Nor was this the only form of lawless extravagance which owed its origin to the plague. Men now coolly ventured on what they had formerly done in a corner, and not just as they pleased, seeing the rapid transitions produced by persons in prosperity suddenly dying and those who before had nothing succeeding to their property. So they resolved to spend quickly and enjoy themselves, regarding their lives and riches as alike things of a day. Perseverance in what men called honour was popular with none, it was so uncertain whether they would be spared to attain the object; but it was settled that present enjoyment, and all that contributed to it, was both honourable and useful. Fear of gods or law of man there was none to restrain them. As for the first, they judged it to be just the same whether they worshipped them or not, as they saw all alike perishing; and for the last, no one expected to live to be brought to trial for his offences, but each felt that a far severer sentence had been already passed upon them all and hung ever over their heads, and before this fell it was only reasonable to enjoy life a little.
Such was the nature of the calamity, and heavily did it weigh on the Athenians; death raging within the city and devastation without. Among other things which they remembered in their distress was, very naturally, the following verse which the old men said had long ago been uttered:
A Dorian war shall come and with it death. So a dispute arose as to whether dearth and not death had not been the word in the verse; but at the present juncture, it was of course decided in favour of the latter; for the people made their recollection fit in with their sufferings. I fancy, however, that if another Dorian war should ever afterwards come upon us, and a dearth should happen to accompany it, the verse will probably be read accordingly. The oracle also which had been given to the Lacedaemonians was now remembered by those who knew of it. When the god was asked whether they should go to war, he answered that if they put their might into it, victory would be theirs, and that he would himself be with them. With this oracle events were supposed to tally. For the plague broke out as soon as the Peloponnesians invaded Attica, and never entering Peloponnese (not at least to an extent worth noticing), committed its worst ravages at Athens, and next to Athens, at the most populous of the other towns. Such was the history of the plague.
