Tacitus was the greatest historian of the Roman empire. Born in about AD 55, he served as administrator and leading senator. This career gave him an intimate view of the empire at its highest levels, experience brought to bear on his writing. His major works are the Annals and the Histories, both of which have come down to us incomplete. Between them, they cover a period of about 80 years, from the death of the first emperor, Augustus, to the death of Domitian in 96AD. In addition, Tacitus also composed two short historical books or essays, the Agricola (about his father-in-law, a distinguished provincial governor) and the Germania, an account of the tribes beyond the Rhine.
