Athena is the Greek goddess of wisdom, courage, inspiration, civilization, philosophy, justice, law, mathematics, strength, arts, crafts, skill and reason. She represents just decisions and strategic warfare and is the only goddess allowed to carry Zeus’ thunderbolts. She led battles as the disciplined, strategic side of war, in contrast to her brother Ares, the patron of violence, bloodlust and slaughter. She was depicted crowned, with a crested helm, armed with a shield and spear. She is commonly shown accompanied by her sacred animal, the owl. She is the virgin patron of Athens, which was named in honour of her (the Parthenon, which overlooks the city, was a temple the Athenians dedicated to her.) The Greeks especially also associate the olive with her, as she won a contest to decide who would be the patron god or goddess of what would become Athens when she planted an olive tree as a gift to the city.
