I. The dawning spring and the formidable appearance of Mardonius, who, with his Persian forces, diminished indeed, but still mighty, lowered on their confines, aroused the Greeks to a sense of their danger. Their army was not as yet assembled, but their fleet, consisting of one hundred and ten vessels, under the command of Leotychides, king of Sparta, and Xanthippus of Athens, lay off Aegina. Thus anchored, there came to the naval commanders certain Chians, who, having been discovered in a plot against the life of Strattis, a tyrant imposed upon Chios by the Persians, fled to Aegina. They declared that all Ionia was ripe for revolt, and their representations induced the Greeks to advance as far as the sacred Delos. Beyond they dared not venture, ignorant alike of the localities of the country and the forces of the enemy. Samos seemed to them no less remote than the Pillars of Hercules, and mutual fear thus kept the space between the Persian and the Greek fleet free from the advance of either. But Mardonius began slowly to stir from his winter lethargy. Influenced, thought the Greeks, perhaps too fondly, by a Theban oracle, the Persian general despatched to Athens no less distinguished an ambassador than Alexander, the king of Macedon. That prince, connected with the Persians by alliance (for his sister had married the Persian Bubares, son of Megabazus), was considered an envoy calculated to conciliate the Athenians while he served their enemy. And it was now the object of Mardonius to reconcile the foe whom he had failed to conquer. Aware of the Athenian valour, Mardonius trusted that if he could detach that state from the confederacy, and prevail on the Athenians to unite their arms to his own, the rest of Greece would become an easy conquest. By land he already deemed himself secure of fortune, by sea what Grecian navy, if deprived of the flower of its forces, could resist him? II. The King of Macedon arrived at Athens; but conscious of the jealous and anxious fear which the news of an embassy from Persia would excite among the confederates, the Athenians delayed to grant him the demanded audience until they had time to send for and obtain deputies from Sparta to be present at the assembly. Alexander of Macedon then addressed the Athenians. "Men of Athens!" said he, "Mardonius informs you, through me, of this mandate from the king: 'Whatever injuries,' saith he, 'the Athenians have done me, I forgive. Restore them their country--let them even annex to it any other territories they covet--permit them the free enjoyment of their laws. If they will ally with me, rebuild the temples I have burnt.'" Alexander then proceeded to dilate on the consequences of this favourable mission, to represent the power of the Persian, and urge the necessity of an alliance. "Let my offers prevail with you," he concluded, "for to you alone, of all the Greeks, the king extends his forgiveness, desiring your alliance."
