"The twin-pyramid groups seem well suited as stages. Their ceremonies could be big, sumptuous, and involve a large percentage of the total community...I believe there is some reason to suggest that the twin-pyramid groups were built, not only to mark a katun [twenty year ritual period], but to serve as a stage for ceremonies directed toward the god of the katun. There are several approaches to this argument. The groups are suited for public ceremony; the succession of the groups reflects the succession of the katuns; and finally, there are some parallels between the form of the groups and the form of katun-worship in the 16th century Yucatan."
