I, Friar John of Monte Corvino, of the Order of Friars Minor [The Franciscans], departed from Tauris, a city of the Persians, in the year of the Lord 1291, and proceeded to India. And I remained in the country of India, wherein stands the church of St. Thomas the Apostle, for thirteen months, and in that region baptized in different places about one hundred persons. The companion of my journey was Friar Nicholas of Pistoia, of the Order of Preachers [The Dominicans], who died there, and was buried in the aforesaid church.
I proceeded on my further journey and made my way to Cathay [China], the realm of the emperor of the Tatars who is called the Grand Khan. To him I presented the letter of our lord the pope, and invited him to adopt the Catholic faith of our Lord Jesus Christ, but he had grown too old in idolatry. However he bestows many kindnesses upon the Christians, and these two years past I am abiding with him.
The Nestorians, a certain body who profess to bear the Christian name, but who deviate sadly from the Christian religion, have grown so powerful in those parts that they will not allow a Christian of another ritual to have ever so small a chapel, or to publish any doctrine different from their own.
To these regions there never came anyone of the apostles, nor yet of the disciples. And so the aforesaid Nestorians, either directly or through others whom they bribed, have brought on me the sharpest of persecutions. For they got up stories that I was not sent by our lord the pope, but was a great spy and impostor; and after a while they produced false witnesses who declared that there was indeed an envoy sent with presents of immense value for the emperor, but that I had murdered him in India and stolen what he had in charge. And these intrigues and calumnies went on for some five years. And thus it came to pass that many a time I was dragged before the judgment seat with ignominy and threats of death. At last, by God's providence, the emperor, through the confessions of a certain individual, came to know my innocence and the malice of my adversaries; and he banished them with their wives and children.
In this mission I abode alone and without any associate for eleven years, but it is now going on for two years since I was joined by Friar Arnold, a German of the province of Cologne.
I have built a church in the city of Khanbaliq [modern Beijing], in which the king has his chief residence. This I completed six years ago; and I have built a bell tower to it, and put three bells in it. I have baptized there, as well as I can estimate, up to this time some 6,000 persons; and if those charges against me of which I have spoken had not been made, I should have baptized more than 30,000. And I am often still engaged in baptizing.
Also I have gradually bought one hundred and fifty boys, the children of pagan parents, and of ages varying from seven to eleven, who had never learned any religion. These boys I have baptized, and I have taught them Greek and Latin after our manner. Also I have written out Psalters for them, with thirty hymnaries and two breviaries. By help of these, eleven of the boys already know our service, and form a choir and take their weekly turn of duty as they do in convents, whether I am there or not. Many of the boys are also employed in writing out Psalters and other things suitable. His Majesty the emperor moreover delights much to hear them chanting. I have the bells rung at all the canonical hours, and with my congregation of babes and sucklings I perform divine service, and the chanting we do by ear because I have no service book with the notes.
A certain king of this part of the world, by name George, belonging to the sect of Nestorian Christians, and of the illustrious family of that great king who was called Prester John of India, in the first year of my arrival here attached himself to me, and being converted by me to the truth of the Catholic faith, took the lesser orders, and when I celebrated mass he used to attend me wearing his royal robes. Certain others of the Nestorians on this account accused him of apostasy, but he brought over a great part of his people with him to the true Catholic faith, and built a church on a scale of royal magnificence in honor of our God, of the Holy Trinity, and of our lord the pope, giving it the name of the Roman Church.
This King George six years ago departed to the Lord a true Christian, leaving as his heir a son scarcely out of the cradle, and who is now nine years old. And after King George's death his brothers, perfidious followers of the errors of Nestorius, perverted again all those whom he had brought over to the church, and carried them back to their original schismatical creed. And being all alone, and not able to leave his Majesty the khan, I could not go to visit the above-mentioned church, which is twenty days' journey distant.
Yet, if I could but get some good fellow-workers to help me, I trust in God that all this might be retrieved, for I still possess the grant which was made in our favor by the late King George before mentioned. So I say again that if it had not been for the slanderous charges which I have spoken of, the harvest reaped by this time would have been great!
Indeed if I had had but two or three comrades to aid me 'tis possible that the emperor khan would have been baptized by this time! I ask then for such brethren to come, if any are willing to come, such I mean as will make it their great business to lead exemplary lives . . .
As for the road here I may tell you that the way through the land of the Goths subject to the emperor of the Northern Tatars, is the shortest and safest; and by it the friars might come, along with the letter-carriers, in five or six months. The other route again is very long and very dangerous, involving two sea-voyages; the first of which is about as long as that from Acre to the province of Provence, while the second is as long as from Acre to England. And it is possible that it might take more than two years to accomplish the journey that way. But, on the other hand, the first-mentioned route has not been open for a considerable time, on account of wars that have been going on.
It is twelve years since I have had any news of the papal court, or of our order, or of the state of affairs generally in the West. Two years ago indeed there came hither a certain Lombard . . . surgeon, who spread abroad in these parts the most incredible blasphemies about the court of Rome and our order and the state of things in the West, and on this account I exceedingly desire to obtain true intelligence. I pray the brethren whom this letter may reach to do their possible to bring its contents to the knowledge of our lord the pope and the cardinals, and the agents of the order at the court of Rome . . .
I have myself grown old and gray, more with toil and trouble than with years; for I am not more than fifty-eight. I have got a competent knowledge of the language and character which is most generally used by the Tatars. And I have already translated into that language and character the New Testament and the Psalter, and have caused them to be written out in the fairest penmanship they have; and so by writing, reading, and preaching, I bear open and public testimony to the Law of Christ. And I had been in treaty with the late King George, if he had lived, to translate the whole Latin ritual, that it might be sung throughout the whole extent of his territory; and while he was alive I used to celebrate mass in his church, according to the Latin ritual, reading in the before-mentioned language and character the words of both the preface and the canon.
And the son of the king before-mentioned is called after my name, John; and I hope in God that he will walk in his father's steps.
As far as I ever saw or heard tell, I do not believe that any king or prince in the world can be compared to his majesty the khan in respect of the extent of his dominions, the vastness of their population, or the amount of his wealth. Here I stop.
Dated at the city of Khanbaliq in the kingdom of Cathay, in the year of the Lord 1305, and on the 8th day of January.
