History of the Peloponnesian War

It invaded Athens on a sudden and touched first upon those that dwelt in Piraeus, insomuch as they reported that the Peloponnesians had cast poison into their wells (for springs there were not any in that place). But afterwards it came up into the high city, and then they died a great deal faster.

Now let every man, physician or other, concerning the ground of this sickness, whence it sprung, and what causes he thinks able to produce so great an alteration, speak according to his own knowledge. For my own part, I will deliver but the manner of it and lay open only such things as one may take his mark by to discover the same if it come again, having been both sick of it myself and seen others sick of the same.

This year, by confession of all men, was of all other, for other diseases, most free and healthful. If any man were sick before, his disease turned to this;

if not, yet suddenly, without any apparent cause preceding and being in perfect health, they were taken first with an extreme ache in their heads, redness and inflammation of the eyes; and then inwardly, their throats and tongues grew presently bloody and their breath noisome and unsavoury.

Upon this followed a sneezing and hoarseness, and not long after the pain, together with a mighty cough, came down into the breast. And when once it was settled in the stomach, it caused vomit; and with great torment came up all manner of bilious purgation that physicians ever named.

Most of them had also the hickyexe which brought with it a strong convulsion, and in some ceased quickly but in others was long before it gave over.
