Edward Gibbon, an English historian, published The History of the Decline and Fall of the Roman Empire in six volumes between 1776 and 1788. This is Chapter 18 of that work. He follows Rome from the prosperous age of Trajan and the Antonines, around the year 100, through the fall of the West and on to the Ottoman capture of Constantinople in 1453.

Chapter 18 takes up character of Constantine—Gothic War—Death of Constantine—Division of the empire among his three sons—Persian War—Tragic deaths of Constantine the Younger and Constans—Usurpation of Magnentius—Civil war—Victory of Constantius. The footnotes are not in this reading; what you have is the narrative.
