 Some aspects of archaic Roman religion survived in the lost theological works of the 1st-century BC scholar Varro, known through other classical and Christian authors.The earliest pantheon included Janus, Vesta, and a leading so-called Archaic Triad of Jupiter, Mars, and Quirinus, whose flamens were of the highest order.According to tradition, Numa Pompilius, the Sabine second king of Rome, founded Roman religion; Numa was believed to have had as his consort and adviser a Roman goddess or nymph of fountains and of prophecy, Egeria.
