Lamia

“Once upon a time, so runs the story, there was a dangerous and savage species of animal whose main haunt was in the uninhabited regions of Libya. For that country even to this day seems to produce all sorts of living creatures, reptiles as well as other kinds. Now among them was the species with which this story has to deal. It had a body that, in general, was a composite thing of the most incongruous parts, an utter monstrosity, and it used to roam as far as the Mediterranean and the Syrtis in search of food. For it hunted both the beasts of prey such as the lion and the panther, even as those hunt the deer and the wild asses and the sheep, but took the most delight in catching men.”

—Dio Chrysostom: the Lamia
