Xipe Totec was the "god of the sea-shore people, the proper god of the Zapotecs." When he was unhappy with his people, he caused a great array of eye irritations and diseases. To be cured, people agreed to wear the skins of flayed men during the celebration of the feast of Xipe Totec, called the "Feast of the Flaying of Men." (central Mexico, sixteenth century)

And of all those who were thus to die, it was said: “They raise poles for the striped ones.” They were brought to Yopico, [Xipe] Totec’s temple. There they made them fight in mock battle, in the same manner as they would later die, [when] they would tear their hearts out of them. They counterfeited this with them. [Using] tortillas of ground corn which had not been softened in lime [as mock-haters], they thus cut their hearts out. (16th century, Mexico City)
