Aries is the first sign of the zodiac, which is entered by the sun on or about March 21st.Aries is the first astrological sign in the Zodiac, named for the constellation of Aries, called "The Ram" in the Greek tradition, after golden ram that rescued Phrixos, taking him to the land of Colchis.
Mythology of Aries, the Ram comes from the ancient Greece, which states that the animal representing the first constellation of the zodiac was having the Golden Fleece that was always anxiously sought by Jason and the Argonauts. Mercury had presented the ram to Nephele when her husband, the king Athamus of Boetia married Ino as his second wife. Ram carried Phrixis and Helle across the sea away from their evil step-mother (step-father's don't seem to get a bad rap anywhere).
Whilst Helle fell off half way across, Phrixis made it and showed his 'thanks' by killing and skinning the ram. He hung its skin in the Grove of Ares where the fleece turned gold. It was this Golden Fleece which inspired Jason and the Argonauts. Zeus placed the Ram in the sky after it was found by Jason and dedicated to him.
In mythology, the Golden Fleece has been ascribed to enlightenment and knowledge - it embodies the spirit and the intellect. Thus, Aries is propelled to be forever on a quest. There are other myths which say Ares rode a chariot pulled by two horses, one black, and one white. They were called Deimos (Fear) and Phobos (Terror). In other myths they are known as his sons. Whether they were his horses or sons, they accompanied him into battle. He lived for the thrill of battle and the smell of blood.
