Egypt had been rather overrun by Xerxes than subdued—and the spirit of its ancient people waited only the occasion of revolt. A Libyan prince, of the name of Inarus, whose territories bordered Egypt, entered that country (B. C. 460), and was hailed by the greater part of the population as a deliverer. The recent murder of Xerxes—the weakness of a new reign, commenced in so sanguinary a manner, appeared to favour their desire of independence; and the African adventurer beheld himself at the head of a considerable force. Having already secured foreign subsidiaries, Inarus was anxious yet more to strengthen himself abroad; and more than one ambassador was despatched to Athens, soliciting her assistance, and proffering, in return, a share in the government for whose establishment her arms were solicited: a singular fatality, that the petty colony which, if we believe tradition, had so many centuries ago settled in the then obscure corners of Attica, should now be chosen the main auxiliary of the parent state in her vital struggles for national independence.

III. In acceding to the propositions of Inarus, Pericles yielded to considerations wholly contrary to his after policy, which made it a principal object to confine the energies of Athens within the limits of Greece. It is probable that that penetrating and scientific statesman (if indeed he had yet attained to a position which enabled him to follow out his own conceptions) saw that every new government must dazzle either by great enterprises abroad or great changes at home—and that he preferred the former. There are few sacrifices that a wary minister, newly-established, from whom high hopes are entertained, and who can justify the destruction of a rival party only by the splendour of its successor—will not hazard rather than incur the contempt which follows disappointment. He will do something that is dangerous rather than do nothing that is brilliant.

Neither the hatred nor the fear of Persia was at an end in Athens; and to carry war into the heart of her empire was a proposition eagerly hailed. The more democratic and turbulent portion of the populace, viz., the seamen, had already been disposed of in an expedition of two hundred triremes against Cyprus. But the distant and magnificent enterprise of Egypt—the hope of new empire—the lust of undiscovered treasures—were more alluring than the reduction of Cyprus. That island was abandoned, and the fleet, composed both of Athenian and confederate ships, sailed up the Nile. Masters of that river, the Athenians advanced to Memphis, the capital of Lower Egypt. They stormed and took two of the divisions of that city; the third, called the White Castle (occupied by the Medes, the Persians, and such of the Egyptians as had not joined the revolt), resisted their assault.

IV. While thus occupied in Egypt, the Athenian arms were equally employed in Greece. The whole forces of the commonwealth were in demand—war on every side. The alliance with Megara not only created an enemy in Corinth, but the Peloponnesian confederacy became involved with the Attic: Lacedaemon herself, yet inert, but menacing; while the neighbouring Aegina, intent and jealous, prepared for hostilities soon manifest.

The Athenians forestalled the attack—made a descent on Haliae, in Argolis—were met by the Corinthians and Epidaurians, and the result of battle was the victory of the latter. This defeat the Athenians speedily retrieved at sea. Off Cecryphalea, in the Saronic gulf, they attacked and utterly routed the Peloponnesian fleet. And now Aegina openly declared war and joined the hostile league. An important battle was fought by these two maritime powers with the confederates of either side. The Athenians were victorious—took seventy ships— and, pushing the advantage they had obtained, landed in Aegina and besieged her city. Three hundred heavy-armed Peloponnesians were despatched to the relief of Aegina; while the Corinthians invaded the Megarian territory, seized the passes of Geranea, and advanced to Megara with their allies. Never was occasion more propitious. So large a force in Egypt, so large a force at Aegina—how was it possible for the Athenians to march to the aid of Megara? They appeared limited to the choice either to abandon Megara or to raise the siege of Aegina: so reasoned the Peloponnesians. But the advantage of a constitution widely popular is, that the whole community become soldiers in time of need. Myronides, an Athenian of great military genius, not unassisted by Pericles, whose splendid qualities now daily developed themselves, was well adapted to give direction to the enthusiasm of the people. Not a man was called from Aegina. The whole regular force disposed of, there yet remained at Athens those too aged and those too young for the ordinary service. Under Myronides, boys and old men marched at once to the assistance of their Megarian ally. A battle ensued; both sides retiring, neither considered itself defeated. But the Corinthians retreating to Corinth, the Athenians erected a trophy on the field. The Corinthian government received its troops with reproaches, and, after an interval of twelve days, the latter returned to the scene of contest, and asserting their claim to the victory, erected a trophy of their own. During the work the Athenians sallied from Megara, where they had ensconced themselves, attacked and put to flight the Corinthians; and a considerable portion of the enemy turning into ground belonging to a private individual, became entangled in a large pit or ditch, from which was but one outlet, viz., that by which they had entered. At this passage the Athenians stationed their heavy-armed troops, while the light-armed soldiers surrounded the ditch, and with the missiles of darts and stones put the enemy to death. The rest (being the greater part) of the Corinthian forces effected a safe but dishonourable retreat.

V. This victory effected and Megara secured—although Aegina still held out, and although the fate of the Egyptian expedition was still unknown—the wonderful activity of the government commenced what even in times of tranquillity would have been a great and arduous achievement. To unite their city with its seaports, they set to work at the erection of the long walls, which extended from Athens both to Phalerus and Piraeus. Under Cimon, preparations already had been made for the undertaking, and the spoils of Persia now provided the means for the defence of Athens.

Meanwhile, the Spartans still continued at the siege of Ithome. We must not imagine that all the helots had joined in the revolt. This, indeed, would be almost to suppose the utter disorganization of the Spartan state. The most luxurious subjects of a despotism were never more utterly impotent in procuring for themselves the necessaries of life, than were the hardy and abstemious freemen of the Dorian Sparta. It was dishonour for a Spartan to till the land—to exercise a trade. He had all the prejudices against any calling but that of arms which characterized a noble of the middle ages.

As is ever the case in the rebellion of slaves, the rise was not universal; a sufficient number of these wretched dependants remained passive and inert to satisfy the ordinary wants of their masters, and to assist in the rebuilding of the town. Still the Spartans were greatly enfeebled, crippled, and embarrassed by the loss of the rest: and the siege of Ithome sufficed to absorb their attention, and to make them regard without open hostilities, if with secret enmity, the operations of the Athenians. The Spartan alliance formally dissolved —Megara, with its command of the Peloponnesus seized—the Doric city of Corinth humbled and defeated—Aegina blockaded; all these—the Athenian proceedings—the Spartans bore without any formal declaration of war.

VI. And now, in the eighth year of the Messenian war, piety succeeded where pride and revenge had failed, and the Spartans permitted other objects to divide their attention with the siege of Ithome. It was one of the finest characteristics of that singular people, their veneration for antiquity. For the little, rocky, and obscure territory of Doris, whence tradition derived their origin, they felt the affection and reverence of sons. A quarrel arising between the people of this state and the neighbouring Phocians, the latter invaded Doris, and captured one of its three towns [189]. The Lacedaemonians marched at once to the assistance of their reputed father-land, with an army of no less than fifteen hundred heavy-armed Spartans and ten thousand of their Peloponnesian allies [190], under the command of Nicomedes, son of Cleombrotus, and guardian of their king Pleistoanax, still a minor. They forced the Phocians to abandon the town they had taken; and having effectually protected Doris by a treaty of peace between the two nations, prepared to return home. But in this they were much perplexed; the pass of Geranea was now occupied by the Athenians: Megara, too, and Pegae were in their hands. Should they pass by sea through the Gulf of Crissa, an Athenian squadron already occupied that passage. Either way they were intercepted [191]. Under all circumstances, they resolved to halt a while in Boeotia, and watch an opportunity to effect their return. But with these ostensible motives for that sojourn assigned by Thucydides, there was another more deep and latent. We have had constant occasion to remark how singularly it was the Spartan policy to plot against the constitution of free states, and how well-founded was the Athenian jealousy of the secret interference of the Grecian Venice.

Halting now in Boeotia, Nicomedes entered into a clandestine communication with certain of the oligarchic party in Athens, the object of the latter being the overthrow of the existent popular constitution. With this object was certainly linked the recall of Cimon, though there is no reason to believe that great general a party in the treason. This conspiracy was one main reason of the halt in Boeotia. Another was, probably, the conception of a great and politic design, glanced at only by historians, but which, if successful, would have ranked among the masterpieces of Spartan statesmanship. This design was—while Athens was to be weakened by internal divisions, and her national spirit effectually curbed by the creation of an oligarchy, the tool of Sparta—to erect a new rival to Athens in the Boeotian Thebes. It is true that this project was not, according to Diodorus, openly apparent until after the battle of Tanagra. But such a scheme required preparation; and the sojourn of Nicomedes in Boeotia afforded him the occasion to foresee its possibility and prepare his plans. Since the Persian invasion, Thebes had lost her importance, not only throughout Greece, but throughout Boeotia, her dependant territory. Many of the states refused to regard her as their capital, and the Theban government desired to regain its power. Promises to make war upon Athens rendered the Theban power auxiliary to Sparta: the more Thebes was strengthened, the more Athens was endangered: and Sparta, ever averse to quitting the Peloponnesus, would thus erect a barrier to the Athenian arms on the very frontiers of Attica.
