Lucius Annaeus Seneca (often known simply as Seneca; ca. 4 BC – AD 65) was a Roman Stoic philosopher, statesman, dramatist, and in one work humorist, of the Silver Age of Latin literature. He was tutor and later advisor to emperor Nero. While he was later forced to commit suicide for alleged complicity in the Pisonian conspiracy to assassinate Nero, the last of the Julio-Claudian emperors, he may have been innocent. His father was Seneca the Elder and his elder brother was Gallio.

Lucius Annaeus Seneca was born in Cordoba, in the Baetica, the southern highly romanized province of Spain. One of his revisionist modern biographers, however, Miriam Griffin says in her biography of Seneca that "the evidence for Seneca's life before his exile in 41 is so slight, and the potential interest of these years, for social history as well as for biography, is so great that few writers on Seneca have resisted the temptation to eke out knowledge with imagination." Griffin also states, apparently inferring from ancient sources, that Seneca was born in either 8, 4, or 1 BC. She thinks he was born between 4 and 1 BC and was a resident in Rome by AD 5. Seneca says that he was carried to Rome in the arms of his mother's stepsister. Griffin says that, allowing for rhetorical exaggeration, means "it is fair to conclude that Seneca was in Rome as a very small boy." Be that as it may, it is clear that he was in Rome at a relatively early stage in his life.
