Genethlius (el|Γενέθλιος|Genéthlios) was a 3rd-century Arab sophist from Petra, Arabia Petraea. His father was also named Genethlius.[1]
He was a pupil of the Greek sophists Minucianus (grc|Μινουκιανός) and Agapetus (grc|Ἀγαπητός), and then he himself became a teacher and practiced rhetoric in Athens. He has been known as a rival to the famous Callinicus of Petra.[2] [3]
Genethlius is also thought by some scholars to be the author of the first treatise in the corpus of Menander Rhetor.
