Lucius Annaeus Seneca, statesman, philosopher, advocate and man of letters, was born in Spain around 4BC. He rose to prominence at Rome, pursuing a double career in the courts and political life, until Claudius sent him into exile exile on the island of Corsica for eight years. Recalled in AD49, he was appointed tutor to the boy who was to become, in AD54, the emperor Nero. Seneca acted for eight years as Nero's unofficial chief minister until Nero too turned against him and he retired from public life to devote himself to philosophy and writing. In AD65, following the discovery of a plot against the emperor, he and many others were compelled by Nero to commit suicide. C.D.N. Costa has spent most of his working life at Birmingham University, where he is Professor of Classics and Chairman of the School of Antiquity. Among other works, he has written commentaries on the works of Seneca, Letters, Dialogues and the tragedy Medea.
