Related to some information contained in the post below, about the traditional (i.e., pre-Islamic) Persian celebration of the New Year. From Barbara Walker's "The Woman's Encyclopedia of Myths and Secrets:"
This and its variations Anahita and Anitis were the Persian and Armenian names for Venus, the star of Ishtar and Astarte, Mother Goddess of the Zend-Avesta; ruler of waters, stars, and Fate. The Mithraic Mysteries, though strongly male-oriented, retained Anahita as the necessary female principle of creation.(1)
