The reign of Constantine as sole emperor was marked by another event, A.D. 325. which had a great influence on the subsequent condition of the world in a moral and religious point of view, and this was the famous [pg 625] Council of Nicæa, which assembled to settle points of faith and discipline in the new religion which was now established throughout the empire. It is called the first Ecumenical, or General Council, and was attended by three hundred and eighteen bishops, with double the number of presbyters, assembled from all parts of the Christian world. Here the church and the empire met face to face. In this council the emperor left the cares of State, and the command of armies, to preside over discussions on the doctrine of the Trinity, as expounded by two great rival parties,—one headed by Athanasius, then archdeacon, afterward archbishop of Alexandria—the greatest theologian that had as yet appeared in the church,—and the other by Arius, a simple presbyter of Alexandria, but a man of subtle and commanding intellect. Arius maintained that the Son, the second person of the Trinity, derived his being from the Father within the limits of time, and was secondary to him in power and glory. Athanasius maintained that the Son was co-eternal with the Father, and the same in substance with the Father. This theological question had long been discussed, and the church was divided between the two parties, each of which exhibited extreme acrimony. Constantine leaned to the orthodox side, although his most influential adviser, Eusebius, bishop of Cæsarea, the historian, inclined to the Arian view. But the emperor was more desirous to secure peace and unity, than the ascendency of any dogma, and the doctrine of Athanasius became the standard of faith, and has since remained the creed of the church.
Assassination of Crispus. The new capital.
After the settlement of the faith of the church, now becoming the great power of the world, the reign of Constantine was disgraced by a domestic tragedy seldom paralleled in history. His son, Crispus, by a low-born woman, conspicuous for talents and virtues, either inflamed the jealousy of his father, or provoked him by a secret conspiracy. It has never been satisfactorily settled whether he was a rival or a conspirator, but he was accused, [pg 626] tried, and put to death, in the twentieth year of the reign, while Constantine was celebrating at Rome the festival of his vicennalia. After this bloody tragedy, for which he is generally reproached, he took his final departure from Rome, and four years after, the old capital was degraded to the rank of a secondary city, and Constantinople was dedicated as the new capitol of the empire. From the eastern promontory to the Golden Horn, the extreme length of Constantinople was three Roman miles, and the circumference measured ten, inclosing an area of two thousand acres, besides the suburbs. The new city was divided into fourteen wards, and was ornamented with palaces, fora, and churches. The church of St. Sophia was built on the site of an old temple, and was in the form of a Greek cross, surmounted by a beautiful and lofty dome. In a century afterward, Constantinople rivaled Rome in magnificence. It had a capitol, a circus, two theatres, eight public baths, fifty-two porticoes, eight aqueducts, four halls, and fourteen churches, and four thousand three hundred and eighty-three large palatial residences.
New divisions of the empire.
After the building of this new and beautiful city, Constantine devoted himself to the internal regulation of the empire, which he divided into four prefectures, subdivided into thirteen dioceses, each governed by vicars or vice-prefects, who were styled counts and dukes. The provinces were subdivided to the number of one hundred and sixteen. Three of these were governed by proconsuls, thirty-seven by consuls, five by correctors, and seventy-one by presidents, chosen from the legal profession, and called clarissimi. The prefecture of the East embraced the Asiatic provinces, together with Egypt, Thrace, and the lower Mœsia; that of Illyricum contained the countries between the Danube, the Ægean, and the Adriatic; that of Italy extended over the Alps to the Danube; and that of the Gauls embraced the western provinces beyond the Rhine and the Alps.
Changes in the army.
The military power was separated from the civil. There [pg 627] were two master-generals, one of infantry, and the other of cavalry, afterward increased to eight, under whom were thirty-five commanders, ten of whom were counts, and twenty dukes. The legions were reduced from six thousand to fifteen hundred men. Their number was one hundred and thirty-two, and the complete force of the empire was six hundred and forty-five thousand, holding five hundred and eighty-three permanent stations.
The ministers.
The ministers of the palace, who exercised different functions about the presence of the emperor, were seven in number: the prefect of the bed-chamber; a eunuch, who waited on the emperor; the master of offices—the supreme magistrate of the palace; the quæstor—at the head of the judicial administration, and who composed the orations and edicts of the emperor; the treasurer, and two counts of domestics, who commanded the body-guard.
