A celebrated Greek historian; born at Megalopolis in Arcadia, 210 B. C., while much of Greece was still independent; died 127, after it had long been a province of Rome, and himself an admired companion of its conquerors. His work, "Histories", comprised 40 books, of which only the first five have come down to us complete: it was the author's purpose to write the history of "all the known regions of the civilized world which had fallen under the sway of Rome".
