Aratus laughing at the jest, and asking what manner of youth this was, Damocrates, a Spartan exile, replied, "If you have any designs upon the Lacedaemonians, begin before this young eagle's talons are grown." Presently after this, Cleomenes, encamping in Arcadia with a few horse and three hundred foot, received orders from the ephors, who feared to engage in the war, commanding him to return home; but when upon his retreat Aratus took Caphyae, they commissioned him again.
In this expedition he took Methydrium, and overran the country of the Argives; and the Achaeans, to oppose him, came out with an army of twenty thousand foot and one thousand horse, under the command of Aristomachus. Cleomenes faced them at Pallantium, and offered battle, but Aratus, being cowed by his bravery, would not suffer the general to engage, but retreated amidst the reproaches of the Achaeans and the derision and scorn of the Spartans, who were not above five thousand. Cleomenes, encouraged by this success, began to speak boldly among the citizens, and reminding them of a sentence of one of their ancient kings, said, it was in vain now that the Spartans asked not how many their enemies were, but where they were. After this, marching to the assistance of the Eleans, whom the Achaeans were attacking, falling upon the enemy in their retreat near the Lycaeum, he put their whole army to flight, taking a great number of captives, and leaving many dead upon the place; so that it was commonly reported amongst the Greeks that Aratus was slain. But Aratus, ****** the best advantage of the opportunity, immediately after the defeat marched to Mantinea, and before anybody suspected it, took the city, and put a garrison into it. Upon this, the Lacedaemonians being quite discouraged, and opposing Cleomenes's designs of carrying on the war, he now exerted himself to have Archidamus, the brother of Agis, sent for from Messene, as he, of the other family, had a right to the kingdom; and besides, Cleomenes thought that the power of the ephors would be reduced, when the kingly state was thus filled up, and raised to its proper position. But those that were concerned in the murder of Agis, perceiving the design, and fearing that upon Archidamus's return that they should be called to an account, received him on his coming privately into town, and joined in bringing him home, and presently after murdered him. Whether Cleomenes was against it, as Phylarchus thinks, or whether he was persuaded by his friends, or let him fall into their hands, is uncertain; however, they were most blamed, as having forced his consent.
He, still resolving to new model the state, bribed the ephors to send him out to war; and won the affections of many others by means of his mother Cratesiclea, who spared no cost and was very zealous to promote her son's ambition; and though of herself she had no inclination to marry, yet for his sake she accepted, as her husband, one of the chiefest citizens for wealth and power. Cleomenes, marching forth with the army now under his command, took Leuctra, a place belonging to Megalopolis; and the Achaeans quickly coming up to resist him with a good body of men commanded by Aratus, in a battle under the very walls of the city, some part of his army was routed. But whereas Aratus had commanded the Achaeans not to pass a deep watercourse, and thus put a stop to the pursuit, Lydiadas, the Megalopolitan, fretting at the orders, and encouraging the horse which he led, and following the routed enemy, got into a place full of vines, hedges, and ditches; and being forced to break his ranks, began to retire in disorder. Cleomenes, observing the advantage, commanded the Tarentines and Cretans to engage him, by whom, after a brave defence, he was routed and slain. The Lacedaemonians, thus encouraged, fell with a great shout upon the Achaeans, and routed their whole army. Of the slain, who were very many, the rest Cleomenes delivered up, when the enemy petitioned for them; but the body of Lydiadas he commanded to be brought to him; and then putting on it a purple robe, and a crown upon its head, sent a convoy with it to the gates of Megalopolis. This is that Lydiadas who resigned his power as tyrant, restored liberty to the citizens, and joined the city to the Achaean interest.
Cleomenes, being very much elated by this success, and persuaded that if matters were wholly at his disposal he should soon be too hard for the Achaeans, persuaded Magistonus, his mother's husband, that it was expedient for the state to shake off the power of the ephors, and to put all their wealth into one common stock for the whole body; thus Sparta, being restored to its old equality, might aspire again to the command of all Greece. Megistonas liked the design, and engaged two or three more of his friends. About that time, one of the ephors, sleeping in Pasiphaes temple, dreamed a very surprising dream; for he thought he saw the four chairs removed out of the place where the ephors used to sit and do the business of their office, and one only set there; and whilst he wondered, he heard a voice out of the temple, saying, "This is best for Sparta." The person telling Cleomenes this dream, he was a little troubled at first, fearing that he used this as a trick to sift him, upon some suspicion of his design, but when he was satisfied that the relator spoke truth, he took heart again. And carrying with him those whom he thought would be most against his project, he took Heraea and Alsaea two towns in league with the Achaeans, furnished Orchomenus with provisions, encamped before Mantinea, and with long marches up and down so harassed the Lacedaemonians that many of them at their own request were left behind in Arcadia, while he with the mercenaries went on toward Sparta, and by the way communicated his design to those whom he thought fitted for his purpose, and marched slowly, that he might catch the ephors at supper.
