Towards the winter Pericles delivered, from a lofty platform erected in the Ceramicus, the funeral oration of those who had fallen in the war. This speech, or at all events the substance of it, has been preserved by Thucydides, who may possibly have heard it pronounced. It is a valuable monument of eloquence and patriotism, and particularly interesting for the sketch which it contains of Athenian manners as well as of the Athenian constitution. In the following year (B.C. 430) the Peloponnesians, under Archidamus, renewed their invasion of Attica. At the same time the Athenians were attacked by a more insidious and a more formidable enemy. The plague broke out in the crowded city. This terrible disorder, which was supposed to have originated in AEthiopia, had already desolated Asia and many of the countries around the Mediterranean. A great proportion of those who were seized perished in from seven to nine days. It frequently attacked the mental faculties, and left even those who recovered from it so entirely deprived of memory that they could recognise neither themselves nor others. The disorder being new, the physicians could find no remedy in the resources of their art. Despair now began to take possession of the Athenians. Some suspected that the Peloponnesians had poisoned the wells; others attributed the pestilence to the anger of Apollo. A dreadful state of moral dissolution followed. The sick were seized with unconquerable despondency; whilst a great part of the population who had hitherto escaped the disorder, expecting soon to be attacked in turn, abandoned themselves to all manner of excess, debauchery, and crime. The numbers carried off by the pestilence can hardly be estimated at less than a fourth of the whole population.
