In Greek mythology, Artemis was the twin sister of Apollo and goddess of the hunt and the wilderness. She was also known as a goddess of healing, fertility, and childbirth.
Artemis doesn’t have many enemies that earned her wrath, but when they did, they or someone they loved, ended up dead. Her enemies were mostly lecherous men and gods, braggarts that boasted of their superior hunting prowess, such as the Aloadae and Agamemnon, and women that doubted her virginity or insulted her mother, such as Niobe. Others that gained Artemis’ ire were her hunting attendants or handmaidens that took vows of chastity and were either seduced or raped.
The Aloadae were the giant twin sons of Poseidon. Otos and Ephialtes were great hunters that never stopped growing. They boasted of one day getting tall enough to reach heaven, where they would kidnap Artemis and Hera and make them their wives. Artemis, knowing that nothing could kill them but each other, sent a deer to leap between them while they were hunting. The Aloadae threw their spears at the deer at the same time. Their spears missed the deer and the brothers killed each other.
Niobe, Queen of Thebes, boasted that she was superior to Leto (Artemis’ mother) because she had 14 children; seven boys and seven girls, whereas Leto only had one of each. Enraged at the insult to her mother, Artemis killed Niobe’s daughters and Apollo killed her sons.
Artemis took the side of the Trojans during the Trojan war, as she was worshipped in the city of Troy along with her brother Apollo. During which she antagonized the Mycenae king Agamemnon and his Achaean troops on their way to the Troy, where they would attempt to take Helen back for the king’s brother, Menelaus— of whom Helen was originally married to before Aphrodite made her fall in love with Paris.
Agamemnon killed Artemis’ sacred stag in a holy grove and bragged that he was a better hunter than she, so she punished him on his journey to Troy by stopping the winds. He was forced to sacrifice his beloved daughter Iphigenia to Artemis in order to bring them back.
