Three famous sophists are referred to together in the Apology of Sokrates as still practising their enviably lucrative itinerant profession in 399 B.C. (not, by implication, in Athens): Gorgias of Leontinoi, Prodikos of Keos and Hippias of Elis. The last of these was the least well known to the Athenian demos, having practised mainly in Dorian cities. There is no extant reference to him in Old Comedy, but we can assume that he was sufficiently famous - especially for his fees (...) (possibly the highest charged by any sophist) - to justify his inclusion as the third of this 'triad'; cf. the triad Protagoras - Hippias - Prodikos in the Protagoras, considered further below. Gorgias was by now a grand old man of about ninety (with more than a decade of active life still ahead of him), the last survivor of the first generation of fee-taking educators, associated first and foremost in the popular mind with the suspect arts of political and forensic persuasion. Prodikos and Hippias were probably in their sixties. (shrink)
