The Venus Tablet of Ammi-Saduqa. Nineveh, Mesopotamia: A Sumerian scribe records the movements of the stars, including Venus, on a clay tablet. It depicts the conjunction between Venus and the Sun during the reign of Ammi-Saduqa. This document is important because it demonstrates that the Sumerians had already understood that the Morning Star and the Evening Star were the same celestial body. Centuries later, in ancient Greece, the two stars were referred to by different names: Phosphorus (bringer of light, Lucifer in Latin) and Vesper.
