John had an ingenuous and amiable daughter who seems to have been not unacquainted with the political situation. Twice had the brilliant Belisarius been withdrawn to the city in a fit of jealousy, and there were rumours that the strong man was wearying of serving an Emperor who could do nothing but employ others and reap their glory. Antonina won her way to the heart and confidence of the girl, and betrayed to her that her husband was secretly disaffected. The artless Euphemia hastened to tell her father that there was a prospect of overthrowing Theodora, whom they both hated. Even John was deceived by the astute adventuress. It was arranged that Antonina should go to her suburban palace and meet John there during the night. We do not know that Theodora had a share in framing this diabolical plot, but it was now communicated to her by Antonina, and she at once pressed it and used her resources for carrying it out with safety. In the dead of the following night John entered the palace of the unscrupulous adventuress and listened to her whispers of treachery. Procopius says that Theodora had initiated the Emperor to the plot, and he had consented, but at the last moment sent a messenger to John not to see Antonina. This seems to be a piece of polite fiction in the interest of the Emperor; it is incredible that an astute and experienced minister would risk his neck after such a message. John went, and, in the apparently lonely palace, spoke his secret sympathy with the supposed design of Belisarius. No sooner had he uttered the words than a troop of imperial guards entered the room to arrest or assassinate him, but John also had brought soldiers and they enabled him to escape. Had John gone straight to the palace of Justinian, he might still have saved his position. Instead, he fled nervously to the sanctuary, and Theodora hardened the mind of her husband. The wealthy and powerful noble was stripped of his estates and forced to enter the ranks of the clergy--one of the quaintest penalties of the time--in the suburb of Cyzicus. There the people whom he had oppressed might behold their once powerful enemy, the secret pagan and Sybarite, shaven and humiliated. It appears that Theodora was not yet satisfied, though she is not directly implicated by Procopius in the last act of the tragedy. The Bishop of Cyzicus was murdered, and as John was one of his many bitter enemies, he was arrested, scourged, and driven into exile and poverty. The fate of the unhappy Euphemia is unknown; she was probably compelled to enter a nunnery and weep there over the memory of the imperial tigress and her friend.
