 Although one finds God D's Classic name glyph commonly rendered as "Itzamnaaj", this reading still awaits confirmation.The early colonial sources variously connect, and sometimes identify, Itzamna with Hunab Ku (an invisible high god), Kinich Ahau (the sun deity), and Yaxcocahmut (a bird of omen).The most reliable source on Itzamna, Diego de Landa, mentions him several times in the framework of his description of the ritual year.
