Ancus Martius in Roman Biography

An'cus Martius or Marcius, (mar'she-us,) the fourth king of Rome, a grandson of Numa Pompilius, succeeded Tullus Hostilius about 634 B.C. He is considered the lawgiver or founder of the plebeian order, which seems to have received in his reign a distinct political existence. He waged war with success against the Latins, founded Ostia, and built the Pons Sublicius, (Bridge of Piles.) He died about 610, and was succeeded by Tatquinius Priscus. See Niebuhr, "Roman History."
