From his early tolerance Justin had passed to the temper of the persecutor, and the groans of the Monophysites were heard throughout the Empire. Whether this new phase of activity contributed to, or resulted from, his growing insanity, and how far Sophia was implicated in it, we do not know; but by the year 574 Justin had become a dangerous maniac. Bars had to be placed at his windows, and his servants had carefully to avoid the imperial teeth; while, in his less dangerous hours, he would shriek with delight, or bark like a dog, as the servants pulled him along the corridors in a small cart fitted with a throne. The commander of the Excubitors who guarded or amused him was a tall and very handsome Thracian officer named Tiberius, whose fine bluish eyes, light hair and beard, fresh florid complexion and manly form, pleased the eye of the Empress, and she induced Justin, in a lucid hour toward the end of the year 574, to raise him to the rank of Cæsar. Writers of the time describe with great feeling this last sane act of Justin II. The Empress, the patriarch and his clergy, and the nobles and Senators, were summoned to the palace, and Justin held to them a long and deeply penitent discourse, lamenting his sins and cruelty, and recommending his wife and his Empire to the fortunate Tiberius. The scepticism of the historian is apparently silenced by the weighty assurance of Bishop John that this remarkable speech of the insane ruler was taken down in shorthand,[11] but the publication of such a statement would be by no means inconsistent with the character of Sophia, and we must interpret the narrative with some liberality. In most of the historians we read that, when Justin died and Tiberius ascended the throne, a romantic scene was witnessed in the Hippodrome and the astute Sophia was outwitted by her handsome favourite. Sophia, it is said, proposed to marry him, but when the crowd in the Hippodrome cried, “Let us see a Roman Empress,” he replied, through the herald, that an Empress already existed, and that her name was similar to that of a church in the city, the position of which he indicated. The citizens at once solved the conundrum, acclaimed his secret wife Anastasia, and laughed at the discomfiture of Sophia, who retired to her palace in anger and mortification.
