his fallen rival, and banished him to Thessalonica, where he was soon afterward assassinated in some mysterious manner, it being to this day uncertain whether he perished by the order of the senate, by a tumult of the soldiers, or by the machinations of Constantine. But it is certain that the "first Christian emperor" regarded the fact that a man might stand in the way of his ambition, or possibly compromise his safety, as a sufficient reason for putting him to death, even if the unlucky person happened to be his own son. "Thus the mighty and victorious Constantine," saith Eusebius, "adorned with every virtue of religion, with his most pious son, Crispus Cæsar, resembling in all things his father, recovered the East as his own, and thus restored the Roman Empire to its ancient state of one united body; extending their peaceful sway around the world, from the rising sun to the opposite regions, to the north and the south, even to the borders of the declining day." But this greatest statesman, politician, and ruler--this absolute, untroubled, and self-confident atheist--had only "the godliness that is profitable for the life that now is"; for this "Christian" had never been baptized (knowing that an emperor can not be a Christian); and he afterward murdered in cold blood, without provocation, "his most pious son, Crispus Cæsar, resembling in all things his father"; his own wife Fausta, and the youthful Licinius, son of his sister Constantia; just as he systematically assassinated every one whom his calm, merciless, wise policy thought to be possibly inimical to his own safety. But he realized the life-long ambition of his soul, the restoration of the unity of the Roman Empire under his own authority; and did it by the aid of the Christian Church, which he bribed, corrupted, and secularized, until it acknowledged him to be king instead of Jesus Christ. These historical details, however, anticipate our narrative of Arius the Libyan, to which we must now return. CHAPTER II. A NAVAL QUESTION. After the overthrow of the Christian communities which Ulfilas had founded among the Goths, Constantine called Eusebius, Bishop of Cæsarea, unto himself, and began to make diligent inquiries concerning the churches of Syria and of Egypt; and, having obtained all of the information current among the bishops, he entered into conversation with Eusebius, apparently for the purpose of still further satisfying himself upon certain points involved in his investigations. "Thou sayest," said Constantine, "that, in spite of the persecution in which many bishops and private persons have suffered martyrdom, the Church constantly increases in numbers and influence."
