Lucius Annaeus Seneca the Elder, also known as Seneca the Rhetorician, was a Roman writer, born of a wealthy equestrian family of Corduba, Hispania. He wrote a collection of reminiscences about the Roman schools of rhetoric, six books of which are extant in a more or less complete state and five others in epitome only. His principal work, a history of Roman affairs from the beginning of the Civil Wars until the last years of his life, is almost entirely lost to posterity. Seneca lived through the reigns of three significant emperors; Augustus, Tiberius and Caligula. He was the father of Lucius Junius Gallio Annaeanus, best known as a Proconsul of Achaia; his second son was the dramatist and Stoic philosopher Seneca the Younger (Lucius), who was tutor of Nero, and his third son, Marcus Annaeus Mela, became the father of the poet Lucan.
