I. THE IONIC REVOLT.

Like the Lydians, the Persians ruled the Greek colonies with a degree of moderation, and permitted them to retain their own form of government by paying tribute; yet the Greeks seized every opportunity to deliver themselves from this species of thraldom, and in 502 B.C. an insurrection broke out in one of the Ionian states, which soon assumed a formidable character. Before the Persians could collect sufficient forces to quell the revolt, the Ionians sought the aid of their Grecian countrymen, making application first to Sparta, but in vain, and then to Athens and the islands of the Ægean Sea. The Athenians, regarding Darius as an avowed enemy, gladly took part with the Ionians, and, in connection with Euboe'a, furnished them a fleet of twenty-five vessels. The allied Grecians, though at first successful, were defeated near Ephesus with great loss. Their commanders then quarreled, and the Athenians sailed for home, leaving the Asiatic Greeks (divided among themselves) to contend alone against the whole power of Persia. Still, the revolt attained to considerable proportions, and was protracted during a period of six years. It was terminated by the capture of Miletus, the capital of the Ionian Confederacy, in 495 B.C. The inhabitants of this city who escaped the sword were carried into captivity by the conquerors, and the subjugation of Ionia was complete.

The principal achievement of the allied Grecians during this war was the burning of Sardis, the capital of the old Lydian monarchy. When Darius was informed of it he burst into a paroxysm of rage, directing his wrath chiefly against the Athenians and Euboeans who had dared to invade his dominions. "The Athenians!" he exclaimed, "who are they?" Upon being told, he took his bow and shot an arrow high into the air, saying, "Grant me, Jove, to take vengeance upon the Athenians." He also charged one of his attendants to call aloud to him thrice every day at dinner, "Sire, remember the Athenians!" As soon, therefore, as Darius had satisfied his vengeance against the Greek cities and islands of Asia, he turned his attention to the Athenians and Euboeans, in pursuance of his vow. He meditated, however, nothing less than the conquest of all Greece; but the Persian fleet that was to aid in carrying out his plans was checked in its progress, off Mount Athos, by a storm so violent that it is said to have destroyed three hundred vessels and over twenty thousand lives; and his son-in-law, Mardo'nius, who had entered Thrace and Macedon at the head of a large army, abruptly terminated his campaign and recrossed the Hellespont to Asia.

II. THE FIRST PERSIAN WAR.

Darius, having renewed his preparations for the conquest of Greece, sent heralds through the Grecian cities, demanding earth and water as tokens of submission. Some of the smaller states, intimidated by his power, submitted; but Athens and Sparta haughtily rejected the demands of the Eastern monarch, and put his heralds to death with cruel mockery, throwing one into a pit and another into a well, and bidding them take thence their earth and water.

In the spring of 490 B.C. a Persian fleet of six hundred ships, conveying an army of 120,000 men, and guided by the aged tyrant Hippias, directed its course toward the shores of Greece. Several islands of the Ægean submitted without a struggle. Euboea was severely punished; and with but little opposition the Persian host landed and advanced to the plains of Marathon, within twenty miles of Athens. The Athenians called on the Platæans and the Spartans for aid, and the former sent their entire force of one thousand men; but the Spartans refused to give the much-needed help, because it lacked a few days of the full moon, and it was contrary to their religious customs to begin a march during this interval. Meantime the Athenians had marched to Marathon, and were encamped on the hills that surrounded the plain. Their army numbered ten thousand men, and was commanded by Callim'achus, the Pol'emarch or third Archon, and ten generals, among whom were Milti'ades, Themis'tocles, and Aristi'des, who subsequently acquired immortal fame. Five of the ten generals were afraid to hazard a battle without the aid of the Spartans; but the arguments of Miltiades finally prevailed upon Callimachus to give his casting vote in favor of immediate action. Although the ten generals were to command the whole army successively, each for one day, it was agreed to invest Miltiades with the command at once, and intrust to his military skill the fortunes of Athens. He immediately drew up the little army in order of battle.

THE BATTLE OF MARATHON.

The Persians were extended in a line across the middle of the plain, having their best troops in the center, while their fleet was ranged behind them along the beach. The Athenians were drawn up in a line opposite, but having their main strength in the extreme wings of their army. Miltiades quickly advanced his force across the mile of plain that separated it from the foe, and fell upon the immense army of the Persians. As he had foreseen, the center of his line was soon broken, while the extremities of the enemy's line, made up of motley and undisciplined bands of all nations, were routed and driven toward the shore, and into the adjoining morasses. Miltiades now hastily concentrated his two wings and directed their united force against the Persian center, which, deeming itself victorious, was taken completely by surprise. The Persians, defeated, fled in disorder to their ships, but many perished in the marshes; the shore was strewn with their dead, and seven of their ships were destroyed. Their loss was six thousand four hundred; that of the Athenians, not including the Platæans, only one hundred and ninety two. Such, in brief, was the famous battle of Marathon. The Persians were strong in the terror of their name, and in the renown of their conquests; and it required a most heroic resolution in the Athenians to face a danger that they had not yet learned to despise.

LEGENDS OF THE BATTLE.

The victory at Marathon was viewed by the people as a deliverance by the gods themselves. It is fabled that before the battle the voice of the god Pan was heard in the mountains, uttering warnings and threatenings to the Persians, and inspiring the Greeks with courage. Hence the wonderful legends of the battle, in which Theseus, Hercules, and other local heroes are represented as engaging in the combat, and dealing death among the flying barbarians. In the following lines MRS. HEMANS has embraced the description which the Greeks gave of the appearance and deeds of Theseus on that occasion:
