But Rufinus soon experienced, that a prudent minister should constantly secure his royal captive by the strong, though invisible chain of habit; and that the merit, and much more easily the favor, of the absent, are obliterated in a short time from the mind of a weak and capricious sovereign. While the præfect satiated his revenge at Antioch, a secret conspiracy of the favorite eunuchs, directed by the great chamberlain Eutropius, undermined his power in the palace of Constantinople. They discovered that Arcadius was not inclined to love the daughter of Rufinus, who had been chosen, without his consent, for his bride; and they contrived to substitute in her place the fair Eudoxia, the daughter of Bauto, a general of the Franks in the service of Rome; and who was educated, since the death of her father, in the family of the sons of Promotus. The young emperor, whose chastity had been strictly guarded by the pious care of his tutor Arsenius, eagerly listened to the artful and flattering descriptions of the charms of Eudoxia: he gazed with impatient ardor on her picture, and he understood the necessity of concealing his amorous designs from the knowledge of a minister who was so deeply interested to oppose the consummation of his happiness. Soon after the return of Rufinus, the approaching ceremony of the royal nuptials was announced to the people of Constantinople, who prepared to celebrate, with false and hollow acclamations, the fortune of his daughter. A splendid train of eunuchs and officers issued, in hymeneal pomp, from the gates of the palace; bearing aloft the diadem, the robes, and the inestimable ornaments, of the future empress. The solemn procession passed through the streets of the city, which were adorned with garlands, and filled with spectators; but when it reached the house of the sons of Promotus, the principal eunuch respectfully entered the mansion, invested the fair Eudoxia with the Imperial robes, and conducted her in triumph to the palace and bed of Arcadius. The secrecy and success with which this conspiracy against Rufinus had been conducted, imprinted a mark of indelible ridicule on the character of a minister, who had suffered himself to be deceived, in a post where the arts of deceit and dissimulation constitute the most distinguished merit. He considered, with a mixture of indignation and fear, the victory of an aspiring eunuch, who had secretly captivated the favor of his sovereign; and the disgrace of his daughter, whose interest was inseparably connected with his own, wounded the tenderness, or, at least, the pride of Rufinus. At the moment when he flattered himself that he should become the father of a line of kings, a foreign maid, who had been educated in the house of his implacable enemies, was introduced into the Imperial bed; and Eudoxia soon displayed a superiority of sense and spirit, to improve the ascendant which her beauty must acquire over the mind of a fond and youthful husband.
