Xelhua
Xelhua is one of the seven giants in Aztec mythology who escaped the flood by ascending the mountain of Tlaloc in the terrestrial paradise, and afterwards built the Great Pyramid of Cholula. A Dominican monk wrote this account:
Xelhua was a giant of the "time of the universal deluge." He was one of the seven giants in the Aztec culture. Before the pyramid in Mesoamerica was complete, "fire fell upon it, causing the death of its builders and the abandonment of the work."
