1911 Encyclopædia Britannica/Orbilius, Pupillus

ORBILIUS, PUPILLUS, a Latin grammarian of the 1st century A.D., who had a school at Rome, where the poet Horace was one of his pupils. Horace (Epistles, ii.) criticizes his old schoolmaster and describes him as plagosus (a flogger), and Orbilius has become proverbial as a disciplinarian pedagogue.
