Hunab Ku is named in colonial Yucatec manuscripts, above all the Books of Chilam Balam and the Motul dictionary, as the sole, invisible, and incorporeal god, without form or image, from whom the other deities proceed. He is identified as the father of Itzamná, the creator who ordered the world. Sources differ on whether Hunab Ku represents a genuine Postclassic Maya conception of a single high god or a colonial abstraction produced under the pressure of Christian missionizing, since the figure is absent from the hieroglyphic codices and appears only in alphabetic texts written after the Conquest.
