Ajax was the son of Telamon of Salamis. He was one of the heroes who fought for Greece in the battle of Troy.
After Achilles died, there was a contest hheld among the other heroes. The winner would recieve Achilles' armour, which had been forged by Hephaistos. Odysseus won the armour, and Ajax became envious. Ajax decided to attack his comrades in the night, but Athena tricked him and he ended up attacking and killing a flock of sheep instead. Ajax was so overwhelmed by fear of his own capacity for evil that he fell on his own sword and ended his life.
