We learn from history, that Janus was represented with two faces, because he governed two different people, and because he divided his kingdom with Saturn. […] Biformis, because he was accounted both bearded and beardless; or, because wine renders some cheerful and gay, and others morose and dull. […] Nictilius, because his feasts were celebrated in the night by torch light. […] A crown of olive was entwined around her helmet, because she taught the use of that fruit. […] Camillus, from his office of minister to the Gods; and Vialis, because he presided over the formation of roads.
