Mankind in the earliest age lived for a time without a single vicious impulse, without shame or guilt, and, consequently, without punishment and restraints. Rewards were not needed when everything right was pursued on its own merits; and as men desired nothing against morality, they were debarred from nothing by fear. When however they began to throw off equality, and ambition and violence usurped the place of self-control and modesty, despotisms grew up and became perpetual among many nations. Some from the beginning, or when tired of kings, preferred codes of laws. These were at first simple, while men's minds were unsophisticated. The most famous of them were those of the Cretans, framed by Minos; those of the Spartans, by Lycurgus, and, subsequently, those which Solan drew up for the Athenians on a more elaborate and extensive scale. Romulus governed us as he pleased; then Numa united our people by religious ties and a constitution of divine origin, to which some additions were made by Tullus and Ancus. But Servius Tullius was our chief legislator, to whose laws even kings were to be subject.
