Sententiae Antiquae writes about lycanthropy and Pliny the Elder. “But it Italy they also believe that the gaze of a wolf is harmful—specifically that it will take the voice from any man they see first. Africa and Egypt have wolves that are slow and small, while the colder climates produce fierce and wild animals. We ought to believe with certainty that accounts of men turning into wolves and then back to themselves again are false; or we should be prepared  to believe all the tales that are fantastic from as many generations.” (Thanks, Tim!)
