In the Greco-Roman world, the grammarian was responsible for the second stage in the traditional education system, after a boy had learned his basic letters. The job of the grammarian was to teach the ancient poets such as Homer and Virgil, and the correct way of speaking before a boy moved on to the study of rhetoric under the rhetor. Despite often humble origins, some grammarians went on to achieve elevated positions in Rome, though few enjoyed financial success.
Some grammarians achieved elevated positions in the Roman world and enjoyed preferential treatment, despite their relatively lowly job and often humble origins. They were exempt from local taxes in Rome for instance. By tutoring the children of the wealthy, grammarians could meet and become associated with prominent families in Rome. Marcus Antonius Gnipho was part of the household of Julius Caesar. This despite the fact that some noted grammarians had originally been brought to Rome as captives. Twelve of the twenty grammarians described by Suetonius in De Illustribus Grammaticis had been slaves.
Latin grammarians, like their Greek equivalents, came from all over the Roman Empire, including Syria, Spain, Gaul, Athens and Italy.
