Two of the most important younger Olympians are Artemis and Apollo, twin children of Zeus and the goddess Leto. Apollo is associated with reason, moderation, prophecy, healing and medicine, but also with sudden death. His most important role is as the god of prophecy at the Oracle of Delphi. Artemis is associated with wildness as the huntress and protector of wild animals and women. She brings sudden death to women. The story of Actaeon illustrates that even unintentional violations of boundaries between gods and humans can lead to disaster in Greek mythology.
