Appian

Appian, an Alexandrian Greek, who wrote in his own language a valuable history of Rome. It is comprised in 24 books, which follow no chronological order, but deal with the history of each nation conquered by Rome until its conquest, and of the Roman civil wars which preceded the downfall of the Republic; and sum up the statements of earlier authors whose works are lost. He was contemporary with Trajan, Adrian, and Antoninus Pius, the latter of whom made him procurator of the empire.
