The correct spelling of this name is ENHEDUANNA.
Enheduanna was a high priestess in Ur, an ancient Sumerian city. The oldest known author in the world, she wrote in cuneiform and left three known works: two hymns to the goddess Inanna and a third concerned with the sacred temples, their priests, and their gods. Enheduanna described herself as a daughter of Sargon, a Mesopotamian ruler, but the statement may or may not be literal.
