The dates of the birth and death of Tacitus are uncertain, but it is probable that he was born about 54 A. D. and died after 117. He was a contemporary and friend of the younger Pliny, who addressed to him some of his most famous epistles. Tacitus was apparently of the equestrian class, was an advocate by training, and had a reputation as an orator, though none of his speeches has survived. He held a number of important public offices, and married the daughter of Agricola, the conqueror of Britain, whose life he wrote.
