Who was Orbilius, and how did he influence Horace’s early education?

Orbilius was a famous schoolmaster of Sabellian origin who taught in Rome. Horace’s father, who was a freedman, personally ensured his son received the best available education by enrolling him in Orbilius’s school.1

According to Horace, Orbilius was a firm believer in the use of corporal punishment as a teaching method. This early educational experience is one of the few specific details known about Horace's formative years before he later traveled to Athens to attend lectures at the Academy.1
