Marcus Cornelius Fronto (c. 100 – late 160s AD), best known as Fronto, was a Roman grammarian, rhetorician, and advocate. Of Berber origin, he was born at Cirta (modern-day Constantine, Algeria) in Numidia. He was suffect consul for the nundinium of July–August 142 with Gaius Laberius Priscus as his colleague.[1] Emperor Antoninus Pius appointed him tutor to his adopted sons, the future emperors Marcus Aurelius and Lucius Verus.
