Apollo "working from afar". While Apollo presided over the prophetic powers and magic of light and heaven, Hecate presided over the prophetic powers and magic of night and chthonian darkness. If Hecate is the "gate-keeper", Apollo "Agyieus" is the "door-keeper". Hecate is the goddess of crossroads and Apollo is the god and protector of streets. The oldest evidence found for Hecate's worship is at Apollo's temple in Miletos. There, Hecate was taken to be Apollo's sister counterpart in the absence of Artemis. Hecate's lunar nature makes her the goddess of the waning moon and contrats and complements, at the same time,
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.
