Spectrum of topics Nonetheless, very few fragments from Protagoras have survived, although he is known to have written several different works: Antilogiae and Truth. The latter is cited by Plato, and was known alternatively as, The Throws (a wrestling term referring to the attempt to floor an opponent). It began with the "Man is the measure" (ἄνθρωπος μέτρον) pronouncement. According to Diogenes Laërtius other books by Protagoras include: On the Gods, Art of Eristics, Imperative, On Ambition, On Incorrect Human Actions, On Those in Hades, On Sciences, On Virtues, On the Original State of Things and Trial over a Fee.
