Randall Carlson explains how the onset of the Little Ice Age ended the cathedral-building era, causing Freemasonry to shift from "operative" to "speculative" to preserve scientific knowledge. He points out that the building of Gothic cathedrals coincided exactly with major architectural waves in the Mayan civilization, Indochina, and North American mound builders. Carlson highlights that these disparate cultures used the same underlying geometrical and astronomical templates.
