This Carpini, or Friar John, was a Franciscan who was chosen by the Pope to go to the Great Khan of the Mongol Empire, which was threatening to overrun Christendom. On 16th April 1245, Friar John left the cloister for the unknown tract of country by which he had to pass into China. By way of Bohemia he passed into Russia, and, having annexed Brother Benedict in Poland and Brother Stephen in Bohemia, together with a guide, Carpini made his way eastwards. It was mid-winter; the travellers had to ride on Tartar horses, "for they alone could find grass under the snow, or live, as animals must in Tartary, without hay or straw." Sometimes Friar John fell so ill that he had to be placed in a cart and carried through the deep snow. [Illustration: TWO EMPERORS OF TARTARY. From the Catalan map, 1375.] It was Easter 1246, just a year after their start, that Friar John and his companions began the last section of their journey beyond the Volga, and "most tearfully we set out," not knowing whether it was "for life or for death." So thin had they all become that not one of them could ride. Still they toiled on, till one July day they entered Mongolia and found the headquarters of the Great Khan about half a day's journey from Karakorum. They arrived in time to witness the enthronement of the new Khan in August. Here were crowds of ambassadors from Russia and Persia as well as from outlying parts of the growing Mongol Empire. These were laden with gifts--indeed, there were no less than five hundred crates full of silks, satins, brocades, fur, gold embroidery. Friar John and his companions had no gifts to offer save the letter from the Pope. Impressive, indeed, in the eyes of the once cloistered friar must have been this first sight of Eastern splendour. High on a neighbouring hill stood the Khan's tent, resting on pillars plated with gold, top and sides covered with silk brocades, while the great ceremony took place. But the men of the West were not welcomed by the new Emperor of the East. It was supposed that he intended shortly to unfurl his Standard against the whole of the Western world, and in November Friar John and his companions found themselves formally dismissed with a missive from the Great Khan to the Pope, signed and sealed by the Khan himself.
