 More generally, Itzamna was the creator of humankind, and also the father of Bacab (Francisco Hernández), a fourfold deity of the interior of the earth.In an alternative tradition, Itzamna begot thirteen sons with Ixchel, two of whom created the earth and humankind (Las Casas).In the New Year pages of the Dresden Codex, god D is given a role similar to that of Itzamna in Landa's description of these rituals.
