Antiphon (person)
Antiphon the Sophist lived in Athens probably in the last two decades of the 5th century BC. There is an ongoing controversy over whether he is one and the same with Antiphon (Ἀντιφῶν) of the Athenian deme Rhamnus in Attica (480–411 BC), the earliest of the ten Attic orators. For the purposes of this article, they will be treated as distinct persons.
