Goddess name "Anat in Mesopotamia"
In Akkadian the form one would expect Anat to take would be Antu earlier Antum. This would also be the normal femanine form that would be taken by Anu, the Akkadian form of An 'Sky', the Sumerian god of heaven. Antu appears in Akkadian texts mostly as a rather colorless consort of Anu, the mother of Ishtar in the Gilgamesh story, but is also identified with the northwest Semitic goddess Anat of essentially the same name. It is unknown whether this is an equation of two originally separate goddesses whose names happened to fall together or whether Anat's cult spread to Mesopotamia where she came to be worshippped as Anu's spouse because the Mesopotamia form of her name suggested she was a counterpart to Anu.
