 Diana is the Roman Goddess of the hunt and the moon, the equivalent of Artemis in Greek mythology. One of three goddesses sworn to chastity, Diana was also the protector of virgins, and of women more generally. She is often depicted as a young woman carrying a bow and arrow, and accompanied by a deer or a hunting dog; she was strongly associated with woodland and wild animals.
