In the spring of 629 Heraclius took the cross back to its original shrine at Jerusalem, and from that time spent nine years in the provinces of Palestine, Syria and Asia Minor. During those years the Mohammedan power became a formidable menace to the Roman Empire, and the inaction of Heraclius is a scandal to historians. His nervous system was strained to the verge of insanity, and he retreated like one paralysed with terror before the advance of the Mohammedans. Martina foresaw the end, and began to prepare for the succession. There can be no doubt that in these later years Heraclius, whose religious fervour was now greatly increased, was troubled by the cry that his “incestuous” marriage had brought these troubles on the Empire. When his nephew Theodore retreated before the invincible Arabs, and came to reproach Heraclius for his “sin,” the Emperor sent him under guard to Constantinople and ordered that he should be disgraced. Some writers see in this the action of Martina, but it may quite well have been due to the broody nervousness of Heraclius himself.
It was plain that Heraclius would not stem the Mohammedan tide, and everywhere men talked of the succession. By the year 638 he and Martina were back in the Hieria palace, and the struggle deepened. Heraclius had now two children by his first wife Eudocia, and five (living) children by Martina. His eldest child, Epiphania Eudocia, had narrowly missed a romantic career. During the Persian war Heraclius had struck an alliance with the King of the Khazars, a wild people akin to the Huns, and, after gorgeously entertaining and rewarding him, had shown him a miniature of his beautiful daughter, then fifteen years old, and offered him her hand. It was only the death of the King in the next year that saved the delicate young girl from being added to the rude harem of the Hunnic prince. She was still unmarried. Her brother, Heraclius Constantinus, now twenty-six years old, was already associated in the Empire, and was the obvious heir to supreme power. But both Heraclius and Martina knew that the Emperor’s death would at once set her religious enemies to work to eject her and her children from the palace, and they were anxious to secure her position by associating her eldest son, Heraclonas, in the Empire. There were, besides, a natural son of Heraclius by an early concubine, named Athalaric, and the sons of his cousin Nicetas, who had helped him to win the Empire.
Two of these possible candidates for the purple were summarily dismissed. Athalaric and the nephew Theodore were charged with conspiracy at Constantinople, their hands and feet were struck off, and they were sent into exile. It is conjectured by some writers on Martina that she dictated this heavy punishment, and that her hand is seen in the events which follow. Of this there is no proof; but there can be no doubt that she was eager to secure the succession of Heraclonas, and that Heraclius was now an almost feeble-minded patient under her care. He persistently refused to cross the strip of water from Hieria to the city, and they were compelled at length to make a bridge of boats across the narrower part of the strait, and place artificial hedges of trees along its sides, so that he could ride to Constantinople without catching sight of the sea. The young Constantine, his eldest son, had inherited the delicacy of his mother, and it was necessary to provide for the event of his death. Should his sons inherit the purple, or should it pass to “the children of incest”? The city seethed with discussion.
In the final decision we may confidently recognize the voice of Martina. On 4th July 638 Heraclonas, then a boy of fifteen years,[14] was crowned in the palace by the patriarch Sergius; a younger son, David, was raised to the same dignity shortly afterwards, and the young daughters of Martina, Augustina and Martina, were entitled Augustæ. On the 1st of January 639 three Emperors rode in the procession: Heraclius, Constantine and Heraclonas. Martina had, apparently, triumphed; but more prudent citizens must have shaken their heads in reflecting on the struggle which would inevitably follow the death of Heraclius.
The Emperor lingered for more than two years in his impotent condition, and Martina meantime found a fresh and most powerful ally. The patriarch Sergius had died soon after crowning Heraclonas, leaving his metropolitan see to a monk, Pyrrhus, whom he had raised to the higher rank of the clergy. Pyrrhus became an ally of the Empress, who may possibly have assisted in his elevation, and the alliance was the stronger because Pyrrhus secretly favoured the sect of the Monophysites. From Constantine he would receive little encouragement, whereas Martina, as events proved, was ready to allow him to impose his metaphysical distinction on the Church in return for his political support. It is even said that Martina urged her husband to send the weakly Constantine against the Mohammedans, in the hope that he would not return. Such things are easily said, and easily believed, but incapable of proof.
In February 641 Heraclius died. He suffered in his last years from dropsy, and those who are curious to know by what appalling means the medical men of the time relieved such an affliction, and how the theologians of the time placidly traced the operation of a divine curse for marrying one’s niece, may read the details of his sufferings in the patriarch Nicephorus. To the last Heraclius was faithful to his beloved wife. He divided the government of the Empire equally between Constantine and Heraclonas, and he entrusted to the patriarch Pyrrhus a large sum of money to be given to Martina in the event of her enemies succeeding in driving her from power. The struggle began at once.
Martina convoked a meeting of the citizens—presumably in the Hippodrome—and had the will of Heraclius read to them. When the herald had concluded, the sullen silence was broken by a cry for the Emperors. Martina, who was evidently minded to keep the youths in the background and govern in their name, summoned the Emperors, but continued to act as mistress of the Empire. But Constantinople—a compound of inferior Greek and Roman with Syrian blood—always disliked feminine rule, and in face of the advancing Mohammedans regarded it with additional concern. “Honour to you as mother of the Emperors,” the citizens cried, “but to them as Emperors and lords. You, mistress, would not be able to resist and reply to barbarians and foreigners coming against the city. God forbid that the Roman commonwealth should fall so low.” We may take it that the chronicler has gathered into a speech the various murmurs which arose from the crowded benches of the Hippodrome. Plausible as the cry was, it was a grave blunder. The ailing, probably consumptive, Constantine had not the manliness of a ruler, and the palace became the theatre of the struggles of rival courtiers.
On the side of Constantine was the imperial treasurer Philagrius, and this man embittered the situation by informing the young Emperor of the money which Heraclius had left in charge of the archbishop and forcing him to pay it into the treasury. In order further to strengthen his position Philagrius represented to Constantine that his children would be in danger from Martina if he died. It is important to notice that the death of Constantine was plainly expected by all parties. Nothing is clearer than that he had inherited the delicacy of his mother, and was either epileptic or consumptive—more probably consumptive. The patriarch Nicephorus tells us that he was “chronically ill” and lived in a palace he had built at Chalcedon for the sake of his health. His Empress, Gregoria Anastasia, was a daughter of Nicetas, the young cousin who had set out from Africa with Heraclius, but we have no further information about her. For her sake and that of the children Constantine was persuaded by his intriguing courtiers to send an officer, Valentine, to the troops when he felt that his end was near. Valentine had not only a letter urging the troops to protect Constantine’s children from Martina, but a large sum of money to distribute amongst them. It is strange that historians have overlooked this very obvious intrigue and so easily accepted the clerical prejudice against Martina. If Martina were unable to meet “barbarians and foreigners”—a point which might be disputed—assuredly infants could not be trusted to do so.
Constantine died about three months after the death of his father. There is no serious ground whatever for the charge that he was poisoned by agents of Martina and Pyrrhus. The patriarch Nicephorus, the best authority, knows nothing of the rumour, and the very chroniclers, of a later date, who attach importance to it admit that Constantine suffered from a chronic malady. Indeed, when we find a contemporary (and recently published) ecclesiastical writer, the Bishop of Nikin, saying that Constantine after three months’ illness “vomited blood, and when he had lost all his blood he died,” we may confidently acquit Martina, and conclude that the young Emperor died of consumption. The statement of Constantine’s son, a boy of eleven, when he came to the throne, that Pyrrhus and Martina had been justly punished, is a mere echo of the pretext of those who deposed her. The poisoning of a consumptive youth would be a new and superfluous crime, and we have no reason to think that Martina was even normally criminal.
Martina at once assumed the government in the name of her son and expelled the hostile faction from the Court. Philagrius was visited with the most humane punishment of the time—he was forced to become a priest—and his friends were dispersed. But his emissary Valentine was in a strong position and he determined to put it to account. The large sum of money entrusted to him enabled him to purchase the devotion of an army, and he settled at Chalcedon with the ostentatious design of seeing that no evil was done to the young son of the late Emperor. Martina cleverly foiled his first move. She directed Heraclonas to become godfather to the boy, who was carefully kept in the palace at Constantinople, and to swear, with his hand on the cross, that no harm should be done to the child. Valentine then brought his troops nearer and began to ravage the suburbs and neighbourhood of the city, while his friends in Constantinople lit the flame of religious antagonism to Pyrrhus, who was unfortunately pressing his Monophysite tenets on the Church. Exasperated at the inconveniences of the siege and the heresy of the patriarch, the citizens now became restive. A mob invaded and pillaged the great church of St Sophia, and Pyrrhus was forced to abdicate. The power of Martina was now dangerously enfeebled, and she came to terms with Valentine. The ambitious officer was to be appointed “Count of the Excubitors,” or commander of the heavier guards, and to be excused from rendering an account of the money entrusted to him.
