Mythical Origins
According to an Aztec myth, the pyramid of Cholula was built by the giant Xelhua, after having escaped a flood, in one of the ancient eras preceding the Aztec world. This mythical builder also shares his name with a cultural hero of the Tolteca-Chichimeca. In the Historia Tolteca-Chichimeca--an ethnohistoric document written in the 16th century--Xelhua guided his people to Tollan-Cholollan (Cholollan means "Place of the flight") in the 12th century. The area was already occupied by the Olmeca-Xicallanca who, according to the same source, constructed the pyramid and carried out sacrifices on top of the "Chalchiutépec" (Nahuatl word that means "mountain of jade")--a metaphor to indicate the sacredness of the great pyramid.
