The departure of Alaric and the death of Gainas freed the Eastern Romans from the double danger that has impended over them. They were neither to see an independent German kingdom on the Danube and Morava, nor to remain under the rule of a semi-civilized German _Magister militum_, making and unmaking ministers, and perhaps Cæsars, at his good pleasure. The weak Arcadius was enabled to spend the remaining seven years of his life in comparative peace and quiet. His court was only troubled by an open war between his spouse, the Empress Ælia Eudoxia, and John Chrysostom, the Patriarch of Constantinople. John was a man of saintly life and apostolic fervour, but rash and inconsiderate alike in speech and action. His charity and eloquence made him the idol of the populace of the imperial city, but his austere manners and autocratic methods of dealing with his subordinates had made him many foes among the clergy. The patriarch’s enemies were secretly supported by the empress, who had taken offence at the outspoken way in which John habitually denounced the luxury and insolence of her court. She favoured the intrigues of Theophilus, Patriarch of Alexandria, against his brother prelate, backed the Asiatic clergy in their complaints about John’s oppression of them, and at last induced the Emperor to allow the saintly patriarch to be deposed by a hastily-summoned council, the “Synod of the Oak” held outside the city. The populace rose at once to defend their pastor; riots broke out, Theodosius was chased back to Egypt, and the Emperor, terrified by an earthquake which seemed to manifest the wrath of heaven, restored John to his place. Next year, however, the war between the empress and the patriarch broke out again. John took the occasion of the erection of a statue of Eudoxia in the Augustaeum to recommence his polemics. Some obsolete semi-pagan ceremonies at its dedication roused his wrath, and he delivered a scathing sermon in which—if his enemies are to be believed—he compared the empress to Herodias, and himself to John the Baptist. The Emperor, at his wife’s demand, summoned another council, which condemned Chrysostom, and on Easter Day, A.D. 404, seized the patriarch in his cathedral by armed force, and banished him to Asia. That night a fire, probably kindled by the angry adherents of Chrysostom, broke out in St. Sophia, which was burnt to the ground. From thence it spread to the neighbouring buildings, and finally to the Senate-house, which was consumed with all the treasures of ancient Greek art of which Constantine had made it the repository.
