It has been suspected that the cause which drew this universal attention to an object apparently of very slight moment was, that the quarrel turned upon political principles; that the oligarchy at Eretria had very early given way to democracy, while that of Chalcis, threatened by this new danger, engaged many states to espouse its cause. We are informed indeed that the Eretrian oligarchy was overthrown by a person named Diagoras, of whom we also hear that he died at Corinth while on his way to Sparta, and that he was honoured with a statue by his countrymen. It is also certain that the oligarchy at Chalcis, though more than once interrupted by a tyranny, was standing till within a few years of the Persian wars. But we do not know when Diagoras lived, and, without stronger evidence, it is difficult to believe that the revolution which he effected took place before the fall of the Athenian aristocracy, an epoch which appears to be too late for the war mentioned by Thucydides.
THESSALY
Thessaly seems, for some time after the conquest, to have been governed by kings of the race of Hercules, who however may have been only chiefs invested with a permanent military command, which ceased when it was no longer required by the state of the country. Under one of these princes, named Aleuas, it was divided into the four districts, Thessaliotis, Pelasgiotis, Pthiotis, and Hestiæotis. And, as this division was retained to the latest period of its political existence, we may conclude that it was not a merely nominal one, but that each district was united in itself, as well as distinct from the rest. As the four Bœotian councils seem to imply that a like division existed in Bœotia, so we may reasonably conjecture that each of the Thessalian districts regulated its internal affairs by some kind of provincial council. But all that we know with certainty is, that the principal cities exercised a dominion over several smaller towns, and that they were themselves the seat of noble families, sprung from the line of the ancient kings, which were generally able to draw the government of the whole nation into their hands. Thus Larissa was subject to the great house of the Aleuadæ, who were considered as descendants of the ancient Aleuas; Crannon and Pharsalus to the Scopadæ and the Creondæ, who were branches of the same stock. The vast estates of these nobles were cultivated, and their countless flocks and herds fed, by their serfs, the Penests, who at their call were ready to follow them into the field on foot or on horseback. They maintained a princely state, drew poets and artists to their courts, and shone in the public games of Greece by their wealth and liberality.
We are not anywhere informed whether there were any institutions which provided for the union of the four districts, and afforded regular opportunities for consultation on their common interests. But, as often as an occasion appeared to require it, the great families were able to bring about the election of a chief magistrate, always of course taken from their own body, whose proper title was that of
