 According to a translation of the "Histoyre du Mechique", Nanahuatzin is the son of Itzpapalotl and Cuzcamiahu or Tonan, but was adopted by Piltzintecuhtli and Xōchiquetzal.In the Codex Borgia, Nanahuatzin is represented as a man emerging from a fire.This was originally interpreted as an illustration of cannibalism.
