Minerva's own origins lie outside Rome altogether. She descends from the Etruscan goddess Menrva, herself likely shaped by early contact with Greek Athena, and reached Rome through the same channel of Etruscan influence that gave the city its early kings. The archaic Capitoline Triad of Jupiter, Juno and Minerva, worshipped together in one temple on the Capitoline Hill, is widely thought by scholars of Roman religion to reflect this Etruscan inheritance rather than any native Latin arrangement, since a comparable grouping of three principal deities sharing one large temple is a recognisable pattern at other Etruscan sanctuaries, and the Tarquin kings under whom the Capitoline temple was built and planned were themselves of Etruscan background.
Only later did Minerva's Etruscan and Italic character fold almost completely into that of Athena, so that by the historical period Romans described her almost entirely in Greek terms, wisdom, strategic warfare, weaving and craft, while the Etruscan Menrva behind her name survived mainly in inscriptions and mirror-back engravings rather than in Roman literature, which had already forgotten, or chose not to record, how much of the goddess it inherited from a non-Latin source.
