and that between Octavius and Antony. The wars of Caesar inaugurated the imperial régime when the Empire was young and in full vigor, and when military discipline was carried to perfection; those of Constantine were in the latter days of the Empire, when it was impossible to reanimate it, and all things were tending rapidly to dissolution,--an exceedingly gloomy period, when there were neither statesmen nor philosophers nor poets nor men of genius, of historic fame, outside the Church. Therefore I shall not dwell on these uninteresting wars, brought about by the ambition of six different emperors, all of whom were aiming for undivided sovereignty. There were in the West Maximian, the old colleague of Diocletian, who had resigned with him, but who had reassumed the purple; his son, Maxentius, elevated by the Roman Senate and the Praetorian Guard,--a dissolute and imbecile young man, who reigned over Italy; and Constantine, who possessed Gaul and Britain. In the East were Galerius, who had married the daughter of Diocletian, and who was a general of considerable ability; Licinius, who had the province of Illyricum; and Maximin, who reigned over Syria and Egypt. The first of these emperors who was disposed of was Maximian, the father of Maxentius and father-in-law of Constantine. He was regarded as a usurper, and on the capture of Marseilles, he under pressure of Constantine committed suicide by strangulation, A.D. 310. Galerius did not long survive, being afflicted with a loathsome disease, the result of intemperance and gluttony, and died in his palace in Nicomedia, in Bithynia, the capital of the Eastern provinces. The next emperor who fell was Maxentius, after a desperate struggle in Italy with Constantine,--whose passage over the Alps, and successive victories at Susa (at the foot of Mont Cenis, on the plains of Turin), at Verona, and Saxa Rubra, nine miles from Rome, from which Maxentius fled, only to perish in the Tiber, remind us of the campaigns of Hannibal and Napoleon. The triumphal arch which the victor erected at Rome to commemorate his victories still remains as a monument of the decline of Art in the fourth century. As a result of the conquest over Maxentius, the Praetorian guards were finally abolished, which gave a fatal blow to the Senate, and left the capital disarmed and exposed to future insults and dangers.
