Dionysius now proceeded to Damascus, where he was honourably received by the governor, Barhebræus acting as interpreter. In these negotiations, however, Dionysius fell into a stupid blunder, exhibiting the letter of a Mongol magnate which had been intended for his supporters in Melatia. This caused great offence, for the Tartars were regarded as mortal enemies by the Moslems. It was only with great trouble, and through the intervention of Ibn Amíd (Elmacinus), the well-known Coptic author, that Dionysius at last succeeded in obtaining his diploma of confirmation on payment of a large bribe.

Barhebræus was soon afterwards named by Dionysius to be bishop of Aleppo; but on the installation there of a partisan of John’s, he withdrew, along with his father, to the Barsaumá monastery, where his patriarch was. John betook himself to the Armenian king of Sís, while Dionysius received recognition almost everywhere. Barhebræus soon again took up his abode in Aleppo. When the Mongols, who in the meantime had taken Bagdad (January 1258), entered Syria he wished to go to meet them, plainly with the object of securing mild treatment for the Christians. The idea was not unreasonable, for their common antipathy to Islam readily predisposed the Mongol chiefs in favour of the Christians, who, moreover, sought only toleration, and did not fight for sovereignty like the Moslems. Some of those wild Tartars had, moreover, been baptized, for the Nestorians had successful missions among the Turkish tribes. Dokuz Khatun herself, a wife of the sovereign Hulagu, who formerly had been one of the wives of his father Tuli, and who in accordance with Mongol custom had passed with the rest of the inheritance to the son, was a Christian, and did much for the protection and advantage of her co-religionists. But the attempt in this instance was unsuccessful. Barhebræus was detained at Kalat-Nejm, one of the Euphrates ferries; and Hulagu meanwhile coming to Aleppo, occupied the town, and inflicted on Moslems and Christians alike all the horrors of a sack (January 1260).

Dionysius compromised himself seriously. That he obtained letters of confirmation from the Mongol sovereign (1259) was not amiss, especially as the Seljuks and the Armenian Christian king had equally acknowledged the Tartar as their overlord. But it was a scandal that he connived at the robberies of the Christian subjects of the St. Barsaumá monastery, who had broken loose from all restraint in this period of general corruption and dissoluteness. And he finally lost the last shred of reputation by procuring the assassination of a cousin who had been a great trouble to him, and of his cousin’s brother, only a few days after a reconciliation had taken place; even the chronique scandaleuse of the history of the Jacobites supplied no parallel to such conduct. To escape the consequences of his deed the patriarch again went to Hulagu, and after overcoming many obstacles was lucky enough to secure his special protection, so that he was able to lord it more tyrannically than ever. And now the monastery of St. Barsaumá witnessed an unheard-of scene; the murderous patriarch was assassinated before the altar as he was holding a night service (17th-18th February) by a monk, a deacon, and a layman, nephew of one of the abbats. The assassins threw the “disciple” of the patriarch, who had been his instrument in the murder of his cousin, down the rock.

Whether Barhebræus had before these occurrences openly broken with Dionysius is not known; but one of his poems shows that latterly he was no longer at one with him, and some verses upon his death indicate that he regarded his assassination as a righteous judgment.

A Mongolian commissioner, himself a Christian, made his appearance for the punishment of the perpetrators of the deed. One of the abbats, who tacitly, at least, had approved it, was cruelly chastised and driven half-dead from the monastery. He was replaced by a brother of the priest and physician Simeon, who had risen to great favour with Hulagu, had grown very wealthy, and stood out as the main support of the Jacobites, in return for which he exercised influence in extraordinary ways in Church affairs. Some of the murderers and their accomplices were executed, and others committed suicide in prison.

By this shocking occurrence John became sole patriarch, and met with universal recognition; but he remained in Cilicia. Barhebræus now stood on good terms with him; and when he died in the spring of 1263, the bishop of Aleppo wrote in his honour a long poem commemorating his many excellences.

Abbat Theodore now hastened to the court, or rather to the camp, of the Mongolian sovereign to seek the patriarchate for himself. But Simeon the physician declined to undertake his cause, and also persuaded Barhebræus, who was also at that time at court, certainly not by mere chance, to oppose his claims. Barhebræus then proceeded to Cilicia and took part at Sís in the election of abbat Joshua, who, as patriarch, assumed the name of Ignatius (6th January 1264). Forthwith they proceeded to fill up also the office of maphrián, or primate of the Jacobites of the East, which had been vacant since June 1258. The origin of this dignity may be here explained. The Persian sovereigns had gradually suffered the Christians of various denominations in their empire to constitute themselves into distinct bodies, insisting, however, that while the head of each was to be independent of every external authority, he was to be in entire subjection to the throne.[[109]] These heads bore the title of “Catholicus.” The Syrian Monophysites did not receive a fixed constitution under a catholicus until a comparatively late date (in the sixth century); they stood in much closer connection with the Christians of the hostile empire of Rome than the Nestorians did, and, on the other hand, were much less able to compel recognition than the sometimes very warlike Monophysites of insubordinate Armenia. The main seat of the Jacobites of the Persian empire was the considerable town of Tagrít, on the middle course of the Tigris; but nowhere in Persia were they nearly so numerous as the Nestorians. The Jacobite catholicus bore also the title of maphrián (mafriyáná), i.e. “the fructifier,” who spreads the Church by instituting priests and bishops. After the Arabs had become masters of all the countries in which Monophysite Syrians were found, the separation of the provinces of the Jacobite “patriarch of Antioch” and that of the maphrián was, strictly speaking, no longer necessary; but the force of custom, and still more the interest which many of the clergy had in not allowing so influential and remunerative a post as that of maphrián to go down, were enough to maintain the old arrangement. But many disputes arose as to the boundaries of the two provinces, and the whole relation of maphrián to patriarch; on the whole, however, it was agreed that the patriarch’s indeed was the higher rank, but that the maphrián in his sphere was quite independent of him; and further, that for the election of a patriarch the co-operation of the maphrián was indispensable (unless that post also was vacant), and that a maphrián could only be nominated with the sanction of the patriarch. In the choice of a maphrián the wishes of the Eastern dioceses (i.e. of the bishops and heads of monasteries there) had to be respected; yet, as a rule, he was taken from the West. Now Barhebræus had already been designated as maphrián by the late patriarch, and, moreover, he seems to have been the ruling spirit in the electoral synod; accordingly he was chosen “maphrián of Tagrít and the East” on Sunday, 20th January 1264. The Armenian king with his suite and officials, spiritual and secular, were present at his consecration on the same day in the church of the Theotokos at Sís. Barhebræus preached the sermon, which an interpreter translated into Armenian. The Armenians, be it noted in passing, were of the same creed as the Jacobites, but differed from them on many points of ritual, and perhaps also in some subordinate matters of dogma. Armenians and Jacobites were thus very ready to suspect one another of heresy, and at best there was little love lost between the two parties.[[110]] After patriarch and maphrián had received their diplomas of confirmation from the Mongol sovereign (whose assent had doubtless been secured before the election) they withdrew, the one to Asia Minor and the other to Mosul.

The Jacobites of the East had long been without any proper government; for the predecessor of Barhebræus, his old fellow-student at Tripoli, had failed to establish his authority in the East, and soon withdrew into Syria, and after his death the vacancy had continued for nearly six years. The lands of the Tigris were terribly wasted. Although the Mongols still were more favourable to the Christians than to the Moslems, they were neither willing nor able to spare them in those wholesale massacres which constantly occurred. Moreover, the position of the Christians, which was one of greater friendliness with the Mongols, and thus gave them a somewhat more self-reliant bearing, repeatedly excited the jealousy and fanaticism of the Mohammedan population, which was greatly superior in numbers and in strength; in the district of Mosul, in particular, many bloody encounters took place. Matters were better in Aderbiján (north-western Media), the favourite seat of the Mongolian rulers. There, until the reaction set in, the Christians suffered little molestation, and monasteries and churches arose in the capital cities of Merághá and Tabríz. The Jacobites were here less numerous than either Armenians or Nestorians. Barhebræus now laboured indefatigably as maphrián for the strengthening of his Church. He made many extensive journeys within his territory, took measures for the erection of ecclesiastical edifices, and consecrated numerous priests and bishops. He succeeded in maintaining good relations with the Mongolian court without coming into too close contact with it. And with all this he studied, wrote, and taught without intermission.

At Mosul the maphrián was met in solemn procession by the officials of the Mohammedan prince as well as by the Christians: the vassal of the Mongols had good reason for treating in a friendly way a man of mark who had just been the recipient of their favour. Still more solemn was the reception of Barhebræus when, at Easter 1265, he came to Bagdad—still an important place, notwithstanding its recent terrible sack. Such was the consideration enjoyed by Barhebræus, that even the catholicus of the Nestorians sent a deputation, including two of his own nephews, to escort him into his presence. A harmony like this, between the representatives of two creeds which had been separated by the hostility of eight centuries, is well worth remarking. Many Nestorians took part also in the service held by Barhebræus, at which was wrought the customary miracle of a spontaneous overflow of the chrism at the moment of consecration.[[111]] The catholicus, indeed, presently became jealous of his colleague’s popularity, but no mischief followed, for he died a fortnight after the festival (Saturday, 18th April 1265). After spending the entire summer in Bagdad, and consecrating numerous clergy of various grades, Barhebræus returned again to the district of Mosul, where his proper see was. He usually lived in the great fortified monastery of St. Matthew, which was for the maphrián something like what that of Barsaumá was for the patriarch.

The patriarch Ignatius, in the years immediately following, fell into a violent dispute with the physician Simeon, already mentioned, who had taken possession of the government of the monastery of Barsaumá. As he had done this on the strength of orders issued by the Mongols, Ignatius sought to obtain from these a decision in an opposite sense; and although Barhebræus earnestly urged him to come to some amicable settlement of the difficulty, and not to expose himself before “the barbarian Huns,” he persevered in the line he had chosen. The maphrián naturally took this very ill. When, accordingly, in 1268, in the course of a journey westward to visit his relatives near Lake Van, he encountered the patriarch on his way to the Mongol court to complain of Simeon, he sought to avoid a meeting, and the patriarch obtained one at last only with difficulty. Abaga, who had succeeded his father Hulagu in the sovereignty of the Mongols in February 1265, actually promulgated a decree in accordance with the wishes of Ignatius; but the influential Simeon contrived that it should straightway be cancelled by another, and Barhebræus, detained in Cilicia by a serious illness, saw Simeon return in triumph with the decree in his hand. But the dispute was further prolonged. The Government pronounced alternately for this party and for that; neither reconciliation nor compromise proved permanent. At last, in 1273, Barhebræus, who had been called in as arbiter, was successful in composing the difference. On this occasion he found his native land in poor case. Moslem troops from Syria had invaded the Mongol territory, wasting it far and wide, and dragging many Christian women and children into slavery. The lords of Egypt and the petty princes of Syria were at that time at continual war with the Tartars, whom in the end they succeeded in shaking off; but the struggles in the meantime had completed the ruin of many districts. Additional insecurity was caused by the presence of robber tribes, which now could do pretty much as they pleased. Barhebræus, who had taken up temporary quarters in the monastery of St. Sergius, was escorted thence to that of St. Barsaumá by a body of fifty armed dependants.
