Originally published in 1924, this book contains the Latin text of the first book of Quintillian's Institutionis Oratoriae. Quintillian's work on oratorical principles was much respected during the revival of Classical learning in the Renaissance, but largely forgotten subsequently. Colson supplies a detailed exegetical commentary, as well as a thorough history of the composition of Quintillian's work and its transmission through the ages. This book will be of value to anyone with an interest in ancient oratory or in this long-neglected text.
