A good teacher was by definition a strict teacher; pedagogical reputations were made by the vigor of the beatings administered. The practice was time-honored and entrenched: as part of his final examination at Cambridge, a graduate in grammar in the late Middle Ages was required to demonstrate his pedagogical fitness by flogging a dull or recalcitrant boy. Learning Latin in this period was, as a modern scholar has put it, a male puberty rite. Even for an exceptionally apt student, that puberty rite could not have been pleasant.
