Dieuchidas says he was the sixth from Patrocles and the eleventh from Hercules. Be this as it will, Sous certainly was the most renowned of all his ancestors, under whose conduct the Spartans made slaves of the Helots, and added to their dominions, by conquest, a good part of Arcadia. There goes a story of this king Sous, that, being besieged by the Clitorians in a dry and stony place so that he could come at no water, he was at last constrained to agree with them upon these terms, that he would restore to them all his conquests, provided that himself and all his men should drink of the nearest spring. After the usual oaths and ratifications, he called his soldiers together, and offered to him that would forbear drinking his kingdom for a reward; and when not a man of them was able to forbear, in short, when they had all drunk their fill, at last comes King Sous himself to the spring, and, having sprinkled his face only, without swallowing one drop, marches off in the face of his enemies, refusing to yield up his conquests, because himself and all his men had not, according to the articles, drunk of their water.
Although he was justly had in admiration on this account, yet his family was not surnamed from him, but from his son Eurypon (of whom they were called Eurypontids); the reason of which was that Eurypon relaxed the rigour of the monarchy, seeking favour and popularity with the many. They, after this first step, grew bolder; and the succeeding kings partly incurred hatred with their people by trying to use force, or, for popularity's sake and through weakness, gave way; and anarchy and confusion long prevailed in Sparta, causing, moreover, the death of the father of Lycurgus. For as he was endeavouring to quell a riot, he was stabbed with a butcher's knife, and left the title of king to his eldest son, Polydectes.
He, too, dying soon after, the right of succession (as every one thought) rested in Lycurgus; and reign he did, until it was found that the queen, his sister-in-law, was with child; upon which he immediately declared that the kingdom belonged to her issue, provided it were male, and that he himself exercised the regal jurisdiction only as his guardian; the Spartan name for which office is prodicus. Soon after, an overture was made to him by the queen, that she would herself in some way destroy the infant, upon condition that he would marry her when he came to the crown. Abhorring the woman's wickedness, he nevertheless did not reject her proposal, but, ****** show of closing with her, despatched the messenger with thanks and expressions of joy, but dissuaded her earnestly from procuring herself to miscarry, which would impair her health, if not endanger her life; he himself, he said, would see to it, that the child, as soon as born, should be taken out of the way. By such artifices having drawn on the woman to the time of her lying-in, as soon as he heard that she was in labour, he sent persons to be by and observe all that passed, with orders that if it were a girl they should deliver it to the women, but if a boy, should bring it to him wheresoever he were, and whatsoever doing. It fell out that when he was at supper with the principal magistrates the queen was brought to bed of a boy, who was soon after presented to him as he was at the table; he, taking him into his arms, said to those about him, "Men of Sparta, here is a king born unto us;" this said, he laid him down in the king's place, and named him Charilaus, that is, the joy of the people; because that all were transported with joy and with wonder at his noble and just spirit. His reign had lasted only eight months, but he was honoured on other accounts by the citizens, and there were more who obeyed him because of his eminent virtues, than because he was regent to the king and had the royal power in his hands. Some, however, envied and sought to impede his growing influence while he was still young; chiefly the kindred and friends of the queen-mother, who pretended to have been dealt with injuriously.
Her brother Leonidas, in a warm debate which fell out betwixt him and Lycurgus, went so far as to tell him to his face that he was well assured that ere long he should see him king; suggesting suspicions and preparing the way for an accusation of him, as though he had made away with his nephew, if the child should chance to fail, though by a natural death. Words of the like import were designedly cast abroad by the queen-mother and her adherents.
Troubled at this, and not knowing what it might come to, he thought it his wisest course to avoid their envy by a voluntary exile, and to travel from place to place until his nephew came to marriageable years, and, by having a son, had secured the succession; setting sail, therefore, with this resolution, he first arrived at Crete, where, having considered their several forms of government, and got an acquaintance with the principal men among them, some of their laws he very much approved of, and resolved to make use of them in his own country; a good part he rejected as useless.
Among the persons there the most renowned for their learning and their wisdom in state matters was one Thales, whom Lycurgus, by importunities and assurances of friendship, persuaded to go over to Lacedaemon; where, though by his outward appearance and his own profession he seemed to be no other than a lyric poet, in reality he performed the part of one of the ablest lawgivers in the world. The very songs which he composed were exhortations to obedience and concord, and the very measure and cadence of the verse, conveying impressions of order and tranquillity, had so great an influence on the minds of the listeners, that they were insensibly softened and civilized, insomuch that they renounced their private feuds and animosities, and were reunited in a common admiration of virtue. So that it may truly be said that Thales prepared the way for the discipline introduced by Lycurgus.
