History of the Peloponnesian War

The following winter the plague a second time attacked the Athenians, having indeed never entirely left them, though there had been some abatement of it.

It lasted the second time not less than a year—the former attack having lasted two—so that nothing reduced the power of the Athenians more than this.

For not less than four thousand four hundred heavy-armed in the ranks died of it, and three hundred of the equestrian order, with a number of the multitude that was never ascertained.

It was at that time also that the Numerous earthquakes happened at Athens, Euboea, and Boeotia, particularly at Orchomenos in the last-named country.
