A general assembly of all the Greeks being called, Aristides proposed a decree that the deputies and religious representatives of the Greek states should assemble annually at Plataea, and every fifth year celebrate the Eleutheria or games of *******. And that there should be a levy upon all Greece for the war against the barbarians of ten thousand spearmen, one thousand horse, and a hundred sail of ships; but the Plataeans to be exempt, and sacred to the service of the gods, offering sacrifice for the welfare of Greece.
These things being ratified, the Plataeans undertook the performance of annual sacrifice to such as were slain and buried in that place;which they still perform in the following manner. On the sixteenth day of Maemacterion (which with the Boeotians is Alalcomenus) they make their procession, which, beginning by break of day, is led by a trumpeter sounding for onset; then follow certain chariots loaded with myrrh and garlands; and then a black bull; then come the young men of free birth carrying libations of wine and milk in large two-handed vessels, and jars of oil and precious ointments, none of servile condition being permitted to have any hand in this ministration, because the men died in defence of *******; after all comes the chief magistrate of Plataea (for whom it is unlawful at other times either to touch iron or wear any other coloured garment but white), at that time apparelled in a purple robe; and, taking a water-pot out of the city record-office, he proceeds, bearing a sword in his hand, through the middle of the town to the sepulchres.
Then drawing water out of a spring, he washes and anoints the monuments, and sacrificing the bull upon a pile of wood, and ****** supplication to Jupiter and Mercury of the earth, invites those valiant men who perished in the defence of Greece to the banquet and the libations of blood. After this, mixing a bowl of wine, and pouring out for himself, he says, "I drink to those who lost their lives for the liberty of Greece." These solemnities the Plataeans observe to this day.
Aristides perceived that the Athenians, after their return into the city, were eager for a democracy; and deeming the people to deserve consideration on account of their valiant behaviour, as also that it was a matter of difficulty, they being well armed, powerful, and full of spirit with their victories, to oppose them by force, he brought forward a decree that every one might share in the government and the archons be chosen out of the whole body of the Athenians. And on Themistocles telling the people in assembly that he had some advice for them, which could not be given in public, but was most important for the advantage and security of the city, they appointed Aristides alone to hear and consider it with him. And on his acquainting Aristides that his intent was to set fire to the arsenal of the Greeks, for by that means should the Athenians become supreme masters of all Greece, Aristides, returning to the assembly, told them that nothing was more advantageous than what Themistocles designed, and nothing more unjust. The Athenians, hearing this, gave Themistocles order to desist; such was the love of justice felt by the people, and such the credit and confidence they reposed in Aristides.
