Marcus Fabius Quintilianus (Latin: [kᶣiːn.tɪ.li.ˈaː.nʊs]; c. 35 – c. 100 AD) was a Roman educator and rhetorician born in Hispania, widely referred to in medieval schools of rhetoric and in Renaissance writing. In English translation, he is usually referred to as Quintilian , although the alternate spellings of Quintillian and Quinctilian are occasionally seen, the latter in older texts.
