Roman simply denotes a citizen of Rome, and the name carries that civic identity forward -- less a description of personal traits than an inherited association with order, permanence, and the kind of strength built through lasting institutions rather than individual feats.
Venus is opposite to Mercury. He comprehends languages and discipline; she delights and pleasures, Jupiter the like to Mars; this coveteth mercy and justice; that, impiety and cruelty. - William Lilly (1602.-1681.)
