Historians mention, as a proof of the singular virulence of this pestilence, that the birds of prey refused to touch the unburied bodies of its victims, and that the dogs which fed upon the poisonous relics perished. The mortality was dreadful, and was of course greatly increased by the overcrowded state of the city. The prayers of the devout, and the skill of the physicians, were found equally unavailing to stop the progress of the disease; and the miserable Athenians, reduced to despair, believed themselves to be forgotten or hated by their gods. The sick were in many cases left unattended, and the bodies of the dead allowed to lie unburied, while those whom the plague had not yet reached, openly sat at defiance all laws, human and divine, and rushed into every excess of criminal indulgence. Pericles was in the meantime engaged, with a fleet of 150 ships, in wasting with fire and sword the shores of Peloponnesus. At his return to Athens, finding that the enemy had hastily retired from Attica, through fear of the contagion of the plague, he despatched the fleet to the coast of Chalcidice, to assist the Athenian land forces who were still engaged in the siege of Potidæa――an unfortunate measure, productive of no other result than the communication of the pestilence to the besieging army, by which the majority of the troops were speedily swept away. Maddened by their sufferings, the Athenians now became loud in their murmurs against Pericles, whom they accused of having brought upon them at least a portion of their calamities, by involving them in the Peloponnesian war. An assembly of the people was held, in which Pericles entered upon a justification of his conduct and exhorted them to courage and perseverance in defense of their independence. The hardships to which they had been exposed by the war, were, he observed, only such as he had in former addresses prepared them to expect; and as for the pestilence, it was a calamity which no human prudence could either have foreseen or averted. He reminded them that they still possessed a fleet which that of no potentate on earth could equal or cope with, and that, after the present evil should have passed away, their navy might yet enable them to acquire universal empire. ‘What we suffer from the gods,’ continued he, ‘we should bear with patience; what from our enemies, with manly firmness; and such were the maxims of our forefathers. From unshaken fortitude in misfortune has arisen the present power of this commonwealth, together with that glory which, if our empire, according to the lot of all earthly things, decay, shall still survive to all posterity.’
