Bel-Shalti-Nanna

Ennigaldi-Nanna, also known as Bel-Shalti-Nanna and commonly called just Ennigaldi, was a princess of the Neo-Babylonian Empire and high priestess (entu) of Ur. As the first entu in six centuries, serving as the "human wife" of the moon-god Sin, Ennigaldi held large religious and political power. She is most famous today for founding a museum in Ur c. 530 BC. Ennigaldi's museum showcased cataloged and labelled artifacts from the preceding 1,500 years of Mesopotamian history and is often considered to have been the first museum in world history.
