Ishtar later became Aphrodite of the Greeks and Venus of the Romans. She was also a major deity for the Assyrians and Babylonians, and presumably for the Chaldeans. She was the Astarte of the Sumerians. The words Esther and Easter derive from her name and worship. The word star also derives from Ishtar. Similar to the Egyptian Isis and Nuith, Ishtar was a goddess of the heavens. She was a prototype for the Christian Mary.
