Itzamná is the supreme creator and celestial deity of the Yucatec Maya, portrayed as an aged, toothless lord with a large aquiline nose. Diego de Landa records him as the greatest of the gods and the inventor of writing, books, and the sacred calendar, making him patron of scribes and priests; he was also invoked as a benevolent healer under names such as Itzamna Kauil and Kabul. In the Postclassic codices he corresponds to God D, an old man seated in a sky-band who presides over the other deities. His name, whose etymology remains disputed between readings such as 'iguana house' and 'house of dew or sacred fluid,' links him to the reptilian, celestial monster that forms the surface of the sky. He is paired with the goddess Ix Chel, and his solar aspect is often identified with Kinich Ahau.
