Sweet, David R., "Introduction to the Greater Hippias," The Roots of Political Philosophy: Ten Forgotten Socratic Dialogues, ed. Thomas L. Pangle, Ithaca: Cornell University Press, 1987, 340-55.

Excerpt:

Hippias of Elis was among the half dozen most influential Greek sophists, yet the surviving information about him comes principally from three Platonic dialogues, the Protagoras, the Greater Hippias, and the Lesser Hippias, and from one passage in Xenophon’s Memorabilia. He was evidently a man who considered the aim of life to be self-sufficiency, and to this end he accumulated as many skills as possible. The skill he seems to have prized above all, however, was his ability at speaking.
