ABOUT TEOTIHUACAN Rising 20 stories above the central Mexican highlands, the pyramids of Teotihuacan (pronounced tay-oh-tee-wah-con) were central to Toltec learning and culture. The city, about the size of ancient Athens and Rome, was abandoned about 1500 years ago. Some believe the city was attacked by an invading army, such as the Toltecs, while newer evidence points to an internal, class-based struggle. Using an advanced understanding of mathematics, geometry and astronomy, the Toltecs built the largest pyramid, "The Pyramid of the Sun," with an alignment to coincide with the two days (May 19th and July 25th) when the sun would be directly over the top of the pyramid at noon. This would also create an alignment to the east toward the rising sun and to the west for the setting sun. This pyramid has a base only 10 feet shorter on each side than the Great Pyramid of Cheops in Egypt.
