141
00:10:22,960 --> 00:10:26,160
with near-vertical sandstone cliffs
on both sides.
142
00:10:30,520 --> 00:10:34,280
You might think that the desolate setting
of these Badlands
143
00:10:34,280 --> 00:10:38,240
would be ill-suited
to any large-scale construction project,
144
00:10:38,240 --> 00:10:40,480
either now or in ancient times.
145
00:10:41,360 --> 00:10:42,720
But you'd be wrong.
146
00:10:44,280 --> 00:10:48,320
This canyon is home to some
of the most important archaeological sites
147
00:10:48,320 --> 00:10:49,280
in North America.
148
00:10:52,320 --> 00:10:54,560
Dozens of ancient man-made structures
149
00:10:54,560 --> 00:10:57,400
are scattered
for miles across the valley floor,
150
00:10:59,080 --> 00:11:01,080
from small freestanding chambers
151
00:11:02,960 --> 00:11:05,440
to massive so-called great houses.
152
00:11:07,440 --> 00:11:09,960
This is Chaco Canyon.
153
00:11:17,280 --> 00:11:19,760
Despite more
than a century of research,
154
00:11:21,080 --> 00:11:25,880
the ancient structures that we see here
in Chaco Canyon remain enigmatic.
155
00:11:26,920 --> 00:11:30,760
Their origins and even their function
are still hotly debated.
156
00:11:36,680 --> 00:11:40,520
At the heart of the mystery
in the center of the canyon...
157
00:11:44,200 --> 00:11:47,480
is the most imposing great house
of them all.
158
00:11:52,360 --> 00:11:56,200
The name of this place is Pueblo Bonito,
meaning "beautiful town."
159
00:11:59,760 --> 00:12:02,040
Rising to a height of several stories,
160
00:12:03,080 --> 00:12:07,160
it's a labyrinth of rooms, corridors,
161
00:12:09,000 --> 00:12:12,720
and vast, circular,
semi-subterranean enclosures.
162
00:12:14,760 --> 00:12:18,120
Even today, centuries after
all work here ceased,
163
00:12:18,120 --> 00:12:20,000
it strikes the eye forcefully.
164
00:12:22,080 --> 00:12:25,600
Pueblo Bonito is
a huge construction project.
165
00:12:27,520 --> 00:12:29,840
Hundreds of rooms have been mapped,
166
00:12:32,160 --> 00:12:37,000
many mysteriously built
with no obvious way in or out.
167
00:12:39,880 --> 00:12:42,400
Archaeologists have worked here
for decades
168
00:12:42,400 --> 00:12:44,560
and made many significant discoveries.
169
00:12:45,720 --> 00:12:48,160
Yet it still confounds interpretation.
170
00:12:52,080 --> 00:12:54,680
But one thing we can be fairly certain of
171
00:12:54,680 --> 00:12:57,880
is how Pueblo Bonito
would have looked in its prime.
172
00:13:01,040 --> 00:13:03,680
The compound was a huge semicircle
173
00:13:04,320 --> 00:13:07,520
with straight walls
facing the canyon floor.
174
00:13:08,640 --> 00:13:13,200
Rectangular buildings were stacked
around the curve, four stories tall,
175
00:13:15,760 --> 00:13:18,160
creating as many as 800 rooms,
176
00:13:18,680 --> 00:13:22,400
all surrounding a plaza
divided by a central wall
177
00:13:23,000 --> 00:13:27,320
with multiple circular,
semi-subterranean structures on each side.
178
00:13:30,800 --> 00:13:33,000
So who were its builders?
179
00:13:33,000 --> 00:13:36,360
And why did they go
to such immense lengths
180
00:13:36,360 --> 00:13:39,200
to create this extraordinary edifice?
181
00:13:43,440 --> 00:13:44,840
Nathan Hatfield,
182
00:13:44,840 --> 00:13:48,920
{\an8}officially designated as
Chaco Canyon's Chief of Interpretation,
183
00:13:49,480 --> 00:13:52,160
has spent nearly a decade
studying the structures here.
184
00:13:56,240 --> 00:13:58,440
Tell us about the place
that we're standing in.
185
00:13:59,120 --> 00:14:03,200
This structure was the largest building
in North America
186
00:14:03,200 --> 00:14:06,360
up until the mid-19th century.
187
00:14:09,440 --> 00:14:12,640
Archaeologists couldn't
carbon date the stone itself.
188
00:14:13,920 --> 00:14:16,960
But using the highly accurate
tree-ring method of dating
189
00:14:16,960 --> 00:14:18,560
on its wooden beams,
190
00:14:18,560 --> 00:14:22,080
they were able to determine
various phases of construction.
191
00:14:24,000 --> 00:14:26,520
This was not built in a single moment.
192
00:14:26,520 --> 00:14:29,800
This was built over a period
of a couple of centuries.
193
00:14:29,800 --> 00:14:32,680
So if we look at that oldest part
of Pueblo Bonito,
194
00:14:32,680 --> 00:14:34,880
what sort of numbers are we talking about?
195
00:14:34,880 --> 00:14:37,240
It was built starting around 850.
196
00:14:37,840 --> 00:14:39,720
- That's 850 AD?
- 850 AD.
197
00:14:39,720 --> 00:14:40,640
Yeah.
198
00:14:41,160 --> 00:14:44,680
And construction was ongoing for
199
00:14:44,680 --> 00:14:47,360
at least 200 years,
maybe a little bit longer.
200
00:14:48,000 --> 00:14:50,040
This was before
the area was settled
201
00:14:50,040 --> 00:14:51,800
by the modern-day Pueblo peoples...
202
00:14:53,960 --> 00:14:56,680
like the Hopi, the Zuni, and the Acoma.
203
00:14:59,880 --> 00:15:02,720
Pueblo Bonito was built by
204
00:15:02,720 --> 00:15:05,040
what we call the ancestral Pueblo people.
205
00:15:05,040 --> 00:15:06,880
- For reasons unknown to us...
- Yeah.
206
00:15:06,880 --> 00:15:12,040
...they selected Chaco Canyon
to be the center of their culture.
207
00:15:12,840 --> 00:15:17,520
And Pueblo Bonito would become
the largest building
208
00:15:17,520 --> 00:15:19,520
in this cultural center.
209
00:15:21,280 --> 00:15:24,600
A cultural center that,
as well as Pueblo Bonito,
210
00:15:24,600 --> 00:15:27,360
featured more
than a dozen other great houses.
211
00:15:29,400 --> 00:15:34,080
Why did they build all these structures
here in Chaco Canyon?
212
00:15:35,760 --> 00:15:39,640
Was there a permanent
established residential population here?
213
00:15:40,280 --> 00:15:43,560
No. Archaeologists did not see
214
00:15:43,560 --> 00:15:46,920
the evidence to support a huge population.
215
00:15:49,000 --> 00:15:54,080
So if these great houses
weren't actually built to house people,
216
00:15:54,720 --> 00:15:56,080
what was their purpose?
217
00:15:59,520 --> 00:16:04,440
Within the ruins, archaeologists found
more than a hundred ritual burials...
218
00:16:08,440 --> 00:16:12,680
along with pottery
featuring spectacular geometric patterns
219
00:16:13,880 --> 00:16:19,000
{\an8}and artifacts known to come from hundreds,
if not thousands, of miles away.
220
00:16:20,360 --> 00:16:23,960
{\an8}We find that enormous efforts
were gone to...
221
00:16:24,840 --> 00:16:27,880
to create it
as a kind of center of the world.
222
00:16:31,120 --> 00:16:33,760
As the evidence has come in,
it's become clear that
223
00:16:33,760 --> 00:16:36,680
it seems to have been
a center of pilgrimage,
224
00:16:36,680 --> 00:16:39,720
where people would come
from all directions,
225
00:16:39,720 --> 00:16:41,800
drawn to the magic of the place.
226
00:16:42,960 --> 00:16:45,720
It clearly is a sacred place of some sort.
227
00:16:48,880 --> 00:16:51,760
In that light,
the circular structures we find
228
00:16:51,760 --> 00:16:55,640
within nearly all of Chaco's buildings
make more sense.
229
00:16:56,800 --> 00:17:00,160
The Hopi,
descendants of the ancestral Puebloans,
230
00:17:00,160 --> 00:17:02,720
call such structures kivas.
231
00:17:03,880 --> 00:17:05,240
Tell me about the kivas.
232
00:17:05,240 --> 00:17:08,320
What is your understanding
of what they were and are?
233
00:17:08,920 --> 00:17:12,800
It's generally agreed upon
that a kiva was a ceremonial space.
234
00:17:12,800 --> 00:17:15,200
There are features that are pretty common.
235
00:17:15,720 --> 00:17:17,200
There's the bench.
236
00:17:17,200 --> 00:17:20,760
Within the larger great kivas,
you see floor vaults.
237
00:17:20,760 --> 00:17:24,880
Most of them have
some kind of wood-burning fireplace.
238
00:17:26,360 --> 00:17:28,880
For the Hopi
and Pueblo peoples today,
239
00:17:28,880 --> 00:17:32,760
the kiva is a spiritual
and political space
240
00:17:32,760 --> 00:17:35,800
in which they gather
to perform sacred rituals.
241
00:17:35,800 --> 00:17:37,800
So it's
an ongoing cultural tradition?
242
00:17:37,800 --> 00:17:40,200
- And they're used for ceremony?
- Yes. Yes.
243
00:17:41,080 --> 00:17:43,720
Ceremonies that, then and now,
244
00:17:43,720 --> 00:17:46,920
feature the consumption
of a special form of tobacco.
245
00:17:49,000 --> 00:17:50,960
{\an8}North of Chaco in Utah,
246
00:17:51,600 --> 00:17:54,960
archaeologists studying
an ancient man-made hearth
247
00:17:54,960 --> 00:17:57,560
found seeds
from the hallucinogenic species
248
00:17:58,280 --> 00:17:59,520
coyote tobacco.
249
00:18:00,520 --> 00:18:04,320
The seeds were carbon-dated
to 12,300 years ago,
250
00:18:05,000 --> 00:18:07,120
suggesting humans were using tobacco here
251
00:18:07,120 --> 00:18:09,080
as far back as the Ice Age.
252
00:18:09,800 --> 00:18:12,680
It's likely that
such hallucinogenic plants
253
00:18:12,680 --> 00:18:17,040
were still in use thousands of years later
in ceremonies here at Chaco...
254
00:18:19,520 --> 00:18:22,320
just as shamans
of the Amazon use ayahuasca.
255
00:18:25,920 --> 00:18:29,000
Is it possible
that these shamanistic traditions,
256
00:18:29,000 --> 00:18:31,080
thousands of miles apart,
257
00:18:31,600 --> 00:18:34,920
are the legacy of a single,
more ancient belief system
258
00:18:34,920 --> 00:18:37,760
that left traces of itself
across the Americas?
259
00:18:39,440 --> 00:18:42,640
To explore the mysteries
of these kivas further,
260
00:18:42,640 --> 00:18:47,800
I'm headed to the canyon rim,
about half a mile south of Pueblo Bonito,
261
00:18:49,080 --> 00:18:50,920
to the grandest kiva of them all...
262
00:18:52,760 --> 00:18:54,080
...Casa Rinconada.
263
00:18:57,840 --> 00:19:00,480
Unlike the vast majority of Chaco's kivas,
264
00:19:00,480 --> 00:19:03,880
Casa Rinconada stands apart
from any other extensive building.
265
00:19:06,080 --> 00:19:08,040
Inside the sunken enclosure,
266
00:19:08,040 --> 00:19:11,160
T-shaped doorways
are positioned in the walls,
267
00:19:11,880 --> 00:19:15,280
openings that face
almost perfectly north and south.
268
00:19:17,640 --> 00:19:21,760
As time-lapse photos show,
directly above the doorway,
269
00:19:21,760 --> 00:19:25,600
the night sky revolves around
the north star Polaris.
270
00:19:27,840 --> 00:19:31,400
There's something strangely familiar
about Casa Rinconada.
271
00:19:33,560 --> 00:19:37,120
{\an8}It reminds me of the Ice Age
megalithic site of Göbekli Tepe
272
00:19:37,120 --> 00:19:38,440
{\an8}in far-off Turkey.
273
00:19:40,720 --> 00:19:44,360
There, similarly sunken,
circular, kiva-like chambers
274
00:19:45,160 --> 00:19:46,720
feature T-shaped pillars,
275
00:19:47,360 --> 00:19:50,600
which too are aligned
to specific points in the heavens.
276
00:19:53,200 --> 00:19:55,320
But how could these ancient structures,
277
00:19:55,320 --> 00:19:58,880
so widely separated by geography and time,
278
00:19:59,400 --> 00:20:00,680
have any connection?
279
00:20:01,520 --> 00:20:03,360
It's tempting to speculate.
280
00:20:04,440 --> 00:20:07,960
And the origin myth of the Hopi
offers a possible clue.
281
00:20:09,200 --> 00:20:12,320
The Hopi believe
that we're living in the fourth world,
282
00:20:12,320 --> 00:20:15,560
that there have been
three previous emergences
283
00:20:15,560 --> 00:20:18,080
from some sort of underground realm.
284
00:20:22,920 --> 00:20:26,880
According to Hopi legend,
after creating the first living creatures,
285
00:20:27,440 --> 00:20:30,840
the sun spirit ordered his messenger,
Spider Grandmother,
286
00:20:31,440 --> 00:20:35,760
to guide these ever-evolving life forms
through the first two worlds.
287
00:20:38,720 --> 00:20:39,920
In the third world,
288
00:20:39,920 --> 00:20:43,080
she showed early humans
how to weave and make pottery
289
00:20:43,800 --> 00:20:45,800
and taught them good from evil.
290
00:20:49,440 --> 00:20:52,000
Still, some turned
to wicked ways.
291
00:20:54,760 --> 00:20:57,000
Displeased,
the sun spirit ordered
292
00:20:57,000 --> 00:20:59,120
those of good heart to move on.
293
00:21:00,960 --> 00:21:04,280
They ascended a great reed
to an opening in the sky.
294
00:21:05,560 --> 00:21:09,040
There, Spider Grandmother
helped them emerge into their new home,
295
00:21:09,640 --> 00:21:13,320
the fourth world,
where their descendants still live today.
296
00:21:16,840 --> 00:21:20,280
The Hopi hold sacred
an unusual geological feature
297
00:21:20,280 --> 00:21:21,640
in the Grand Canyon,
298
00:21:22,160 --> 00:21:25,360
believing it to be
the literal emergence point of myth.
299
00:21:26,680 --> 00:21:28,320
They call it Sipapu.
300
00:21:30,040 --> 00:21:31,400
No one is allowed near it,
301
00:21:31,400 --> 00:21:34,920
but symbolically, it's replicated
throughout the Hopi world.
302
00:21:38,000 --> 00:21:43,880
In Puebloan culture, a hole in the floor
of the kiva is also known as a sipapu,
303
00:21:43,880 --> 00:21:49,000
and this is seen as the place from which
the ancients emerged from a previous world
304
00:21:49,000 --> 00:21:53,120
that had been destroyed
into the world that we live in today.
305
00:21:54,280 --> 00:21:57,040
And this is where
I want to make a comparison
306
00:21:57,040 --> 00:21:59,440
that might seem very extreme.
307
00:21:59,440 --> 00:22:04,080
I'm just wondering
whether it all goes back to a time
308
00:22:04,080 --> 00:22:08,000
when it was necessary
for people to take shelter underground.
309
00:22:08,640 --> 00:22:13,360
And we know that there was such a time
around 12,800 years ago
310
00:22:13,360 --> 00:22:15,400
at the beginning of the Younger Dryas.
311
00:22:17,520 --> 00:22:19,320
Although still debated,
312
00:22:19,320 --> 00:22:22,560
many scientists believe
that the Earth-shaking cataclysms
313
00:22:22,560 --> 00:22:28,400
and floods of that time were caused
by cosmic impacts and airbursts
314
00:22:28,400 --> 00:22:30,600
as the Earth passed through
the debris trail
315
00:22:30,600 --> 00:22:32,680
of a disintegrating comet.
316
00:22:35,600 --> 00:22:38,440
If the enemy was danger from the sky,
317
00:22:38,440 --> 00:22:42,040
if we're looking at impacts
from a fragmenting giant comet,
318
00:22:42,040 --> 00:22:45,000
uh, then underground structures
make a great deal of sense.
319
00:22:45,920 --> 00:22:48,840
That deep ancient connection
is not a direct connection.
320
00:22:48,840 --> 00:22:51,640
It's a stored memory in oral tradition
321
00:22:52,200 --> 00:22:55,760
that there was a time
when our ancestors had to emerge
322
00:22:55,760 --> 00:22:58,760
from beneath the ground
to come out into a new world
323
00:22:58,760 --> 00:23:03,160
that had been swept clean in a cataclysm
and to repopulate that new world.
324
00:23:06,080 --> 00:23:07,360
Let me be clear.
325
00:23:07,360 --> 00:23:12,000
I don't doubt that this spectacular kiva
dates from around 1,000 years ago,
326
00:23:12,000 --> 00:23:14,960
but I suspect
that its builders incorporated within it
327
00:23:14,960 --> 00:23:19,200
a legacy of knowledge and ideas
that are far, far older.
328
00:23:20,480 --> 00:23:24,200
Much like another idea
we see demonstrated again and again
329
00:23:24,200 --> 00:23:26,520
at all these ancient American sites,
330
00:23:27,320 --> 00:23:30,920
the importance of astronomical
and geometrical knowledge.
331
00:23:34,320 --> 00:23:38,680
At Pueblo Bonito,
the whole structure is perfectly aligned
332
00:23:38,680 --> 00:23:42,840
to the cardinal directions,
north, south, east, and west,
333
00:23:43,600 --> 00:23:47,200
showing its builders understood
their place on the planet.
334
00:23:48,200 --> 00:23:52,640
What's more, on the equinox,
something magical happens.
335
00:23:53,320 --> 00:23:58,240
The sun rises and sets perfectly in line
with the west side of the southern wall.
336
00:24:00,480 --> 00:24:02,800
It wasn't
just some random accident.
337
00:24:03,480 --> 00:24:05,080
It was so well-thought-out.
338
00:24:05,680 --> 00:24:08,920
And what's, I think,
appealing to people about that
339
00:24:08,920 --> 00:24:11,680
is that it's the same sky
that we can see today.
340
00:24:11,680 --> 00:24:13,680
- Yes.
- We can still see the alignments.
341
00:24:16,080 --> 00:24:20,320
I've heard that there were functionaries
called sun priests here in the past.
342
00:24:20,320 --> 00:24:21,400
Is that right?
343
00:24:21,400 --> 00:24:24,880
They were the sun watchers,
the sun priests.
344
00:24:24,880 --> 00:24:27,640
They were people dedicated
to the architecture.
345
00:24:27,640 --> 00:24:30,760
There were people dedicated
to watching the sky.
346
00:24:30,760 --> 00:24:31,680
Yeah.
347
00:24:33,360 --> 00:24:37,040
What were the main celestial events
that they were tracking?
348
00:24:37,040 --> 00:24:41,400
Summer solstice, winter solstice,
equinoxes, when the sun rises due east?
349
00:24:41,400 --> 00:24:43,920
That ties back to the agriculture.
350
00:24:43,920 --> 00:24:45,000
Right.
351
00:24:45,000 --> 00:24:50,720
Having that calendar on the landscape
is critical for survival.
352
00:24:50,720 --> 00:24:53,640
And the fact
that they were able to do that
353
00:24:53,640 --> 00:24:56,360
with these monumental structures,
354
00:24:56,960 --> 00:25:01,800
I think it all goes back to their ability
to find success with farming.
355
00:25:03,720 --> 00:25:05,920
It's an argument
I've heard before,
356
00:25:05,920 --> 00:25:07,600
but there's a problem with assuming
357
00:25:07,600 --> 00:25:10,560
all this effort
had to do only with farming.
358
00:25:13,560 --> 00:25:18,600
Around 90 miles north of Chaco Canyon
stands a distinctive sandstone ridge
359
00:25:19,240 --> 00:25:24,240
topped by two pinnacles known as
Chimney Rock and Companion Rock.
360
00:25:25,960 --> 00:25:30,640
Near them, we find a Chacoan great house
complete with two kivas.
361
00:25:31,760 --> 00:25:37,120
It turns out
that that whole structure was placed there
362
00:25:37,120 --> 00:25:39,280
in a very precise alignment
363
00:25:39,280 --> 00:25:45,880
to allow observation of a lunar event
that only occurs once every 18.6 years,
364
00:25:45,880 --> 00:25:48,920
and that is the extreme
northern standstill of the moon.
365
00:25:50,320 --> 00:25:52,480
It's when the rising and setting moon
366
00:25:52,480 --> 00:25:55,480
reaches its most northerly point
in the night sky
367
00:25:56,080 --> 00:25:58,960
before appearing to rise
and set further south
368
00:25:58,960 --> 00:26:00,760
as part of a recurring cycle.
369
00:26:02,520 --> 00:26:07,000
The moon rises between Chimney Rock
and Companion Rock
370
00:26:07,000 --> 00:26:09,720
only at that time and at no other time.
371
00:26:11,480 --> 00:26:14,520
This is the kind of knowledge
that has to be handed down
372
00:26:14,520 --> 00:26:16,120
generation to generation.
373
00:26:16,960 --> 00:26:18,760
You don't just notice it once
374
00:26:18,760 --> 00:26:21,200
and then build a structure
to memorialize it.
375
00:26:23,880 --> 00:26:27,080
It speaks to
an ancient intellectual endeavor
376
00:26:27,080 --> 00:26:30,280
to understand the cosmos
that surrounds us,
377
00:26:30,280 --> 00:26:34,960
and that cosmos is full
of motion and changes,
378
00:26:35,640 --> 00:26:38,720
and the long-term observation
of those motions and changes
379
00:26:38,720 --> 00:26:41,360
requires a really dedicated effort,
380
00:26:41,360 --> 00:26:43,520
in many cases over thousands of years.
381
00:26:46,400 --> 00:26:49,200
Once researchers started looking
for lunar alignments
382
00:26:49,200 --> 00:26:51,440
in the buildings in Chaco Canyon,
383
00:26:51,440 --> 00:26:54,080
all sorts of remarkable examples
were found.
384
00:26:56,560 --> 00:27:00,960
When the moon reaches
its extreme southern standstill in winter,
385
00:27:00,960 --> 00:27:03,800
again once every 18.6 years,
386
00:27:04,640 --> 00:27:08,640
{\an8}it rises in a line
through three great houses six miles apart
387
00:27:09,160 --> 00:27:11,160
{\an8}with Pueblo Bonito at its middle.
388
00:27:12,160 --> 00:27:15,960
{\an8}And 9.3 years later,
at the halfway point in this cycle,
389
00:27:16,640 --> 00:27:20,000
the summer moon rises in a line
across a large structure
390
00:27:20,000 --> 00:27:25,080
{\an8}just east of Pueblo Bonito
to another one 11 miles to the southwest...
391
00:27:27,640 --> 00:27:31,760
while that same setting moon
shines across one great house,
392
00:27:31,760 --> 00:27:33,880
again through Pueblo Bonito,
393
00:27:33,880 --> 00:27:38,560
more than 17 miles beyond the canyon
to yet another great house.
394
00:27:40,200 --> 00:27:41,800
And one thing is certain.
395
00:27:42,320 --> 00:27:47,000
The 18.6-year lunar cycle
has no influence whatsoever
396
00:27:47,560 --> 00:27:49,240
on the growing of crops.
397
00:27:49,240 --> 00:27:51,840
Why, therefore, did the ancient Puebloans
398
00:27:51,840 --> 00:27:55,120
go to such lengths
to mark it in their architecture?
399
00:27:56,880 --> 00:28:01,000
That speaks eloquently to the fact
that no economic purpose was involved,
400
00:28:01,000 --> 00:28:03,160
that this was about the celebration
401
00:28:03,160 --> 00:28:05,200
of the connection
between heaven and earth.
402
00:28:07,320 --> 00:28:11,520
What's now clear is
that all these Chacoan structures combine
403
00:28:11,520 --> 00:28:14,880
to form a ritual calendar
laid out upon the Earth...
404
00:28:18,480 --> 00:28:21,920
...in a canyon that may have been chosen
for this very purpose
405
00:28:22,440 --> 00:28:25,120
as a terrestrial counterpart
to the Milky Way.
406
00:28:27,680 --> 00:28:32,480
But the connections with the cosmos,
sky and ground, as above, so below,
407
00:28:33,240 --> 00:28:35,320
that were so important to Chaco culture
408
00:28:35,320 --> 00:28:38,520
aren't limited
to its vast building complexes.
409
00:28:42,000 --> 00:28:44,880
About five miles southeast
of central Chaco...
410
00:28:47,280 --> 00:28:49,320
I'm heading up from the canyon floor
411
00:28:51,080 --> 00:28:55,800
in search of something intriguing
that adorns these rugged canyon walls.
412
00:28:59,360 --> 00:29:04,240
Ancient works of art
carved into the living rock.
413
00:29:09,800 --> 00:29:13,000
These are precious records,
stories in stone
414
00:29:13,000 --> 00:29:16,480
that have been continually revised,
altered, and added to
415
00:29:16,480 --> 00:29:19,440
over who knows
how many thousands of years.
416
00:29:21,720 --> 00:29:24,480
There are human figures
that appear to be dancing
417
00:29:24,480 --> 00:29:26,560
and playing musical instruments.
418
00:29:29,000 --> 00:29:32,800
Spirals and serpents coil
along the canyon walls,
419
00:29:33,440 --> 00:29:37,640
which also feature
strange creatures and geometric forms,
420
00:29:37,640 --> 00:29:40,400
much like those that appear
in artwork of the Amazon,
421
00:29:40,920 --> 00:29:42,920
possibly inspired by psychedelics.
422
00:29:44,880 --> 00:29:48,320
Whichever part of the world you're in
and whichever period of history it is,
423
00:29:48,320 --> 00:29:51,920
once you come to the cave art
and the petroglyphs and the rock art,
424
00:29:51,920 --> 00:29:55,200
you find again and again
exactly the same visuals
425
00:29:55,200 --> 00:29:57,600
that you find
with the ayahuasca experience
426
00:29:57,600 --> 00:29:59,440
and other psychedelics being repeated.
427
00:30:02,840 --> 00:30:05,200
As well as these visionary elements,
428
00:30:05,200 --> 00:30:10,360
Chacoan rock art reflects the same focus
on astronomy found in its architecture.
429
00:30:13,320 --> 00:30:16,480
This image has been interpreted
as an eclipse,
430
00:30:17,240 --> 00:30:21,320
the sun darkened by the moon,
while its corona flares outwards.
431
00:30:23,600 --> 00:30:25,840
And this, a supernova,
432
00:30:25,840 --> 00:30:28,880
now known to have been visible
in the daytime sky
433
00:30:29,480 --> 00:30:33,680
during the ancestral Puebloan period
in AD 1054.
434
00:30:34,680 --> 00:30:38,600
Why create such imagery
in such a hard-to-reach location
435
00:30:39,120 --> 00:30:41,680
unless there was
a compelling reason to do so?
436
00:30:43,200 --> 00:30:48,640
In the absence of any apparent economic,
strategic, or political motive,
437
00:30:48,640 --> 00:30:52,280
it follows that some higher purpose
must have been involved.
438
00:30:53,560 --> 00:30:56,000
It seems to me more and more obvious
439
00:30:56,000 --> 00:30:59,440
that Chaco Canyon
is a ritualized landscape
440
00:30:59,440 --> 00:31:03,880
and that its origins can't be limited
to a mere thousand or so years ago,
441
00:31:03,880 --> 00:31:05,880
but must go back much further,
442
00:31:05,880 --> 00:31:08,360
perhaps even as far back
as the last Ice Age.
443
00:31:13,920 --> 00:31:18,600
To your knowledge,
how far back in the past can we trace
444
00:31:18,600 --> 00:31:21,280
any kind of human presence
here in Chaco Canyon?
445
00:31:21,280 --> 00:31:25,880
You've probably heard very recently
in White Sands National Monument--
446
00:31:25,880 --> 00:31:28,280
23,000-year-old footprints in White Sands.
447
00:31:28,280 --> 00:31:30,840
- And that's not that far away.
- No.
448
00:31:30,840 --> 00:31:35,120
So it's quite likely that people
would have been in Chaco Canyon
449
00:31:35,800 --> 00:31:37,160
maybe even...
450
00:31:37,160 --> 00:31:40,680
maybe even 10,000 years before
any building was constructed.
451
00:31:43,040 --> 00:31:45,080
I think they were
452
00:31:45,080 --> 00:31:50,280
observing the landscape
and the sky for generations
453
00:31:50,280 --> 00:31:52,880
- before they decided to build.
- Yeah.
454
00:31:57,440 --> 00:31:59,480
Chaco Canyon bears the fingerprints
455
00:31:59,480 --> 00:32:02,840
of a culture
of highly-sophisticated astronomers.
456
00:32:03,720 --> 00:32:09,000
Their intense focus on
the regular cycles of sun, moon, and stars
457
00:32:09,960 --> 00:32:12,360
and on the wider majesty of the cosmos
458
00:32:12,360 --> 00:32:15,320
wasn't just an idiosyncratic quirk
of their own.
459
00:32:15,320 --> 00:32:17,480
It was shared in the same way,
460
00:32:17,480 --> 00:32:22,440
using eerily similar symbolism,
art, and architectural alignments
461
00:32:22,440 --> 00:32:25,560
by many other ancient cultures
all around the world.
462
00:32:27,600 --> 00:32:31,840
{\an8}The way Malta's megalithic
Temple of Mnajdra is precisely aligned
463
00:32:31,840 --> 00:32:34,360
{\an8}to capture the equinoxes
and the solstices.
464
00:32:36,480 --> 00:32:39,560
{\an8}Or how the axis
of the great Temple of Karnak in Egypt
465
00:32:39,560 --> 00:32:41,880
{\an8}targets the winter solstice sunrise.
466
00:32:44,400 --> 00:32:47,480
{\an8}Or the precision
with which the central tower
467
00:32:47,480 --> 00:32:49,560
{\an8}of Angkor Wat in Cambodia
468
00:32:49,560 --> 00:32:52,160
aligns to the rising sun on the equinoxes.
469
00:32:53,480 --> 00:32:57,000
There seems to have been
a worldwide architectural project
470
00:32:57,000 --> 00:33:01,400
to reproduce the harmony
and directions of the heavens
471
00:33:01,400 --> 00:33:05,280
in monuments on the ground
to bring heaven down to earth.
472
00:33:08,240 --> 00:33:12,680
But how far back does
this seemingly global human project go?
473
00:33:19,400 --> 00:33:20,360
There are clues
474
00:33:20,360 --> 00:33:23,880
in one of ancient America's
most accomplished civilizations
475
00:33:26,280 --> 00:33:30,040
that once dominated what is now
southern Mexico and Central America.
476
00:33:31,560 --> 00:33:32,520
The Maya.
477
00:33:35,000 --> 00:33:39,080
The Maya to me are one
of the most fascinating cultures
478
00:33:39,080 --> 00:33:40,480
of the ancient world
479
00:33:41,240 --> 00:33:45,360
and a culture filled with
mystery and contradiction.
480
00:33:48,000 --> 00:33:50,640
Many descendants of the Maya
still live here today
481
00:33:52,440 --> 00:33:56,280
in the spectacular landscapes
of Chiapas and the Yucatán Peninsula.
482
00:34:00,120 --> 00:34:03,600
Here, long before the Incas
and the Pueblo culture of Chaco,
483
00:34:05,160 --> 00:34:07,400
the Maya civilization thrived.
484
00:34:09,240 --> 00:34:12,760
It was a culture
that expressed its genius in many ways,
485
00:34:14,520 --> 00:34:17,960
notably through magnificent feats
of architecture.
486
00:34:20,560 --> 00:34:23,520
Surrounded by dense lowland rainforest,
487
00:34:23,520 --> 00:34:27,400
this is the Mayan sacred realm
of Palenque.
488
00:34:40,040 --> 00:34:43,400
Palenque is
an absolutely breathtaking place.
489
00:34:44,240 --> 00:34:46,560
With its awe-inspiring architecture
and engineering,
490
00:34:46,560 --> 00:34:49,360
it has all the hallmarks
of a classic Mayan site.
491
00:34:52,560 --> 00:34:53,560
Soaring pyramids,
492
00:34:55,600 --> 00:34:57,040
a ceremonial ball court,
493
00:34:58,240 --> 00:34:59,440
a looming palace,
494
00:35:00,840 --> 00:35:04,240
and temples filled
with intriguing imagery.
495
00:35:06,760 --> 00:35:10,000
The Maya are probably best known
for their incredible architecture,
496
00:35:10,000 --> 00:35:14,040
for the amazing complexes
of pyramids that they created,
497
00:35:14,040 --> 00:35:18,920
typically step pyramids,
and the beautiful elegance of the design
498
00:35:18,920 --> 00:35:21,480
and the high precision of the workmanship.
499
00:35:21,480 --> 00:35:24,880
That immediately tells us that
we're dealing with an advanced culture.
500
00:35:29,720 --> 00:35:32,800
{\an8} Maya expert and guide
Mildred Lucas Garcia
501
00:35:32,800 --> 00:35:35,000
{\an8}has devoted more than a decade
502
00:35:35,000 --> 00:35:37,040
to understanding Palenque better.
503
00:35:38,800 --> 00:35:41,080
When did work begin here?
504
00:35:41,600 --> 00:35:43,520
How long was this site occupied?
505
00:35:44,160 --> 00:35:47,600
The city's foundation started
in the year 200 BC,
506
00:35:47,600 --> 00:35:50,640
and it was abandoned over the 900s AD.
507
00:35:50,640 --> 00:35:51,560
Right.
508
00:35:51,560 --> 00:35:55,080
When I look at this incredible site,
these huge pyramids,
509
00:35:55,080 --> 00:35:58,040
beautifully constructed,
beautifully designed,
510
00:35:58,040 --> 00:36:01,360
it's clear that this was the work
of very skillful people,
511
00:36:01,360 --> 00:36:04,600
and that they must have had
some kind of plan from the beginning.
512
00:36:04,600 --> 00:36:06,400
But tell me, how did they do it?
513
00:36:06,400 --> 00:36:09,480
We know
that there were quarries nearby.
514
00:36:09,480 --> 00:36:12,760
That's why they decided to build
the city here
515
00:36:12,760 --> 00:36:15,240
because they had
all the natural resources,
516
00:36:15,240 --> 00:36:17,360
they had all the limestone in this area,
517
00:36:17,360 --> 00:36:19,440
they had the water,
518
00:36:19,440 --> 00:36:23,000
and this was a very strategic area
to build the city.
519
00:36:23,000 --> 00:36:26,720
But how... how they built that,
that's unknown.
520
00:36:26,720 --> 00:36:28,720
- We don't know.
- It's still a mystery.
521
00:36:28,720 --> 00:36:30,640
- It's still a mystery. Mm-hmm.
- Yeah. Yeah.
522
00:36:31,320 --> 00:36:33,800
Why did the Maya build pyramids?
523
00:36:33,800 --> 00:36:36,560
Here in Palenque,
we see a lot of... a lot of pyramids.
524
00:36:37,600 --> 00:36:40,720
The pyramids,
not only for the Mayas,
525
00:36:40,720 --> 00:36:42,600
but for the ancient cultures,
526
00:36:42,600 --> 00:36:44,680
represented the holy mountains.
527
00:36:45,400 --> 00:36:48,440
Here in Palenque,
they built such big structures
528
00:36:48,440 --> 00:36:50,320
to represent these holy mountains.
529
00:36:53,600 --> 00:36:55,600
Mountains played
an important role
530
00:36:55,600 --> 00:36:59,960
in the belief system of the Maya
as symbols of the source of creation.
531
00:37:02,800 --> 00:37:07,160
But it appears that there may have been
more to the Maya's epic building project,
532
00:37:07,160 --> 00:37:09,240
especially here at Palenque.
533
00:37:11,480 --> 00:37:14,760
In Palenque,
some of the buildings were designed
534
00:37:14,760 --> 00:37:17,640
following the astronomical observations.
535
00:37:17,640 --> 00:37:18,600
Wow.
536
00:37:19,720 --> 00:37:22,760
There's three buildings
known as the Group of the Crosses
537
00:37:22,760 --> 00:37:26,600
that were used
as an astronomical observation area.
538
00:37:26,600 --> 00:37:27,560
Right.
539
00:37:28,560 --> 00:37:31,360
These buildings
were perfectly aligned
540
00:37:31,360 --> 00:37:32,920
with the summer solstice...
541
00:37:32,920 --> 00:37:35,360
- Yeah.
- ...and with the spring equinox.
542
00:37:37,680 --> 00:37:41,320
Clearly, highly-skilled astronomers
were involved in the creation
543
00:37:41,320 --> 00:37:42,440
of the whole complex.
544
00:37:42,440 --> 00:37:43,440
Yes, it's true.
545
00:37:47,240 --> 00:37:49,480
But why would they go
to so much trouble
546
00:37:49,480 --> 00:37:51,440
to align these massive structures
547
00:37:51,440 --> 00:37:53,040
to solstices and equinoxes?
548
00:37:57,360 --> 00:38:01,360
Given these incredible alignments,
one thing is clear.
549
00:38:03,360 --> 00:38:06,600
If you want to know
what Palenque is really all about,
550
00:38:06,600 --> 00:38:09,040
you have to look
not only at its architecture,
551
00:38:09,040 --> 00:38:11,080
but also at the sky.
552
00:38:20,640 --> 00:38:26,400
I've come to the Temple of the Sun
at a special moment on a special day,
553
00:38:28,240 --> 00:38:29,840
dawn on the spring equinox,
554
00:38:31,120 --> 00:38:36,520
when the sun rises precisely due east
and sets precisely due west
555
00:38:37,120 --> 00:38:39,680
in a manifestation of cosmic harmony.
556
00:38:41,160 --> 00:38:46,200
Here at the Temple of the Sun,
that sunrise creates a unique spectacle,
557
00:38:46,760 --> 00:38:49,920
one still celebrated today
by the local community.
558
00:38:50,880 --> 00:38:54,080
{\an8}The spring equinox, it is important
559
00:38:54,080 --> 00:38:56,120
{\an8}for the spirituality of the Maya.
560
00:38:56,720 --> 00:39:00,560
Right here where we are
is the most important place.
561
00:39:02,760 --> 00:39:05,240
And I have
a front row seat for it.
