Marcus Cornelius, was chosen for his eloquence to instruct the emperors Marcus Aurelius and Lucius Verus in rhetoric; in recompense of which he was promoted to the consulship, and a statue was erected to his honour. He taught Marcus Aurelius not only eloquence, but the duty of kings, and excellent morals. Some say he wrote against the Christians. A sect was formed of those who looked upon him as a model of perfect eloquence, and those were called Frontoiani. The Civilians, whose names were Fronto, mentioned in the Pandects, were probably descended from him.
