07/12/1993 - The Technology of Teotihuacan
Dr. Moira Gunn interviews Dr. George Cowgill, a Teotihuacan
anthropologist at Arizona State University and at the Center for the
Advanced Study of Behavioral Sciences at Stanford University. Dr.
Cowgill discusses Teotihuacan, the oldest city in North America.
Located near Mexico City, Teotihuacan existed from 100 A.D. to 750
A.D., maintained a population of 100,000 to 200,000 people, and at
that time ranked as the sixth largest city in the world. The city
boasts great pyramids which exist to this day, although the society
had no metal, no wheels, and no beasts of burden.
In the second half, Moira speaks with Leslie Bone, Archeological
Objects Conservator for the Fine Arts Museums of San Francisco. In
1976, DeYoung Museum received a bequest of over 70 murals from
Teotihuacan, which they have restored. Ms. Bone discusses the
technology used in making the murals and the technology of
restoration. Many of these murals have been returned to Mexico.
The exhibition "Teotihuacan: City of the Gods" will be presented in
San Francisco from May 26th through October 31st. It contains 200
objects from the national Mexican collections and from public
collections throughout the world.
