History of the Peloponnesian War

And the body was not wasted while the disease was at its height, but resisted surprisingly the ravages of the disease, so that when the patients died, as most of them did on the seventh or ninth day from the internal heat, they still had some strength left; or, if they passed the crisis, the disease went down into the bowels, producing there a violent ulceration, and at the same time an acute diarrhoea set in, so that in this later stage most of them perished through weakness caused by it.

For the malady, starting from the head where it was first seated, passed down until it spread through the whole body, and if one got over the worst, it seized upon the extremities at least and left its marks there;

for it attacked the privates and fingers and toes, and many escaped with the loss of these, though some lost their eyes also. In some cases the sufferer was attacked immediately after recovery by loss of memory, which extended to every object alike, so that they failed to recognize either themselves or their friends.

Indeed the character of the disease proved such that it baffles description, the violence of the attack being in each case too great for human nature to endure, while in one way in particular it showed plainly that it was different from any of the familiar diseases: the birds, namely, and the fourfooted animals, which usually feed upon human bodies either would not now come near them, though many lay unburied, or died if they tasted of them.
