Diana is a goddess in Roman and Hellenistic religion, primarily considered a patroness of the countryside, hunters, crossroads, and the Moon. She is equated with the Greek goddess Artemis, and absorbed much of Artemis' mythology early in Roman history, including a birth on the island of Delos to parents Jupiter and Latona, and a twin brother, Apollo, though she had an independent origin in Italy.
Diana is considered a virgin goddess and protector of childbirth. Historically, Diana made up a triad with two other Roman deities: Egeria the water nymph, her servant and assistant midwife; and Virbius, the woodland god.
Diana is revered in modern neopagan religions including Roman neopaganism, Stregheria, and Wicca. From the medieval to the modern period, as folklore attached to her developed and was eventually adapted into neopagan religions, the mythology surrounding Diana grew to include a consort (Lucifer) and daughter (Aradia), figures sometimes recognized by modern traditions. In the ancient, medieval, and modern periods, Diana has been considered a triple deity, merged with a goddess of the moon (Luna/Selene) and the underworld (usually Hecate).
