Suicide of Ajax: When Achilles was killed, his armor was to be awarded to the next greatest Greek hero. Ajax thought it should go to him. Ajax went mad and tried to kill his comrades when the armor was awarded to Odysseus, instead. Athena intervened by making Ajax think cattle were his former allies. When Ajax realized he had slaughtered the herd, he committed suicide as his only honorable end. Ajax used the sword Hector had given him to kill himself.
