Cicero's letters to friends span the period from 62 BC, when his political career was at its peak, to 43 BC, when he was put to death by the victorious Triumvirs.

Cicero was a prodigious letter writer, and happily a splendid treasury of his letters has come down to us: collected and in part published not long after his death, over 800 of them were rediscovered by Petrarch and other humanists in the fourteenth century. Among classical texts this correspondence is unparalleled; nowhere else do we get such an intimate look at the life of a prominent Roman and his social world, or such a vivid sense of a momentous period in Roman history.
