I became a believer in the 535 A.D. catastrophe when I pulled out my Time-Life book on the Mayans (written before the David Keys book) to see what they were doing at that time. They did nothing. The book said that between 534 and 593, the city of Tikal left no written records.
Wow! If this happened today I wonder how we would react?
They were doing something, but one of those things wasn’t slaving to build some nesting-doll temple. :’)
