Sources : Lamia

Thomas of Cantimpré [circa 1200-1272 CE] (Liber de natura rerum, Quadrupeds 4.56): The lamia, as he says [i.e. Liber rerum], is a great and most cruel animal. At night it comes out of the forest and enters the forest and breaks the trees and breaks their branches, and this with strong arms too capable for every acre. But when men come up to stop it, it fights with them and bites them. And this in its bite is exceedingly wonderful, as Aristotle relates: a man wounded by the teeth of a lamia is not cured of the bite, until he hears the roaring voice of the beast. - [Badke translation/paraphrase]
