The works of his which survive are these:
* * The Art of Controversy. Of Wrestling. On Mathematics. Of the State. Of Ambition. Of Virtues. Of the Ancient Order of Things. On the Dwellers in Hades. Of the Misdeeds of Mankind. A Book of Precepts. Of Forensic Speech for a Fee, two books of opposing arguments. This is the list of his works.[*](That the list is defective is evident from the fact that the two works by which Protagoras is best known (supra, §§ 51, 54) are not here named.) Moreover there is a dialogue which Plato wrote upon him. V2_469
Philochorus says that, when he was on a voyage to Sicily, his ship went down, and that Euripides hints at this in his Ixion.
