In Syria, Astarte was the Great Mother goddess and queen of prostitutes. Her worship culminated at the vernal equinox. This is about March 21 of each year, when the day and night are of equal length; we today call it the first day of spring. The well-known historian, Will Durant, explains how her lover was celebrated with sexual orgies, by the pagans, on March 21:
“Religious prostitution flourished, for in Syria, as throughout western Asia, the fertility of the soil was symbolized in a Great Mother, or goddess, whose sexual commerce with her lover gave the hint to all the reproductive processes and energies of nature; and the sacrifice of virginity at the temples was not only an offering to Astarte, but a participation with her in that annual self-abandonment which, it was hoped, would offer an irresistible suggestion to the earth, and insure the increase of plants, animals, and men.
“About the time of the vernal equinox, the festival of the Syrian Astarte, like that of Cybele in Phrygia, was celebrated at Hierapolis with a fervor bordering upon madness. The noise of flutes and drums mingled with the wailing of the women for Astarte’s dead lord, Adoni; eunuch priests danced wildly, and slashed themselves with knives . . Then in the dark of the night, the priests brought a mystic illumination to the scene, opened the tomb of the young god, and announced triumphantly that Adoni, the lord, had risen from the dead. Touching the lips of the worshipers with balm, the priests whispered to them the promise that they, too, would some day rise from the grave.”— Will Durant, History of Civilization, Vol. 1, 296-297.
