Diana (mythology) of the asylum. Worship of Diana probably spread into the city of Rome beginning around 550 BCE, during her Hellenization and combination with the Greek goddess Artemis. Diana was first worshiped along with her brother and mother, Apollo and Latona, in their temple in the Campus Martius, and later in the Temple of Apollo Palatinus. The first major temple dedicated primarily to Diana in the vicinity of Rome was the Temple of Diana Aventina (Diana of the Aventine Hill). According to the Roman historian Livy, the construction of this temple began in the 6th century BCE and was inspired by
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.
