"'Moreover, to give you full information of all those places which you are very desirous to know about, you must understand that none but traders live and reside in all those islands, and that there is as great a number of ships and seafaring people, with merchandise, as in any other part of the world, particularly in a most noble port called Zaitun, where there are every year a hundred large ships of pepper loaded and unloaded, besides many other ships that take in other spices. This country is mighty populous, and there are many provinces and kingdoms, and innumerable cities, under the dominion of _a prince called the Grand Khan_, which name signifies king of kings, who for the most part resides in the province of Cathay. His predecessors were very desirous to have commerce and be in amity with Christians, and two hundred years since sent ambassadors to the Pope, desiring him to send them many learned men and doctors, to teach them our faith; but by reason of some obstacles the ambassadors met with they returned back, without coming to Rome. Besides, there came an ambassador to Pope Eugenius IV., who told him of the great friendship there was between those princes and their people, and the Christians. _I discoursed with him a long while_ upon the several matters of the grandeur of their royal structures, and of the greatness, length, and breadth of their rivers, and he told me many wonderful things of the multitude of towns and cities along the banks of the rivers, upon a single one of which there were two hundred cities, with marble bridges of great length and breadth, adorned with numerous pillars. "'This country deserves as well as any other to be discovered; and there may not only be great profit made there, and many things of value found, but also gold, silver, many sorts of precious stones, and spices in abundance, which are not brought into our ports. And it is certain that many wise men, philosophers, astrologers, and other persons skilled in all arts and very ingenious, govern that mighty province and command their armies. From Lisbon directly westward there are in the chart twenty-six spaces, each of which contains two hundred and fifty miles, to the most noble and vast city of Quinsai, which is one hundred miles in compass--that is, thirty-five leagues. In it there are ten marble bridges. The name signifies a heavenly city, of which wonderful things are reported, as to the ingenuity of the people, the buildings, and the revenues.
