 As the precise studies of Johanna Broda have shown, the creation myth consisted of “several layers of symbolism, ranging from a purely historical explanation to one in terms of cosmovision and possible astronomical content.” At one level, Huitzilopochtli's birth and victorious battle against the four hundred children represent the character of the solar region of the Aztecs in that the daily sunrise was viewed as a celestial battle against the moon (Coyolxauhqui) and the stars (Centzon Huitznahua).Another version of the myth, found in the historical chronicles of Diego Duran and Alvarado Tezozomoc, tells the story with strong historical allusion and portrays two Aztec factions in ferocious battle.The leader of one group, Huitzilopochtli, defeats the warriors of a woman leader, Coyolxauh, and tears open their breasts and eats their hearts.
