Ninsun means Lady Wild Cow, which implies bovine form. But the Sumerian deity was actually called many things: "the flawless cow," "the wild cow of the enclosure" and "the mother of good offspring that loves the offspring." It's said that she was the divine power behind the qualities that herdsmen hoped for in their own cows. But she wasn't just in cow-like form. She was also represented in human form and could actually give birth to humans, including (legend has it) to Gilgamesh, one of the great mythical Mesopotamian kings.
