Prodicus of Ceos is Born

Prodicus (c. 460-395 BC) was a student of Protagoras and a well-paid sophist, not only by Plato implied to enjoy monetary gain, particularly interested in rhetoric and careful choice of words.

He was very popular, although he charged his students 50 drachmae. Plato has Socrates, who had been to his lectures, joke about this:

Now if I had attended Prodicus's fifty drachma course of lectures, after which, as he himself says, a man has a complete education on this subject, there would be nothing to hinder your learning the truth about the correctness of names at once; but I have heard only the one drachma course, and so I do not know what the truth is about such matters.

Prodicus of Ceos (Greek: Πρόδικος, Pródikos; c. 465-c. 395 BC) was a Greek philosopher, and part of the first generation of Sophists. He came to Athens as ambassador from Ceos, and became known as a speaker and a teacher. Plato treats him with greater respect than the other sophists, and in several of the Platonic dialogues Socrates appears as the friend of Prodicus. Prodicus made linguistics and ethics prominent in his curriculum. The content of one of his speeches is still known, and concerns a fable detailing the education of Heracles by Virtue. He also interpreted religion through the framework of naturalism.
