"M. Fabi Quintiliani institutionis oratoriae liber decimus" by Quintilian is Book X of a twelve-volume textbook on rhetoric published around 95 AD. Written during Emperor Domitian's oppressive reign, when political oratory had died and corruption flourished, Quintilian's work attempted to revive earlier ideals of oratorical education. Lost for centuries, a complete manuscript was dramatically discovered in a Swiss monastery dungeon in 1416, igniting fervent excitement among Renaissance humanists who had only known fragments for six hundred years.
