Hu (ḥw), in ancient Egypt, was the deification of the first word, the word of creation, that Atum was said to have exclaimed upon ejaculating or, alternatively, his circumcision, in his masturbatory act of creating the Ennead. Hu is mentioned already in the Old Kingdom Pyramid texts (PT 251, PT 697) as companion of the deceased pharaoh. Together with Sia, he was depicted in the retinue of Thoth, with whom he was also occasionally identified.
