Artemis is the Greek goddess of hunting, the wilderness, wild animals, transitions, nature, vegetation, childbirth, care of children, and chastity. She was often said to roam the forests and mountains, attended by an entourage of nymphs alongside mortal some mortal women. Her Roman equivalent is Diana. Artemis was the daughter of Leto and Zeus, and twin sister of Apollo. In most accounts, the twins were produced by an extramarital liaison, for which Zeus's wife Hera forbade Leto from giving birth anywhere on solid land. Only the island of Delos allowed her to give birth to her children. In one account, Artemis is born first and then proceeds to assist Leto in the birth of the second twin, Apollo. Artemis was a kourotrophic (child-nurturing) deity, being the protector of children, especially girls, and animal cubs. She was worshipped and feared as one of the primary goddesses of childbirth and midwifery along with Eileithyia and Hera. She was also a patron of healing and disease, and was believed to send good health, illness and death upon women and children, and a guardian over transitions from maidenhood. Artemis was one of the three major virgin goddesses, alongside Athena and Hestia. She was thought of as an unmarried maiden and one of the three Greek goddesses over whom Aphrodite had no power.
