Peter Kalkavage is a member of the senior faculty at St. John's College in Annapolis, Maryland, where he has taught for thirty years. He is the author of numerous articles on philosophy. He translated Plato's Timaeus and co-translated Plato's Phaedo and Sophist.

"Kalkavage's translation and commentary provide invaluable assistance to students of Plato's Timaeus. The translation is accurate, but readable. And Kalkavage packs a great deal of relevant historical, musical, and mathematical information into his notes." —Catherine Zuckert, Nancy Reeves Dreux Professor of Political Science, University of Notre Dame
