In Sumerian mythology, Ninsun is a goddess, best known as the mother of the legendary hero Gilgamesh.
In the Epic of Gilgamesh, Ninsun is depicted as a human queen who lives in Uruk with her son as king. Since the father of Gilgamesh was Lugalbanda, it stands to reason that Ninsun procreated with Lugalbanda to give birth.
Ninsun is called "Rimat-Ninsun", the "august cow", the "Wild Cow of the Enclosure", and "The Great Queen".
