Diana (mythology) influence of Greek and Etruscan religion. By the 3rd century BCE, Diana is found listed among the twelve major gods of the Roman pantheon by the poet Ennius. Though the Capitoline Triad were the primary state gods of Rome, early Roman myth did not assign a strict hierarchy to the gods the way Greek mythology did, though the Greek hierarchy would eventually be adopted by Roman religion as well. Once Greek influence had caused Diana to be considered identical to the Greek goddess Artemis, Diana acquired Artemis' physical description, attributes, and variants of her myths as well. Like Artemis, Diana
Iana (goddess) to "Dianium", referring to either a shrine or the Temple of Diana on the Aventine Hill. Diana is one of the Roman goddesses most often identified with the moon, but Usener thought Iana might be better identified with Juno Lucina. The Church Father Tertullian, however, calls Iana a "diva arquis", "goddess of arches" (Latin "arcus" or "arquus", "arch; rainbow"). The arch as a passageway or portal suggests Iana as the female counterpart of Janus, whose role as a "doorkeeper" includes functions pertaining to time and the heavens. Varro's contemporary Nigidius Figulus identified Janus with Apollo and Iana with Diana. W.H.
