Daughter of Zeus and Leto, Artemis is the virgin goddess of the hunt, child birth and fertility, also a member of the Twelve Olympians, together with her twin brother, Apollo, the god of arts. Depicted as a beautiful young woman, she is always said to carry her silver bow and arrows, and one of her main tasks was to protect the forests and hills. The deer and the cypress were sacred to her. As one of the most venerated deity in the Ancient Greece, her figures appears constantly in various myths, usually as the one who executes punishments upon mortals who broke their oaths or has offended the gods. All of her female followers are said to take a vow of maidenhood. Callisto was one of Artemis' loyal companions, but Zeus raped her and as a result, she is transformed into a bear by Artemis. Orion, another loyal companion who was also a valiant hero, was killed by a scorpion. Artemis then asked her father to resurrect him, and Zeus placed him among the stars. Later in history, she started to be associated with the Moon, overshadowing Selene, the personification of the Moon itself. She is known as Diana in the ancient Rome.

Artemis was worshiped as a many-breasted earth mother in Ephesus.
