" This magnificent structure, toward which everything in the outer chamber was directed, represents the essence of religious communication as practiced by the ancient North Americans. Although it was capable of communication with a large number of gods, the altar seems to have been intended primarily for communion with the gods MOVIEA and MOVIEB. Judging by impact marks on the top and sides of the upper altar, some aspect of this communication was dependent upon pounding the surface. Communication with the altar was symbolically continued into eternal life by placing the communicator box in the hand of the deceased. "
