Penthesilea was a warrior queen of the Amazons, fighting on the side of the Trojans. In his battle with her, the Greek hero Achilles was so distracted by her beauty that he almost lost the contest. In the end, Achilles did kill her. In some accounts he grieved over her body; in other accounts, far more gruesome, he raped her corpse.
