Sumerian/Babylonian goddess of love, lust, sex, war and violence
Ishtar is defiantly one of my absolute favorite deities. In one myth, she goes down into the underworld to see her sister, but ends up dying. To return to the world above, she had to choose a replacement. She went up and found that her husband was not morning her. Ishtar became angry and chose him as her replacement (his sister takes half of his punishment every year, hence seasons). She is comparable to Venus, and is associated with the Morning Star (Venus).
