In the Valley of Mexico there lived a pious man named Tapi. Creator told him to build a boat to live in, to take his wife and a pair of every animal that existed. Neighbors thought he was crazy. As soon as he finished, it began to rain. The valley flooded; men and animals went to mountains, but they were submerged. The rain ended, waters receded, etc. Tapi realized that the flood waters had receded after having sent a dove that did not return. Tapi rejoiced.
