Quintilian sees these formative years as the most critical to the education of an orator: “The infancy of the mind is as important as the infancy of the body and needs as much attention” (Quintilian 1.1.1-24). The role of the orator's nurse is greatly emphasized as “it is she that the boy will hear first, it is her words that he will imitate” (Laing, 519). Parents play an equally important role, their education being a determining factor in the orator's progress. Thirdly, the "paedagogus", (the slave who attends the young orator) “must be well educated and ready at all times to correct errors in grammar” (Laing, 520). Finally, Quintilian stresses that the orator should be educated by “the most accomplished teacher” (1.1.22). This ideal teacher is described in detail in (2.2.5).
