Penthesilea was a Queen of the Amazons and one of the daughters of Otrera and Ares. She was the sister of Hippolyta, Antiope and Melanippe. She was killed by Achilles in the Trojan War. She like her sisters was also a legacy of Eurus.
Penthesilea was the third daughter of Otrera and Ares, the god of war. She became queen of the Amazons after the death of Orithyia, her half-sister who died in the Attic War.
Penthesilea arrived in Troy the night before the fighting is due to recommence following Hector's death and funeral. She came to Troy to prove to others that her people, the Amazons, are great warriors and can share the hardships of war. She arrived with twelve companions and promised the Trojans that she would kill Achilles. On her first and only day of fighting, Penthesilea kills many Greeks and clashes with Telamonian Ajax, although there is no clear victor, before she comes face to face with Achilles, who had been summoned by Ajax. Prior to Achilles' entrance, Penthesilea had tried to fight Ajax but he had merely laughed off her attempts, thinking her an unfit opponent. With only one blow to her breastplate, Achilles knocks her to the ground and she begs for her life. He is unmoved, kills her, and mocks her corpse until he removes her helmet and feels strong remorse.
