History of the Peloponnesian War

On the city of Athens it fell suddenly, and first attacked the men in the Piraeus; so that it was even reported by them that the Peloponnesians had thrown poison into the cisterns; for as yet there were no fountains there. Afterwards it reached the upper city also; and then they died much more generally. Now let every one, whether physician or unprofessional man, speak on the subject according to his views;
