In Aztec mythology, the god Nanahuatzin the most humble of the gods, sacrificed himself in fire so that he would continue to shine on Earth as the Sun, thus becoming the sun god. Nanahuatzin means "full of sores." According to a translation of the Histoyre du Mechique, Nanahuatzin is the son of Itzpapalotl and Cuzcamiahu or Tonan, but was adopted by Piltzintecuhtli.
