It is generally agreed that the Protagoras recounts a single meeting which took place in the late 430s. If this is correct, then, as has long been recognized, the dialogue contains a number of disturbing anachronisms. It is the purpose of this study to question the supposition of a single dramatic date. I argue that Plato did not record the events of a single meeting in the dialogue, but that he drew upon the action and dialogue of more than one (...) meeting in the course of Protagoras' visits to Athens. If it can be shown that this is the way in which Plato composed the dialogue, then he is not guilty of the glaring anachronisms in the Protagoras with which he is charged. At the end of this study I suggest a reason for Plato's choice of this method of composition. First, however, the evidence for Protagoras' visits to Athens should be considered. (shrink)

Recent accounts of the life of Protagoras differ widely from one another in their treatment of the ancient sources, and in the conclusions which they draw from them. A re-examination of the evidence, undertaken in 1949–50 as part of a study of the Prometheus trilogy, has convinced me that a new discussion is urgently needed if we are to place the earlier stages of the sophistic movement in the right context historically; and the purpose of this paper is to lay (...) at least a part of the foundation for such a discussion. Since the evidence for the life of Protagoras includes some allusions to his relations with Democritus, and there are some obvious affinities between the careers of Protagoras and Anaxagoras, I have added a short account of the relevant points in the biography of Democritus and a more detailed study of the evidence for the life of Anaxagoras.
