Iah is a god of the moon in ancient Egyptian religion, and his name, jˁḥ (sometimes transliterated as Yah, Jah, or Aah), simply means "moon". Nevertheless, by the New Kingdom he was less prominent as a moon deity than the other gods with lunar connections, Thoth and Khonsu. As a result of the functional connection between them he could be identified with both of those deities. He was sometimes considered an adult form of Khonsu, and was increasingly absorbed by him. Iah continued to appear in amulets and occasional other representations, similar to Khonsu in appearance, with the same lunar symbols on his head and occasionally the same tight garments. He differed in wearing a full wig instead of a child's sidelock, and sometimes an atef crown topped by another moon symbol.
