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. Emperor Antoninus Pius appointed him tutor to his adopted sons, the future emperors Marcus Aurelius and Lucius Verus. Source: Wikipedia (en)
