Unknown to the ancient Romans, China was revealed to their mediæval successors by the Mongol [Page 132] conquest. In 1261 two Venetian merchants, Nicolo and Matteo Polo, made their way to Bokhara, whence, joining an embassy from India, they proceeded to Kublai's capital at Xanadu (or Shangtu) near the site of Peking. They were the first white men the Grand Khan had ever seen, and he seems to have perceived at once that, if not of superior race, they were at least more advanced in civilisation than his own people; for, besides intrusting them with letters to the Pope, he gave them a commission to bring out a hundred Europeans to instruct the Mongols in the arts and sciences of the West. In 1275 they returned to Peking without other Europeans, but accompanied by Marco Polo, the son of Nicolo. They were received with more honour than on their first visit, and the young man was appointed to several positions of trust in the service of the monarch. After a sojourn of seventeen years, the three Polos obtained permission to join the escort of a Mongol princess who was going to the court of Persia. In Persia they heard of the death of their illustrious patron, and, instead of returning to China, turned their faces homeward, arriving at Venice in 1295. Having been captured by the Genoese, Marco Polo while in prison dictated his wonderful story. At first it was looked on as a romance and caused its author to receive the sobriquet of "Messer Millione"; but its general accuracy has been fully vindicated. The chief effect of that narrative was to fire the imagination of another Italian and lead him by steering to the west to seek a short cut to the Eldorado. [Page 133] How strange the occult connection of sublunary things! The Mongol Kublai must be invoked to account for the discovery of America! The same story kindled the fancy of Coleridge, in the following exquisite fragment, which he says came to him in a vision of the night: "In Xanadu did Kubla Khan A stately pleasure-dome decree: Where Alph, the sacred river, ran Through caverns measureless to man, Down to a sunless sea." --_Kubla Khan._ Still another Italian claims mention as having made some impression on the court of Kublai. This was Corvino, a missionary sent by the Pope; but of his church, his schools, and his convents, there were left no more traces than of his predecessors, the Nestorians. The glory of Kublai was not of long duration. The hardy tribes of the north became enervated by the luxury and ease of their rich patrimony. "Capua captured Hannibal." Nine of the founder's descendants followed him, not one of whom displayed either vigour or statesmanship.
