To Gilgamesh, Eabani's coming is revealed and he asks his mother Aruru to interpret the dream.
Aruru being a goddess, it was not so easy to have Marduk take up her rôle, as he supplanted Bel.
Aruru washed her hands, she broke off a piece of clay, she cast it on the ground.
I venture to suggest, therefore, that Aruru and Ishtar of Erech are one and the same personage.
Have we perhaps in Aruru the real name of the old goddess of Erech?
