Perhaps the earliest origin is the ancient city of Babylon, a major metropolis in Mesopotamia (modern Al Hillah in Iraq). Babylon is the Greek variant of Akkadian Babilu (bab-ilu), meaning "Gateway of the god". It was the "holy city" of Babylonia from around 2300 BC, and the seat of the Neo-Babylonian empire from 612 BC.
One of the goddesses associated with Babylonia was Ishtar, the most popular female deity of the Assyro-Babylonian pantheon and patron of the famous Ishtar Gate. She is the Akkadian counterpart to the Sumerian Inanna and the cognate to the northwest Semitic goddess Astarte. The Greeks associated her with Aphrodite (Latin Venus), and sometimes Hera. Ishtar was worshipped as a Great Goddess of fertility and sexuality, but also of war and death, and the guardian of prostitutes. She was Also Called the Great Whore and sacred prostitution formed part of her cult or those of cognate goddesses. Many have associated Ishtar with the figure in the Book of Revelation of Babylon the Great, Mother of Harlots and Abominations.
