Description of Greece: Werewolf Myth

Λυκάων δὲ ὁ Πελασγοῦ τοσάδε εὗρεν ἢ ὁ πατήρ οἱ σοφώτερα: Λυκόσουράν τε γὰρ πόλιν ᾤκισεν ἐν τῷ ὄρει τῷ Λυκαίῳ καὶ Δία ὠνόμασε Λυκαῖον καὶ ἀγῶνα ἔθηκε Λύκαια. οὐκέτι δὲ τὰ παρ᾽ Ἀθηναίοις Παναθήναια τεθῆναι πρότερα ἀποφαίνομαι: τούτῳ γὰρ τῷ ἀγῶνι Ἀθήναια ὄνομα ἦν, Παναθήναια δὲ κληθῆναί φασιν ἐπὶ Θησέως, ὅτι ὑπὸ Ἀθηναίων ἐτέθη συνειλεγμένων ἐς μίαν ἁπάντων πόλιν.

[8.2.6] All through the ages, many events that have occurred in the past, and even some that occur to-day, have been generally discredited because of the lies built up on a foundation of fact. It is said, for instance, that ever since the time of Lycaon a man has changed into a wolf at the sacrifice to Lykaion Zeus, but that the change is not for life; if, when he is a wolf, he abstains from human flesh, after nine years he becomes a man again, but if he tastes human flesh he remains a beast for ever.
