When he perceived that his more important institutions had taken root in the minds of his countrymen, that custom had rendered them familiar and easy, that his commonwealth was now grown up and able to go alone, then, as Plato somewhere tells us the Maker of the world, when first he saw it existing and beginning its motion, felt joy, even so Lycurgus, viewing with joy and satisfaction the greatness and beauty of his political structure, now fairly at work and in motion, conceived the thought to make it immortal too, and as far as human forecast could reach, to deliver it down unchangeable to posterity. He called an extraordinary assembly of all the people, and told them that he now thought everything reasonably well established, both for the happiness and the virtue of the state; but that there was one thing still behind, of the greatest importance, which he thought not fit to impart until he had consulted the oracle; in the meantime, his desire was that they would observe the laws without even the least alteration until his return, and then he would do as the god should direct him. They all consented readily, and bade him hasten his journey; but, before he departed, he administered an oath to the two kings, the senate, and the whole commons, to abide by and maintain the established form of polity until Lycurgus should come back. This done, he set out for Delphi, and, having sacrificed to Apollo, asked him whether the laws he had established were good and sufficient for a people's happiness and virtue. The oracle answered that the laws were excellent, and that the people, while it observed them, should live in the height of renown. Lycurgus took the oracle in writing, and sent it over to Sparta, and, having sacrificed a second time to Apollo, and taken leave of his friends and his son, he resolved that the Spartans should not be released from the oath they had taken, and that he would, of his own act, close his life where he was. He was now about that age in which life was still tolerable, and yet might be quitted without regret. Everything, moreover, about him was in a sufficiently prosperous condition. He, therefore, made an end of himself by a total abstinence from food; thinking it a statesman's duty to make his very death, if possible, an act of service to the state, and even in the end of his life to give some example of virtue and effect some useful purpose. Nor was he deceived in his expectations, for the city of Lacedaemon continued the chief city of all Greece for the space of five hundred years, in strict observance of Lycurgus's laws; in all which time there was no manner of alteration made, during the reign of fourteen kings, down to the time of Agis, the son of Archidamus.
