The first requisition addressed by the Lacedæmonians to Athens was a political manœuvre aimed at Pericles, their chief opponent in that city. His mother Agariste belonged to the great family of the Alemæonids, who were supposed to be under an inexorable hereditary taint, in consequence of the sacrilege committed by their ancestor Megacles nearly two centuries before, in the slaughter of the Cylonian suppliants near the altar of the Venerable Goddesses. Ancient as this transaction was, it still had sufficient hold on the mind of the Athenians to serve as the basis of a political manœuvre: about seventy-seven years before, shortly after the expulsion of Hippias from Athens, it had been so employed by the Spartan king Cleomenes, who at that time exacted from the Athenians a clearance of the ancient sacrilege, to be effected by the banishment of Clisthenes (the founder of the democracy) and his chief partisans. This demand, addressed by Cleomenes to the Athenians at the instance of Isagoras, the rival of Clisthenes, had been then obeyed, and had served well the purposes of those who sent it. A similar blow was now aimed by the Lacedæmonians at Pericles (the grand-nephew of Clisthenes), and doubtless at the instance of his political enemies: religion required, it was pretended, that “the abomination of the goddess should be driven out.” If the Athenians complied with this demand, they would deprive themselves, at this critical moment, of their ablest leader. But the Lacedæmonians, not expecting compliance, reckoned at all events upon discrediting Pericles with the people, as being partly the cause of the war through family taint of impiety; and this impression would doubtless be loudly proclaimed by his political opponents in the assembly.
The influence of Pericles with the Athenian public had become greater and greater as their political experience of him was prolonged. But the bitterness of his enemies appears to have increased along with it; and not long before this period, he had been indirectly assailed, as we have seen, through the medium of accusations against three different persons, all more or less intimate with him—his mistress Aspasia, the philosopher Anaxagoras, and the sculptor Phidias. It is said also that Dracontides proposed and carried a decree in the public assembly, that Pericles should be called on to give an account of the money which he had expended, and that the dicasts, before whom the account was rendered, should give their suffrage in the most solemn manner from the altar: this latter provision was modified by Agnon, who, while proposing that the dicasts should be fifteen hundred in number, retained the vote by pebbles in the urn according to ordinary custom.
If Pericles was ever tried on such a charge, there can be no doubt that he was honourably acquitted: for the language of Thucydides respecting his pecuniary probity is such as could not have been employed if a verdict of guilty on a charge of peculation had been publicly pronounced. But we cannot be certain that he ever was tried; indeed, another accusation urged by his enemies, and even by Aristophanes in the sixth year of the Peloponnesian War, implies that no trial took place: for it was alleged that Pericles, in order to escape this danger, “blew up the Peloponnesian War,” and involved his country in such confusion and peril as made his own aid and guidance indispensably necessary to her, especially that he passed the decree against the Megarians by which the war was really brought on. We know enough, however, to be certain that such a supposition is altogether inadmissible. The enemies of Pericles were far too eager, and too expert in Athenian political warfare, to have let him escape by such a stratagem. Moreover, we learn from the assurance of Thucydides that the war depended upon far deeper causes—that the Megarian decree was in no way the real cause of it; that it was not Pericles, but the Peloponnesians, who brought it on, by the blow struck at Potidæa.
