"As Assyrian astrological text, which deals with the effects of the stars on potency and lovemaking, includes verses indicating the region of Libra is auspicious for the love of a man for a woman, and Scorpio, for the love of a man for a man. An Almanac of Incantations from the Babylonian period contains prayers to be said by a man seeking the love of a woman, a woman for a man, and also prayers for a man to seek another man. Other religious tablets have been found which contain text referring to homosexual relations, such as “if a man has intercourse with his male companion.” Lesbian relations between women were also mentioned in similar texts, often enough to assume they were commonplace."
