M. Cornelius Fronto was a Roman senator from North Africa, and the foremost Latin orator and legal advocate of the mid-second century A.D. Fronto's talent and fame led to his appointment as tutor to Marcus Aurelius and Lucius Verus, the adoptive sons of the emperor Antoninus Pius, in the late 130s A.D. Fronto's extant correspondence, discovered in the early nineteenth century, consists of around two hundred letters extending over a period of more than twenty-five years, from the late 130s to the mid-160s A.D. In this period, Fronto educated Marcus and Verus in the art of Latin rhetoric, and watched with pride as his illustrious pupils matured and ascended the throne. The correspondence includes letters Fronto exchanged with Marcus and Verus, their father Antoninus Pius, leading senators, and other influential figures at court. This collection features new English translations and commentaries on fifty-four letters from Fronto's correspondence. The letters have been selected for the insights they provide into the political and social history of the Roman empire in the second century A.D., with particular emphasis on court politics and intrigue, the Parthian War, and family relationships among members of the Roman elite. The letters have been arranged in approximate chronological order, enabling the reader to take a journey through Fronto's life over a quarter of a century. The introduction discusses Fronto's life and career, Roman letter writing, the history and character of Fronto's correspondence, and the relationship between Fronto and Marcus Aurelius.
