Tyrant or patriot, as you will, in his own city of Pheræ, Jason had proceeded to bring most of the Thessalian cities, some by policy, some by arms, under that kind of subjection which so commonly in Greece was entitled confederacy. The strength of Pharsalus, directed by the abilities of Polydamas, was exerted to protect them. But Pharsalus itself was threatened, when Jason sent a proposal for a conference with the chief, which was accepted. In this conference the Pheræan avowed his “intention to reduce Pharsalus, and the towns dependent upon Pharsalus, to dependency upon himself;” but declared that “it was his wish to effect this rather by negotiation than by violence, and with benefit to Polydamas, rather than to his injury. It was in the power of Polydamas,” he said, “to persuade the Pharsalians; but that it was not in his power to defend them, the result of all his recent efforts sufficiently showed. For himself, he was resolved to hold the first situation in Greece; the second he offered to Polydamas. What their advantages would be, if a political union took place, Polydamas as well as himself could estimate.
“The cavalry of Thessaly was six thousand strong: the heavy-armed infantry exceeded ten thousand; the numerous inhabitants of the surrounding mountains, subjects of the Thessalian cities, were excellent targeteers. In addition to this force then he had six thousand mercenaries in his pay; a body such as, for choice of men, and perfection of discipline, no commonwealth of Greece possessed. But connection with Athens did not suit his views; for the Athenians affected to be the first maritime power of Greece, and he meant to make Thessaly the first. The three necessaries to naval power were timber, hands, and revenue. With the former, Athens was supplied from Macedonia, which lay much more conveniently for the supply of Thessaly. With the second their Penestian subjects were a resource to which Athens had nothing equal.” (The Penestæ were a conquered people, reduced to a kind of vassalage under the Thessalians, for whom they performed menial and laborious offices, but were not held in a slavery so severe and degrading as the helots of Laconia, for we find them admitted to that military service, the cavalry, which was generally reckoned among the Greeks to assort only with rank above the lowest citizens.)
It had been a practice of the Thessalian republics, always acknowledging some common bonds of union, to appoint, for extraordinary occasions a common military commander, a captain-general of the Thessalian nation, with the title of Tagus. To this high rank and great command Jason aspired, and the approbation of the Pharsalian government, it appears, was necessary. But he was far from so confining his views. Even the command of all Greece did not suffice for his ambition. “That all Greece might be reduced under their dominion,” he observed to Polydamas, “appeared probable from what he had already stated: but he conceived the conquest of the Persian empire to be a still easier achievement; the practical proof afforded by the return of the Cyrean Greeks, and by the great progress made with a very small force by Agesilaus, leaving this no longer a matter of mere speculation.”
Polydamas, in reply, admitted the justness of Jason’s reasoning; but alleged his own connection with Lacedæmon, which he would at no rate betray, as an objection that appeared to him insuperable. Jason, commending his fidelity to his engagements, freely consented that he should go to Lacedæmon and state his circumstances; and if he could not obtain succour which might give him reasonable hope of successful resistance, then he would stand clearly excused, both to his allies and to his fellow-citizens, in accepting the proposal offered him. Polydamas, returning then into Thessaly, requested and obtained from Jason, that he should hold under his own peculiar command the citadel of Pharsalus, which had been, in a manner so honourable to him, entrusted to his charge. For security of his fidelity to his new engagements, he surrendered his children as hostages. The Pharsalians, persuaded to acquiesce, were admitted to terms of peace and friendship by Jason, who was then elected without opposition tagus of Thessaly.
