A goddess who can hardly be distinguished from Bau is Ga-tum-dug. Indeed, from the fact that she is also the 'mother of Lagash, it might seem that this is but another name for Bau. For Gudea, Ga-tum-dug is the mother who produced him. He is her servant and she is his mistress. Lagash is her beloved city, and there he prepares for her a dwelling-place, which later rulers, like Entena, embellish.
