(Latin: Ram) In astronomy, the constellation lying between Pisces and Taurus; in astrology, the first sign of the zodiac, governing approximately the period March 21–April 19. It is represented by a ram, which is sometimes identified with the Egyptian god Amon. In Greek mythology Aries was identified with the ram that carried the prince Phrixus out of Thessaly to Colchis. Phrixus sacrificed the ram to Zeus, who placed it in the heavens as a constellation. Its golden fleece was later recovered by Jason.
