History of the Peloponnesian War

For the character of the disorder surpassed description; and while in other respects also it attacked every one in a degree more grievous than human nature could endure, in the following way, especially, it proved itself to be something different from any of the diseases familiar to man. All the birds and beasts that prey on human bodies, either did not come near them, though there were many lying unburied, or died after they had tasted them.

As a proof of this, there was a marked disappearance of birds of this kind, and they were not seen either engaged in this way, or in any other; while the dogs, from their domestic habits, more clearly afforded opportunity of marking the result I have mentioned.
