XXI. But even conquest had not sufficed to remove the jealousies of the confederate leaders--they evaded the decision of a question which could not but be propitious to the Athenians, and returned home without having determined the point which had assembled them at the isthmus. But Themistocles was not of a temper to brook patiently this fraud upon his honours. Far from sharing the petty and miserable envies of their chiefs, the Greeks generally were loud in praise of his wisdom and services; and, taking advantage of their enthusiasm, Themistocles repaired to Sparta, trusting to the generosity of the principal rival to compensate the injustice of many. His expectations were not ill-founded--the customs of Sparta allowed no slight to a Spartan, and they adjudged therefore the prize of valour to their own Eurybiades, while they awarded that of wisdom or science to Themistocles. Each was equally honoured with a crown of olive. Forgetful of all their prejudices, their envy, and their inhospitable treatment of strangers, that nation of warriors were dazzled by the hero whose courage assimilated to their own. They presented him with the stateliest chariot to be found in Sparta, and solemnly conducted him homeward as far as Tegea, by an escort of three hundred chosen Spartans called "The Knights"--the sole example of the Spartans conducting any man from their city. It is said that on his return to Athens, Themistocles was reproached by Timodemus of Aphidna, a Belbinite by origin [92], and an implacable public enemy, with his visit to Sparta: "The honours awarded you," said Timodemus, "are bestowed from respect, not to you, but to Athens." "My friend," retorted the witty chief, "the matter stands thus. Had I been a Belbinite, I had not been thus distinguished at Sparta, nor would you, although you had been born an Athenian!" While the Greeks were thus occupied, the Persian army had retreated with Mardonius into Thessaly. Here that general selected and marshalled the forces with which he intended to renew the war, retaining in his service the celebrated Immortals. The total, including the cavalry, Herodotus estimates at three hundred thousand men. Thus occupied, and ere Xerxes departed from Thessaly, the Spartans, impelled by an oracle, sent a messenger to Xerxes to demand atonement for the death of Leonidas. "Ay," replied the king, laughing, "this man (pointing to Mardonius) shall make you fitting retribution."
