The first object of Jason, in his high office, was to inquire concerning the force which the whole country, now acknowledging him its constitutional military commander, could furnish; and it was found to amount to more than eight thousand horse, full twenty thousand heavy-armed foot, and targeteers enough, in the contemporary historian’s phrase, for war with all the world. His next care was the revenue, which might enable him to give energy to this force. Jason was ambitious, but not avaricious, and he desired to have willing subjects. He required therefore from the dependent states around Thessaly only that tribute which had been formerly assessed under the tagus Scopas. At the time of the battle of Leuctra, Jason was already this formidable potentate, and he was then in alliance with Thebes. When therefore the Thebans sent to the Athenian people an account of that splendid action, they did not fail to communicate the intelligence also to the tagus of Thessaly; and they added a request for his co-operation towards the complete overthrow of the tyranny, so long exercised by the Lacedæmonians over the Greek nation. The circumstances were altogether such as Jason was not likely to look upon with indifference. Having ordered a fleet to be equipped, he put himself at the head of his mercenaries, his standing army, and taking the cavalry in the moment about him, he began his march. He reached Bœotia without loss; showing, as the contemporary historian observes, how despatch may often do more than force.
Jason, the ally of Thebes, was connected, not indeed by political alliance, but by public and hereditary hospitality, with Lacedæmon. Pleased with the humiliation of his hosts, he was not desirous that his allies should become too powerful. On reaching the Theban camp therefore, demurring to the proposal of the Theban generals for an immediate attack upon the Lacedæmonians, he became the counsellor of peace; and, acting as mediator, he quickly succeeded so far as to procure a truce. The Lacedæmonians hastened to use the opportunity for reaching a place of safety. Jason, after having thus acted as arbiter of Greece, hastened his return to Thessaly. In his way through the hostile province of Phocis, with leisure to exercise his vengeance, for which he had not before wanted strength, he confined it to the little town of Hyampolis, whose suburbs and territory he wasted, killing many of the people. The Lacedæmonian colony of Heraclea was then to be passed. He had served Lacedæmon at Leuctra because he thought it for his interest; and he would, without scruple, or fear, injure Lacedæmon, in its colony of Heraclea, because the prosperity of that colony would obstruct his views. Heraclea was most critically situated for commanding the only easily practicable communication between the countries northward and southward. He therefore demolished the fortifications.

Decidedly now the greatest potentate of Greece, powerful, not by his own strength alone, but by his numerous alliances, while on all sides his alliance was courted, Jason proposed to display his magnificence at the approaching Pythian games. He had commanded all the republics which owned the authority of the tagus of Thessaly to feed oxen, sheep, goats, and swine for the sacrifices; and he proposed the reward of a golden crown for the state which should produce the finest ox to lead the herd for the god. By a very easy impost on them severally, he collected more than a thousand oxen, and ten thousand smaller cattle. He appointed a day, a little before the festival, for assembling the military force of Thessaly; and the expectation in Greece was that he would assume to himself the presidency. Apprehension arose that he might seize the treasure of Delphi; insomuch that the Delphians consulted their oracle for directions from the god on the occasion. The answer, according to report, was similar to what had been given to their forefathers when Xerxes invaded Greece, “that the care of the treasure would be the god’s own concern.”
