Some Obscurish facts

Teotihuacán – Teotihuacán, in Mexico, is an immense, even overwhelming archaeological site, oriented along a twin axis. In the 1960s a team of archaeologists and surveyors mapped out the entire complex in great detail. The resultant map revealed an urban grid centred around two principal, almost perpendicular, alignments. From the Pyramid of the Moon at the north end, the complex extends south along the Avenue of the Dead beyond the Ciudadela and Great Compound complexes for about 3.2 kilometres. To this north-south axis we must add an east-west alignment that led from a point near the Pyramid of the Sun to a spot of prime astronomical significance on the western horizon. Anthony Aveni, an astronomer-anthropologist, discovered that on the day the Sun passes directly overhead in the spring of the Northern Hemisphere (May 18), the Pleiades star cluster makes its first annual predawn appearance. It was at this point on the western horizon that the Pleiades set, and the builders aimed the east-west axis. Additionally, the Sun also sets at this point on the horizon on August 12 – the anniversary of the beginning of the current Mesoamerican calendar cycle (5th Sun) – determined by a consensus of academic and independent scholars to have begun on August 12, 3114 BCE. It is very clear Teotihuacán was laid out according to a set of alignments that reflected celestial, geographic, as well as geodetic relationships. Walking along the avenue from one pyramid to another, up the steps to the top, and surveying the site from a multitude of angles, one is struck by the sense of being in the middle of some vast geometric matrix. Teotihuacán was the first true urban centre in the Americas. At its peak around 500 CE, it boasted a population of an estimated 200,000. George E. Stuart, archaeologist and the editor of National Geographic magazine sums up our ignorance: We speak of it with awe, as we do the pyramids of Egypt, but we still know next to nothing about the origins of the Teotihuacános, what language they spoke, how their society was organised, and what caused their decline.2 As for one the most anomalous of artefacts on the planet, in the 1900s archaeologists discovered a sheet of mica in the upper tiers of the Pyramid of the Sun. This was no ho-hum pottery shard to catalogue and file away in a dusty box, yet that is about how archaeologists treated the find. To anyone with even a smattering of technical knowledge, discovering a large sheet of mica in an ancient pyramid site comes as a shock. In fact, it is one of the great ‘smoking guns’ that turn archaeologists mum. Mica is an inflammable and non-conductive mineral that grows in fairly weak plate-like structures. It is not at all useful as a structural building material. NASA uses it as a radiation shield in space vehicles. Mica is also utilised in electronic components and microwave ovens, and it is a good shield for electromagnetic radiation, like radio waves. Like the Great Pyramid, the Pyramid of the Sun has a subterranean cavity under the middle of the pyramid. A large pyramid with layers of thick mica would be an excellent EMI shield. Its placement in the complex raises questions that we could only answer today after the development of electronic, atomic and space age technologies. Thick sheets of mica were also found by archaeologists about 400 meters down the avenue from the Sun Pyramid, these precision-cut sheets were of considerable size: 27.5 meters square. They were located under a rock-slab floor of a complex now called the Mica Temple. What possible reason could the builders have had for including a layer of mica in any structure? It was obviously not decorative. To add greatly to the growing mystery, the particular mica used was traced to Brazil. Now we are getting in deep. How would a supposedly indigenous “Stone Age” culture know that mica existed 3200 kilometres away in the jungles of Brazil? Not only that, how did they transport these large sheets over that long distance intact without wheeled vehicles? Surely not via relay teams on foot travelling overland! No large seagoing boats or ports have ever been found in ancient Mexico.
