“191. It seems not inappropriate, before leaving our discussion of man’s nature, to point out what different people have discovered. Bacchus introduced buying and selling, the crown, the royal emblem and the triumphal processions. Ceres discovered corn; previously men had lived on acorns. She also invented milling and the making of flour in Attica (or, according to some authorities, in Sicily). This was the reason that Ceres was judged to be a goddess. Ceres was also the first to give laws – or, as others think, it was Rhadamanthus.”
