Michael now returned to the problem of John, and, when he remarked to his courtiers that it was absurd to have “two heads under one hat,” they knew that the youth was doomed. We have no reason to doubt the statement of the chronicler that Eulogia supported him in this design, but we may at least assume that the manner of executing it was due to Michael alone. He ordered that the harmless and helpless young man should be blinded. A long experience had made the Greeks ingenious in this operation, and, instead of removing the eyes with knives, or using hot irons, they now sometimes blinded a man by an elaborate concentration of intense light on the retina or by the use of boiling vinegar. The more humane method of blinding by an intense light was used in the case of John, and the unfortunate youth was then incarcerated for life in a fortress on the coast of Bithynia. This ghastly operation was performed on the day on which the churches and monasteries of the Byzantine Empire offered their clouds of incense in honour of the birth of Christ. It is at least gratifying to find that it did not pass without protest. A warm-hearted youth attached to the Court lost his nose and lips for speaking too freely about it, and many others had to be punished. Theodora seems to have been a silent, perhaps disgusted, witness of her husband’s course, and there is some faint evidence that Michael’s elder sister dissented from it. In fact, the patriarch Arsenius himself openly resented this flagrant violation of a thrice-repeated oath, and thus led to a long and fierce ecclesiastical struggle in which the two royal nuns were actively engaged. The patriarch’s procedure was not as emphatic and thorough as it ought to have been, but he at least distinguished himself among the crowd of corrupt and servile bishops and abbots by more or less excommunicating Michael. A council of bishops then obliged the Emperor by deposing Arsenius and putting a more courtly prelate in his place, but the hostility and derision of the people soon induced Germanus to retire, and a clerical diplomatist named Joseph occupied the see. As the furious schism of the Arsenians and the Josephites, which followed, will cross the lines of our story for some time to come, it is necessary to introduce this fragment of ecclesiastical history. For the moment it is enough to say that in 1268 the patriarch Joseph absolved from his sin the ostentatiously penitent Emperor, before a crowd of weeping Senators and priests.
