“Like other Sophists, he was an itinerant that practiced in various cities and giving public exhibitions of his skill at the great pan-Hellenic centers of Olympia and Delphi, and charged fees for his instruction and performances. A special feature of his displays was to ask miscellaneous questions from the audience and give impromptu replies.”
“Gorgias was born in a colony in eastern Sicily that was an ally of Athens. He had a brother who was a physician, and had sometimes accompanied him during his travels. His sister had a grandson who would go on to dedicate a golden statue to his great uncle at Delphi.”
“Gorgias is said to have studied under Empedocles of Acragas, but it is not known when, where, for how long, or in what capacity. When he was around sixty years old he was sent to Athens by his fellow-citizens as the head of an embassy to ask for Athenian protection against the aggression of the Syracusans. Gorgias’s primary occupation was as a teacher of rhetoric. According to Philostratus, “I understand that he attracted the attention of the most admired men, Critias and Alcibiades, who were young, and Thucydides and Pericles who were already old. Agathon too, the tragic poet, whom Comedy regards as wise and eloquent, often Gorgianizes in his iambic verse.”
“He was reputed to have lived to be one hundred and eight years old.”
“He won admiration for his ability to speak on any subject. He accumulated considerable wealth; enough to commission a gold statue of himself for a public temple. After his Pythian Oration, the Greeks installed a solid gold statue of him in the temple of Apollo at Delphi.”
