Antiphon of Rhamnus (/ˈæntɪfɒn, -ən/; Ancient Greek: Ἀντιφῶν ὁ Ῥαμνούσιος; 480–411 BC) was the earliest of the ten Attic orators, and an important figure in fifth-century Athenian political and intellectual life.
He was active in political affairs in Athens, and, as a zealous supporter of the oligarchical party, was largely responsible for the establishment of the Four Hundred in 411 (see Theramenes); upon restoration of the democracy shortly afterwards, he was accused of treason and condemned to death.
[1] Thucydides famously characterized Antiphon's skills, influence, and reputation: ...He who concerted the whole affair [of the 411 coup], and prepared the way for the catastrophe, and who had given the greatest thought to the matter, was Antiphon, one of the best men of his day in Athens; who, with a head to contrive measures and a tongue to recommend them, did not willingly come forward in the assembly or upon any public scene, being ill-looked upon by the multitude owing to his reputation for cleverness; and who yet was the one man best able to aid in the courts, or before the assembly, the suitors who required his opinion.
Indeed, when he was afterwards himself tried for his life on the charge of having been concerned in setting up this very government, when the Four Hundred were overthrown and hardly dealt with by the commons, he made what would seem to be the best defence of any known up to my time.Antiphon may be regarded as the founder of political oratory, but he never addressed the people himself except on the occasion of his trial.
Fragments of his speech then, delivered in defense of his policy (called Περὶ μεταστάσεως) have been edited by J. Nicole (1907) from an Egyptian papyrus.
