People would not then tolerate natural philosophers, and theorists, as they then called them, about things above; as lessening the divine power, by explaining away its agency into the operation of irrational causes and senseless forces acting by necessity, without anything of Providence or a free agent. Hence it was that Protagoras was banished, and Anaxagoras cast in prison, so that Pericles had much difficulty to procure his liberty; and Socrates, though he had no concern whatever with this sort of learning, yet was put to death for philosophy. It was only afterwards that the reputation of Plato, shining forth by his life, and because he subjected natural necessity to divine and more excellent principles, took away the obloquy and scandal that had attached to such contemplations, and obtained these studies currency among all people. So his friend Dion, when the moon, at the time he was to embark from Zacynthus to go against Dionysius, was eclipsed, was not in the least disturbed, but went on, and arriving at Syracuse, expelled the tyrant. But it so fell out with Nicias, that he had not at this time a skilful diviner with him; his former habitual adviser who used to moderate much of his superstition, Stilbides, had died a little before. For, in fact, this prodigy, as Philochorus observes, was not unlucky for men wishing to fly, but on the contrary very favourable; for things done in fear require to be hidden, and the light is their foe. Nor was it usual to observe signs in the sun or moon more than three days, as Autoclides states in his Commentaries. But Nicias persuaded them to wait another full course of the moon, as if he had not seen it clear again as soon as ever it had passed the region of shadow where the light was obstructed by the earth.
In a manner abandoning all other cares, he betook himself wholly to his sacrifices, till the enemy came upon them with their infantry, besieging the forts and camp, and placing their ships in a circle about the harbour. Nor did the men in the galleys only, but the little boys everywhere got into the fishing-boats and rowed up and challenged the Athenians, and insulted over them. Amongst these a youth of noble parentage, Heraclides by name, having ventured out beyond the rest, an Athenian ship pursued and well-nigh took him.
His uncle Pollichus, in fear for him, put out with ten galleys which he commanded, and the rest, to relieve Pollichus, in like manner drew forth; the result of it being a very sharp engagement, in which the Syracusans had the victory, and slew Eurymedon, with many others. After this the Athenian soldiers had no patience to stay longer, but raised an outcry against their officers, requiring them to depart by land; for the Syracusans, upon their victory, immediately shut and blocked up the entrance of the harbour; but Nicias would not consent to this, as it was a shameful thing to leave behind so many ships of burden, and galleys little less than two hundred.
Putting, therefore, on board the best of the foot, and the most serviceable darters, they filled one hundred and ten galleys; the rest wanted oars. The remainder of his army Nicias posted along by the seaside, abandoning the great camp and the fortifications adjoining the temple of Hercules; so the Syracusans, not having for a long time performed their usual sacrifice to Hercules, went up now, both priests and captains, to sacrifice.
And their galleys being manned, the diviners predicted from their sacrifices victory and glory to the Syracusans, provided they would not be the aggressors, but fight upon the defensive; for so Hercules overcame all, by only defending himself when set upon. In this confidence they set out; and this proved the hottest and fiercest of all their sea-fights, raising no less concern and passion in the beholders than in the actors; as they could oversee the whole action with all the various and unexpected turns of fortune which, in a short space, occurred in it; the Athenians suffering no less from their own preparations, than from the enemy; for they fought against light and nimble ships, that could attack from any quarter, with theirs laden and heavy. And they were thrown at with stones that fly indifferently any way, for which they could only return darts and arrows, the direct aim of which the motion of the water disturbed, preventing their coming true, point foremost to their mark. This the Syracusans had learned from Ariston the Corinthian pilot, who, fighting stoutly, fell himself in this very engagement, when the victory had already declared for the Syracusans.
The Athenians, their loss and slaughter being very great, their flight by sea cut off, their safety by land so difficult, did not attempt to hinder the enemy towing away their ships, under their eyes, nor demanded their dead, as, indeed, their want of burial seemed a less calamity than the leaving behind the sick and wounded which they now had before them. Yet more miserable still than those did they reckon themselves, who were to work on yet, through more such sufferings, after all to reach the same end.
