Artemis

Greek goddess of the moon, wild animals, hunting, childbirth, etc. (identified by the Romans with their Diana); daughter of Zeus and Leto, twin sister of Apollo; her name is of unknown origin. Beekes points to arguments against the attempt to connect it with arktos "bear" (as "bear-goddess") and finds it possibly Pre-Greek.

The name is found in Lydian inscriptions (Artimus, Artimu-), and Lycian has ertemi, but this does not prove that the name comes from Lydia or Asia Minor. [Beekes]
