"Fortunately for Sparta, the danger was not altogether unforeseen. After the confusion and the horror of the earthquake, and while the people, dispersed, were seeking to save their effects, Archida'mus, who, four years before, had succeeded to the throne of Lacedæmon, ordered the trumpets to sound as to arms. That wonderful superiority of man over matter which habit and discipline can effect, and which was ever so visible among the Spartans, constituted their safety at that hour. Forsaking the care of their property, the Spartans seized their arms, flocked around their king, and drew up in disciplined array. In her most imminent crisis Sparta was thus saved. The Helots approached, wild, disorderly, and tumultuous; they came intent only to plunder and to slay; they expected to find scattered and affrighted foes --they found a formidable army; their tyrants were still their lords. They saw, paused, and fled, scattering themselves over the country, exciting all they met to rebellion, and soon joined with the Messenians, kindred to them by blood and ancient reminiscences of heroic struggles; they seized that same Ithome which their hereditary Aristodemus had before occupied with unforgotten valor. This they fortified, and, occupying also the neighboring lands, declared open war upon their lords." [Footnote: "Athens: Its Rise and Fall," pp. 176, 177.] "The incident here related of the King of Sparta," says ALISON, "amid the yawning of the earthquake and the ruin of his capital, sounding the trumpets to arms, and the Lacedæmonians assembling in disciplined array around him, is one of the sublimest recorded in history. We need not wonder that a people capable of such conduct in such a moment, and trained by discipline and habit to such docility in danger, should subsequently acquire and maintain supreme dominion in Greece." The general insurrection of the Helots is known in history as the THIRD MESSENIAN WAR. After two or three years had passed in vain attempts to capture Ithome, the Spartans were obliged to call for aid on the Athenians, with whom they were still in avowed alliance. The friends of Pericles, the rival of Cimon and the leader of the democratic party at Athens, opposed granting the desired relief; but Cimon, after some difficulty, persuaded his countrymen to assist the Lacedæmonians, and he himself marched with four thousand men to Ithome. The aid of the Athenians was solicited on account of their acknowledged skill in capturing fortified places; but as Cimon did not succeed in taking Ithome, the Spartans became suspicious of his designs, and summarily sent him back to Athens. * * * * * III.
