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 rigor of the monarchy, seeking favor 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 endeavoring to quell a riot, he was stabbed with a butcher's knife, and left the title of king to his eldest son Polydectes.
