Volume 2 of The History of Rome by the Nobel Prize winning classical historian Theodor Mommsen (1817-1903) extends from the unification of Italy to the subjugation of Carthage and the Greek States. This monumental work became the enduring rival of Edward Gibbon's Decline and Fall of the Roman Empire.
