in the year 428 began to propagate his heresy, denying the hypostatic union. The Council of Ephesus denounced him, and, in spite of the emperor and court, Nestorius was anathematized and driven into exile. His sect spread through the East, and became a flourishing Church. It reached to China, where the emperor was all but converted; its missionaries traversed the frozen tundras of Siberia, preaching their maimed Gospel to the wild hordes which haunted those dreary wastes; it faced Buddhism and wrestled with it for the religious supremacy in Thibet; it established churches in Persia and in Bokhara; it penetrated India; it formed colonies in Ceylon, in Siam, and in Sumatra; so that the Catholicos or Pope of Bagdad exercised sway more extensive than that ever obtained by the successor of S. Peter. The number of Christians belonging to that communion probably exceeded that of the members of the true Catholic Church in East and West. But the Nestorian Church was not founded on the Rock, it rested on Nestorius, and when the rain descended, and the winds blew, and the floods came, and beat upon that house, it fell, leaving scarce a fragment behind.

Rubruquis the Franciscan, who in 1253 was sent

on a mission into Tartary, was the first to let in a little light on the fable. He writes, "The Catai dwelt beyond certain mountains across which I wandered, and in a plain in the midst of the mountains lived once an important Nestorian shepherd, who ruled over the Nestorian people, called NayWhen Coir-Khan died, the Nestorian people raised this man to be king, and called him King Johannes, and related of him ten times as much as the truth. The Nestorians thereabouts have this way with them, that about nothing they make a great fuss, and thus they have got it noised abroad that Sartach, Mangu-Khan, and Ken-Khan were Christians, simply because they treated Christians well, and showed them more honour than other people. Yet, in fact, they were not Christians at all. And in like manner the story got about that there was a great King John. However, I traversed his pastures, and no one knew any thing about him, except a few Nestorians. In his pastures lives Ken-Khan, at whose court was Brother Andrew, whom I met on my way back. This Johannes had a brother, a famous shepherd, named Unc, who lived three weeks' journey beyond the mountains of Caracatais."

This Unk-Khan was a real individual; he lost

his life in the year 1203. Kuschhik, prince of the Nayman, and follower of Kor-Khan, fell in 1218.

Marco Polo, the Venetian traveller (1254—1324), identifies Unk-Khan with Prester John; he says, "I will now tell you of the deeds of the Tartars, how they gained the mastery, and spread over the whole earth. The Tartars dwelt between Georgia and Bargu, where there is a vast plain and level country, on which are neither cities nor forts, but capital pasturage and water. They had no chief of their own, but paid to Prester Johannes tribute. Of the greatness of this Prester Johannes, who was properly called Un-Khan, the whole world spake ; the Tartars gave him one of every ten head of cattle. When Prester John noticed that they were increasing, he feared them, and planned how he could injure them. He determined therefore to scatter them, and he sent barons to do this. But the Tartars guessed what Prester John purposed

and they went away into the wide wastes of the North, where they might be beyond his reach." He then goes on to relate how Tschengis(Jenghiz-)Khan became the head of the Tartars, and how he fought against Prester John, and, after a desperate fight, overcame and slew him.

The Syriac Chronicle of the Jacobite Primate, Gregory Bar-Hebræus (born 1226, died 1286), also identifies Unk-Khan with Prester John. "In the year of the Greeks 1514, of the Arabs 599 (A.D. 1202), when Unk-Khan, who is the Christian King John, ruled over a stock of the barbarian Hunns, called Kergis, Tschengys-Khan served him with great zeal. When John observed the superiority and serviceableness of the other, he envied him, and plotted to seize and murder him. But two sons of Unk-Khan, having heard this, told it to Tschengys, whereupon he and his comrades fled by night and secreted themselves. Next morning Unk-Khan took possession of the Tartar tents, but found them empty. Then the party of Tschengys fell upon him, and they met by the spring called Balschunah, and the side of Tschengys won the day; and the followers of Unk-Khan were compelled to yield. They met again several times, till Unk-Khan was utterly discomfited and was slain himself, and his wives, sons, and daughters carried into captivity. Yet we must consider that John, king of the Kergis, was not cast down for nought, nay rather, because he had turned his heart from the fear of Christ nis Lord, who had exalted him, and had taken a

wife of the Zinish nation, called Quarakhata. Because he forsook the religion of his ancestors and followed strange gods, therefore God took the government from him, and gave it to one better than he, and whose heart was right before God."

Some of the early travellers, such as John de Plano-Carpini and Marco Polo, in disabusing the popular mind of the belief in Prester John as a mighty Asiatic Christian monarch, unintentionally turned the popular faith in that individual into a new direction. They spoke of the black people of Abascia in Ethiopia, which, by the way, they called Middle India, as a great people subject to a Christian monarch.

Marco Polo says that the true monarch of Abyssinia is Christ; but that it is governed by six kings, three of whom are Christians and three Saracens, and that they are in league with the Soudan of Aden.

Bishop Jordanus, in his description of the world, accordingly sets down Abyssinia as the kingdom of Prester John; and such was the popular impression, which was confirmed by the appearance at intervals of ambassadors at European courts from the King of Abyssinia. The discovery of the Cape of Good Hope was due partly to a desire
