Mystic Places part 5: Teotihuacan: Teotihuacan means 'The City of the Gods", or "Where Men Become Gods" (in Nahuatl). It is located in the valley of the same name 30 miles north of Mexico City. Teotihuacan Location: 19° 40' N 98° 52' W Image courtesy of the GoogleEarth The above satellite image of ancient ruins of Teotihuacan has been generated by Teotihuacan used to be a thriving city and ceremonial center that predated the Aztecs by several centuries. Most likely it was Mexico's biggest ancient city at its peak and the sixth largest city in the world in AD 600. Teotihuacan began declining sharply around 650 AD, and was almost completely abandoned around 750 AD. No one knows why. At its peak around 500-600 A.D., Teotihuacan contained perhaps 200,000 people. It was a well planned city covering nearly eight square miles and larger and more advanced than any European city of the time. Its civilization was contemporary with that of ancient Rome , and lasted longer - more than 500 years. Though archaeologists have long been fascinated with the site, Teotihuacan's culture and history are still largely mysterious. The civilization left massive ruins, but no trace has yet been found of a writing system and very little is known for sure about its inhabitants, who were succeeded first by the Toltecs and then by the Aztecs. The Aztecs did not live in the city, but gave the place and its major structures their current names. They considered it the "Place of the Gods" - a place where, they believed, the current world was created. Mysterious Layout of Teotihuacán The city of Teotihuacán is meticulously laid out on a grid which is offset 15º.5 from the cardinal points. Its main avenue, the "Street of the Dead," runs from 15º.5 east of north to 15º.5 west of south, while its most impressive structure, the Pyramid of the Sun, is directly oriented to a point 15º.5 north of west -- the position at which the sun sets on August 13. There is one very peculiar thing about the city of Teotihuacan; It is oriented 15.5 degrees east of True North!* Teotihuacan satellite photo courtesy of © Space Imaging LLC Click on the image above to enlarge (1.9MB JPG) Do not miss this incredible website http://www.spaceimaging.com/newsroom/2005_ancientObservatories.htm The siting of the Pyramid of the Moon at the far end of the avenue was likewise done with such care that a sight-line directly over the top of the Pyramid of the Sun marks the meridian, thus allowing the priests of the city to fix the times of noon and midnight with complete accuracy. Several attempts had been made to explain the layout of Teotihuacán by means of astronomy. The most credible solution to the mystery of the orientation of Teotihuacán (and other Mesoamerican cities and archaeological sites) is provided by Dr. Vincent H. Malmström in his 1997 volume, "Cycles of the Sun, Mysteries of the Moon: The Calendar in Mesoamerican Civilization" published by the University of Texas Press. Here (with his permission) is a link to Chapter 5 of his book where he presents the main gist of his argument. History of Teotihuacan ============================== *100 BC - 0 AD Proto-Teotihuacan (two small hamlets in northern pocketof Valleyof Mexico, population = 5000) *0 BC - 150 AD Teotihuacan I - (Avenue of the Dead, Pyramid of the Sun established) *150 AD - 300 AD Teotihuacan II - (Grid pattern established) *300 AD - 650 AD Teotihuacan III - (Pinacle of development, population = 85,000 - 200,000) *650 AD - 750 AD Teotihuacan IV - Decline and fall Besides the major ceremonial pyramids, there were also palaces and temples, especially near the north end of the city surrounding the plaza in front of the Pyramid of the Moon. These included the Palace of Quetzalcoatl, the Butterfly Palace, the Temple of the Feathered Conches, and the Palace of the Jaguars. The sophistication and artistry of the Teotihuacanos can be seen everywhere in the magnificent murals and stone carvings which adorn the walls of the palaces and apartment compounds. The city met its end around 700 AD through deliberate destruction and burning by the hand of unknown invaders. Although a century earlier, around AD 600, almost all of Teotihuacan's influence over the rest of Mesoamerica had ceased, indicating some sort of internal malaise or decline before the destruction. The first strains appeared about AD 650. A century later, Teotihuacan was a shadow of its former self. The population had declined so rapidly that the once-proud city was now little more than a series of hamlets extending over an area of about a square kilometer. Some great catastrophe apparently struck the city in AD 700, reducing its population to below 70,000. Many of its people moved eastward. The city was deliberately burnt and destroyed. Over the years, its buildings collapsed and the pyramids became overgrown with dense vegetation. Teotihuacan's decline was almost as rapid as its rise to prominence. Even so, eight centuries later, Teotihuacan was still revered far and wide as an intensely sacred place. But no one remembered who had built it or that tens of thousands of people had once lived there. Away from the Avenue of the Dead, the city continued to live on for another two centuries, although the population of Teotihuacan sunk to only a quarter of its former total. Some sort of crisis overtook all the Classic civilizations of Mesoamerica (including the Maya) two centuries later, forcing them to abandon most of the cities. Some anthropologists believe the crisis may have been a lessening of the food supply caused by a drying out of the land and a loss of water sources to the area. They speculate that this might have been brought about by a combination of natural climactic shift towards aridness that appears to have happened all over Mexico during the Classic period and the residents having cut all the timber in the valley. Originally there were cedar, cypress, pine, and oak forests; today there are cactus, yucca, agave, and California pepper trees. This change in vegetation indicates a big climate shift. Although Teotihuacan presents a puzzle to archaeologists because it was a huge city that appears to have arisen without antecedents, the single most important fact which archaeologists have learned about the Classic period in Mexico was the supremacy of Teotihuacan. As the urbanized center of Mexico, with high population and tremendous production, its power was imposed through political and cultural means not only in its native highland habitat, but also along the tropical coasts, reaching even into the Maya area. It's trading and tribute empire was comparable with the Aztec empire that eventually followed it. All other Mexican states were partly or entirely dependent upon it for whatever achievements they attained. When Teotihuacan fell, around 650 AD, the unifying force in Mesoamerica was gone, and with it widespread inter-regional trade. The Late Classic period saw increasing fractionalization among cultures. In the place of great states, petty kingdoms and militarism arose. From the highpoint of civilization at Teotihuacan, wars became the rule of the day, and for those unfortunate enough to be captured, sacrifice to the gods. Military empires, such as the Toltecs in the twelfth century AD (and later the Aztecs, starting in fourteenth century AD), which grew up from these warring factions were the cultures met by the Spanish in 1519 and largely eradicated by 1521. Probably the reason that the Spanish were able to conquer the Aztecs in such a short amount of time had less to do with their skill as soldiers and more to do with the fact that the Spaniards physically resembled the descriptions in Aztec legends of the god Quetzalcoatl. Quetzalcoatl, while symbolized as a feathered serpent, appears also to have been an historic figure - the man credited with bringing civilization, learning, culture, the calendar, mathematics, metallurgy, astronomy, masonry, architecture, productive agriculture, knowledge of the healing properties of plants, law, crafts, the arts, and peace to the native people. He is pictured as a quite different physical type than the natives - fair skinned and ruddy complexioned, long nosed, and with a long beard. He was said to have arrived by boat from the east, and sailed off again years later promising to return someday. The Pyramid of the Sun ======================= The Pyramid of the Sun, built in the 2nd century AD, dominates the landscape of the ancient city of Teotihuacan in Mexico.It is the third largest pyramid in the world and the largest in the Teotihuacan complex. Image Source: Mexico and Its Ancient Ruins - PHOTO CD This sacred, truncated edifice stood 210 feet high and 650 feet square, a vast pyramid of rubble, adobe mud, and earth all faced with stone. A wooden temple on the summit of the pyramid afforded a spectacular view of the sprawling city below. The pyramid is actually a succession of pyramids built one on top the other over the centuries. The pyramids and many other structures at Teotihuacan are stepped, rather than smooth sided like the Egyptian pyramids, and the stones of which they are made are not as large as stones used to build Egyptian pyramids. At its peak time - most of Teotihuacan was plastered, and the pyramids were painted bright red. Another fascinating feature of some of the pyramidal structures is that they contain a broad, thick layer of mica, which had to be brought from Brazil, over 2000 miles away! Mica is very flaky and fragile, yet it was brought in very large pieces from great distances (and without wheeled vehicles). Then the mica was used on an inner layer of the pyramid, not where it could be seen. Why? One characteristic of mica is that it is used as an insulator in electronic and electrical things. Was that its purpose here? Another mystery of Teotihuacan. In 1971, a large cave underneath the Pyramid of the Sun was discovered which throws light on why the pyramid was constructed, and perhaps even on why Teotihuacan itself was built where it was. The cave is actually a natural lava tube enlarged and elaborated in ancient times. The Teotihuacan Valley is a side valley of the Valley of Mexico and is one of a number of natural basins in the midst of an extensive region of volcanoes, therefore, there are many caves formed from the tubes of old lava flows. The ancient use of the cave predates the pyramid. Aztec tradition placed the creation the Sun and Moon, and even the present universe, at Teotihuacan. In Pre-Spanish Mexico, such caverns were symbolic wombs from which gods like the Sun and the Moon, and the ancestors of mankind, emerged in the mythological past. This is an immensely holy spot and the memory of its location persisted into Aztec times. --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- The Pyramid of the Moon =========================== The Moon Pyramid is located at the northern end of the Avenue of the Dead, which is the main axis of the city. The pyramid, facing south, was built as the principal monument of the Moon Pyramid complex. The five-tiered platform was attached to the front of the Moon Pyramid. It is said that the present pyramid has interior structures within it. However, the pyramid still remains as one of the least understood major monuments in Teotihuacan. The current excavation under the Pyramid of the Moon may be one of the best opportunities to answer questions about the civilization, as its underlying older, primitive loose rock construction may have protected buried secrets by making it difficult to dig under and resistant to looters. ========================================================================================================================================================================== Comparing the Pyramid of the Sun with the Great Pyramid in Egypt ===================================================================== Many scholars outside the established academic circles, have produced extensive evidence that the precise arrangement, proportion and alignment of many ancient monuments expresses, at the very least, advanced and detailed astronomical knowledge well beyond that with which their builders have been credited. The Pyramid of the Sun and the Great Pyramid of Egypt are almost or very nearly equal to one another in base perimeter. The Pyramid of the Sun is "almost" half the height of the Great Pyramid. There is a slight difference. The Great Pyramid is 1.03 - times larger than the base of the Pyramid of the Sun. Conversely, the base of the Pyramid of the Sun is 97% of the Great Pyramid's base. The ratio of the base perimeter to the height: Great Pyramid Pyramid of the Sun 6.2800001... : 1 (deviates by 0.05 % from the 6.2831853 value for 2 x pi) 12.560171... : 1 (deviates by 0.05 % from the 12.566371 value for 4 x pi) The ratio of their height to the perimeter of their base are both based on the mathematical ratio 'pi'. The perimeter of the base of the Pyramid of the Sun is 4pi times its height, whereas the Great pyramid of Giza's base perimeter is 2pi times its height. The mathematical ratio 'pi' is based on knowledge of geometry, so the use of 'pi' implies knowledge of sophisticated mathematics also ================================================================================================================================by sree===================================
