Plato's PROTAGORAS, Part 5

Most of what we know about the greatest of the Sophists, Protagoras, comes from Plato. Whether, then, what we know about him accurately reflects the reality, we cannot be certain. He was, certainly, one of the most famous itinerant teachers of rhetoric in classical Greece. He is most famous for the line, "Man is the measure of all things," as quoted by Socrates/Plato in the dialogue Theatetus, a dialogue that we hope to read for Simple Gifts at a later date. In this dialogue, the famous but aged rhetorician, encounters Socrates while staying at the home of Callias, a wealthy Athenian. Many other characters are featured or present, including several other prominent Sophists.
