In spite of that zeal for true religion, the modern reader will not have followed the career of Irene up to this point with unalloyed admiration. She was essentially a casuist, the very embodiment of the Byzantine religious spirit. Chaste she undoubtedly was, though we shall presently find her acting in that regard in drastic contradiction to the teaching of the Church; she was generous, even extravagant, with money, and she showed a sincere concern for the welfare of her subjects within the limits of her own ambition; but she betrays from the start that lack of moral scrupulousness which too often accompanies fervent piety in Byzantine women, and the bitter disappointment which closes the first part of her reign will now make her more unscrupulous than ever.

It was in October 790 that Irene was deposed. Fourteen months afterwards we find her returning to imperial power and making a fearful use of it. Constantine had yielded to her pressure and that of the nobles devoted to her, and again proclaimed that she was Empress and co-ruler of the Empire. The Armenian troops at once protested against the change, and, as their commander, Alexius, was in Constantinople at the time, he was scourged and converted into an abbé malgré lui. An expedition against the Bulgarians failed shortly afterwards, and, whether the failure did really lead to a conspiracy, or the plot was invented to serve the purpose of Irene and Constantine, a terrible clearance was made of their possible opponents. Alexius and Nicephorus (the uncle of the Emperor who had been made a cleric) had their eyes cut out; and three other sons of Eudocia were brought from their clerical homes and had their tongues cut. We must not too readily implicate Irene in these barbarities. She had not returned to her former influence and activity, and it was Constantine himself who led an army against the insurgents in Armenia and made a terrible end of their rebellion. In view, however, of Irene’s later behaviour, it is probable that she agreed to, if she did not inspire, these proceedings, and the authorities assure us that she now began to make selfish profit of the unpopularity of her son and encourage him in licence.

We have as yet said nothing of the imperial life of the young woman who had passed from her village home to the palace. The reason is that she seems to have been one of those admirable Empresses who impress the chroniclers only when they bear children or suffer misfortune. Maria had borne two daughters to Constantine, and the year of her misfortune was at hand. Constantine had never loved his wife and had freely sought consolation elsewhere; and in the year 794 his eye fell on a charming lady of his mother’s suite. Whether this lady was too chaste or too ambitious to admit his passion irregularly, we cannot say, but we have the emphatic assurance of the authorities that Irene encouraged the passion, and supported her son in his proposal to divorce Maria, in order still further to weaken his position. If such an act seem beyond the range of a mother’s ambition, I can only say that far worse is to follow.

On 3rd January 795, the unfortunate Maria was deposed from her dignity, exchanged her imperial robes for the rough black dress of a nun, and, with shorn hair, passed to a convent; and before the end of the same year the more fortunate Theodote was transferred from the service of Irene’s chamber (cubicularia) to the imperial dignity. It need hardly be said that this procedure was violently opposed to the solemn teaching of the Church, which now regarded marriage as absolutely indissoluble. The courtly patriarch Tarasius, who had been converted from a very secular secretary into an archbishop, proved accommodating enough; he declined to perform the marriage, but he permitted some enterprising priest named Joseph to do so, and he sanctioned the transfer of Maria to a nunnery. But the monks of the Empire raised once more their formidable chant of execration, and showered epithets on the Emperor and the archbishop. The great monastery of Saccudion, in Bithynia, was the centre of the agitation, under its vigorous abbot Plato.[17]

The next move of Irene was to espouse the cause of the monks who fulminated against her adulterous son and his “Jezebel,” and were punished for doing so. If we feel a scruple about admitting so malignant a course in a Christian mother, we must remember that these things are ascribed to her by chroniclers who are full of admiration for her piety, and that the tragic end of the story is quite beyond doubt. Constantine lost ground, and Irene watched her opportunity. It came in the month of September 796, when mother and son went, with a large and distinguished company, to take the hot baths at Prusia. Theodote had remained behind, so as to be near the Porphyra palace, and she presently sent a message that a son was born. Constantine galloped in delight to the city, and Irene set to work. By amiable conversation and secret gifts she won a number of the officers, and the conspiracy quietly proceeded when they returned to Constantinople. The following summer Constantine set out against the Saracens, and Irene, fearing that he might return with glory and renewed popularity, for he was a skilful and vigorous soldier, determined to strike.

Constantine was recalled to the city by some false intelligence, and as he went one day (17th June) from the Hippodrome to join his wife (whose baby had recently died) in the palace of Blachernæ, he was attacked. He escaped, and fled by boat to the Asiatic side, where Theodote joined him. The position was now critical, as a number of nobles and officers were with Constantine, and Irene heard that others were daily crossing the water. For a moment she trembled and thought of sending bishops to ask her son to allow her to retire into private life, but there remained one device. Among the courtiers with Constantine were some whom she had already compromised, and she sent a secret message to these men to the effect that she would reveal their perfidy to the Emperor if they remained with him. The stratagem succeeded. In the early morning of 15th August the Emperor was brought, bound, to his palace and lodged in the Porphyra; and there, in the very palace in which he had been born, his eyes were brutally cut out by the knives of the soldiers at the ninth hour of the day. Some of the chroniclers observe that the work was done in such a way that the men really intended to kill Constantine. That is misleading, since it would have been perfectly easy to kill him, whereas we know that he lingered in confinement in the Therapia palace for some years. The truth probably is that Irene’s casuistry permitted the horrible mutilation, but forbade the murder, of her son; but her agents probably concluded that if they accidentally and unintentionally killed Constantine there would be few tears shed.

It would be difficult to find a parallel to this horrible deed in the long story of the pagan Empresses, and we press on to the conclusion of Irene’s reign. For several years she continued to rule the Empire in peace and prosperity. One or two feeble revolts were made, and more eyes were cut from their sockets, but the year 799 opened with little sign of trouble. Decrees went forth in the name of “Irene, the great king and autocrat of the Romans.” She built convents and established charitable foundations. She gladdened the hearts of the poor by remitting taxes and import duties, and scattering money amongst them as she rode to church in a golden chariot drawn by four white horses, the reins of each held by one of the highest dignitaries of the Empire. The Pope blessed her—he had put out the eyes of his predecessor—and the great Charlemagne sent legates to ask her hand in marriage. And the blind Emperor lingered in his palace-prison with his faithful Theodote, waiting for the thunder of Jupiter.

In the year 800 the shadow of the avenger seemed to come over the palace. Irene had two powerful ministers, Stauracius (who had, of course, returned from the service of the altar) and Aetius, and their quarrels filled the palace and the heart of Irene with bitterness. In 799 she had been dangerously ill, and their intrigues had doubled. She recovered, and Stauracius determined to make a bold attempt to secure the purple. His conspiracy was discovered, and Irene, holding a council in the gold-roofed dining-hall, decreed that no military officer was to approach Stauracius. The sentence seems mild, but the truth was that, in spite of doctors and priests who lied to him even as he spat blood, Stauracius was dying. He passed away in June, and Aetius commanded the palace.

The end came in 802. Aetius had frustrated the proposal of a marriage of Charlemagne and Irene, who seems to have favoured it (she was still only in her fiftieth year), because he designed to secure the purple for his brother and thus maintain his position. But the legates of Charlemagne lingered in Constantinople, and witnessed the fall of the great Empress. On the evening of 31st October 802, when Irene lay ill in her Eleutherian palace, a group of nobles and officers knocked at the door of the Chalke and summoned the guard. They had, they said, been sent by Irene to put Nicephorus, the “chancellor of the exchequer,” on the throne; she wished to forestall Aetius. In the darkness and confusion they were admitted, and they took possession of the palace and set guards round the Eleutherian palace. Almost before dawn the next morning they conveyed Nicephorus to the great church to be crowned, and, although Irene’s liberality had won the people and they gathered in the square to damn Nicephorus and the archbishop and raise cheers for Irene, they were powerless. The nobles and officers were resolved to tolerate the insolence of Aetius no longer.

Irene, sick and dispirited, was incapable of making one of those spurts of energy or astute stratagems which had so often saved her. When the hypocritical Nicephorus came to visit her in her apartments, she quietly begged that she might be permitted to end her days in her Eleutherian palace. He had often been a guest at her table and grossly deceived her; even the nobles were yet to learn what a brute they had put on the throne. He promised that if she would swear on the cross to give up the whole of the imperial treasure, she should retire to her palace. It was believed that treasure was hidden in various places in that labyrinth of palaces; even the blind Constantine was brought forth to say in which wall a certain treasure was hidden. Irene swore her last oath, gave a list of the hiding-places—and was promptly imprisoned in a monastery she had built on the Princes’ Islands, a group of small islands, in view of the palace, on the Sea of Marmora.
