Astennu

In Egyptian mythology, Astennu (also spelt Asten, Isten, Astes, and Isdes) refers to a baboon associated with Thoth. It was also stated that Astennu was merely another aspect of Thoth, as the god could take the form of a baboon. He was one of four baboons who stood around the lake of fire at the place of judgement in Duat, and consequently associated with Utennu.
