We are accustomed to architects' omnipotence; their deification, however, goes back to the dawn of history. In Mesopotamia, Enki, one of the three great gods of the Sumerian pantheon, was considered an architect-god, charged with ordering the world and teaching men how to continue with this task, putting together and dwelling in the world. Through the figure and actions of Enki, especially in the field of architecture and described in various myths, this essay attempts to evaluate Mesopotamian architectural and urban imagination, perhaps not so different from our own.
