The audience of a travelling sophist was what might be expected among a people who lived very much out of doors. When a stranger appeared who was known by his professional dress, and whose reputation had preceded him, the people clustered round him—like iron filings sticking to a magnet, says Themistius.[161] If there was a resident sophist, the two were pitted together; just as if, in modern times, a famous violinist from Paris or Vienna might be asked to play at the next concert with the leading violinist in London. It was a matter not only of professional honour, but also of obligation. A man could not refuse. There is a story in Plutarch[162] about a sophist named Niger who found himself in a town in Galatia which had a resident professor. The resident made a discourse. Niger had, unfortunately, a fish-bone in his throat and could not easily speak; but he had either to speak or to lose his reputation: he spoke, and an inflammation set in which killed him. There is a much longer story in Philostratus[163] of Alexander Peloplato going to Athens to discourse in a friendly contest with Herodes Atticus. The audience gathered together in a theatre in the Ceramicus, and waited a long time for Herodes to appear: when he did not come, they grew angry and thought that it was a trick, and insisted on Alexander coming forward to discourse before Herodes arrived. And when Herodes did arrive, Alexander suddenly changed his style—sang tenor, so to speak, instead of bass—and Herodes followed him, and there was a charming interchange of compliments: “We sophists,” said Alexander, “are all of us only slices of you, Herodes.” Sometimes they went to show their skill at one of the great festivals, such as that of Olympia. Lucian[164] tells a story of one who had plucked feathers from many orators to make a wonderful discourse about Pythagoras. His object was to gain the glory of delivering it as an extempore oration, and he arranged with a confederate that its subject should be the subject selected for him by the audience. But the imposture was too barefaced: some of the hearers amused themselves by assigning the different passages to their several authors; and the sophist himself at last joined in the universal laughter. And Dio Chrysostom[165] draws a picture of a public place at Corinth during the Isthmian games, which he alleges to be as true of the time of Diogenes as of his own: “You might hear many poor wretches of sophists shouting and abusing one another, and their disciples, as they call them, squabbling, and many writers of books reading their stupid compositions, and many poets singing their poems, and many jugglers exhibiting their marvels, and many soothsayers giving the meaning of prodigies, and ten thousand rhetoricians twisting law-suits, and no small number of traders driving their several trades.”
