Tells of mythology of Aries can be traced to bygone ages. The Egyptians associated Aries with Amon-Re, the ram-headed supreme Sun God who symbolized power and fertility.
The Mesopotamians' name for the constellation meant a military leader or prince.
You should note during those years, it is not surprising to find a ram (symbol of Aries) in the sky, for rams were frequently sacrificed to the gods.
Zeus (ruler of Greek gods) was at times identified with a ram. But various myths agree that Aries is a special ram.
One part of Greek Mythology of Aires lays in the story of the King of Thessaly and his children, daughter Helle and son Phrixus. Because their nasty step-mother was beating them on a regular basis, Hermes the Greek god sent a ram to carry them away. On the trip, poor Helle lost her grip and fell to the sea. Where she landed was named Hellespont and now it's known as the Dardanelles today.
Her brother made it to the shore of the Black Sea and had to kill the ram for its fleece to appease a sleepless dragon. Jason and the Argonauts later came back for it and returned it the the King. Phrixos sacrificed the ram to the gods and hung its skin in a temple, where it was known as the Golden Fleece. The Golden Fleece was also the object of the voyage of Jason and the Argonauts.
Another version of Greek mythology of Aries explains that the ram made its appearance on Earth just as King Athamas of Boeotia was about to sacrifice his son Phrixos to ward off an impending famine. As the tale goes, Aries represents the golden ram that rescued Phrixos, taking him to the land of Colchis.
Mars, Roman God of War for whom the month of March is named, was the son of Juno and (dependent upon the source) either her husband, Jove, or a magical flower. He was originally the God of fertility and vegetation, but later became associated with battle. As the God of Spring, when his major festivals were celebrated, he presided over agriculture in general.
In his warlike aspect, Mars was offered sacrifices prior to combat and was said to appear on the battlefield accompanied by Bellona, a warrior goddess who drove his chariot and variously identified as his wife, sister or daughter.
Mars (unlike his Greek counterpart Ares) was more widely worshipped than any of the other Roman Gods, probably because his two sons, Romulus and Remus, were believed to have founded the city...Romulus later slaying Remus during a quarrel over the proposed site.
Despite his reputation and typical depiction as a warrior in full battle regalia complete with crested helmet, shield and lance, Mars was not known to be a brilliant soldier. He first began the practice of war by becoming involved in the squabbles which constantly took place in Olympus but soon began to enjoy fighting for its own sake. He often blundered into battle and was easily tricked.
For example, it is written that the Goddess Athene defeated him twice...Hercules forced him to retreat from Earth to Olympus...and the Giants imprisoned him for thirteen months in a bronze vessel. He was said to have raped the vestal virgin, Rhea Silvia (mother of Romulus and Remus) and, when he reclined upon the couch of Venus in the arms of this Goddess, her husband (Vulcan) trapped them there with an invisible net. They were forced to lie, locked in an embrace, while the other Immortals guffawed at their predicament.
On another occasion, the Gods tried Mars for murdering the son of Neptune, but he was released based on the plea that he was saving his daughter from being ravished. This statement is subject to doubt since Mars was known to be an ingenious liar. Eventually, Mars came to be considered as the God of Purposeless War. The Greeks (who knew him as Ares) rather despised this God, but the Romans made him a hero and he always supported their legions.
