Nevertheless, in the Catalan map, made in 1375, and now to be seen in the National Library at Paris, there is a thorough-going and not unsuccessful attempt to embody the results of Polo's travels. In the interval of three quarters of a century since the publication of Marco's narrative, several adventurous travellers had found their way to Cathay. There was Friar Odoric, of Pordenone, who, during the years 1316-30 visited Hindustan, Sumatra, Java, Cochin China, the Chinese Empire, and Thibet.[335] It was from this worthy monk that the arrant old impostor, "Sir John Mandeville," stole his descriptions of India and Cathay, seasoning them with yarns from Pliny and Ktesias, and grotesque conceits of his own.[336] Several other missionary friars visited China between 1302 and 1330, and about ten years after the latter date the Florentine merchant, Francesco Pegolotti, wrote a very useful handbook for commercial travellers on the overland route to that country.[337] Between 1338 and 1353 Giovanni Marignolli spent some years at Peking, as papal legate from Benedict XI. to the Great Khan, and also travelled in Ceylon and Hindustan.[338] That seems to have been the last of these journeys to the Far East. In 1368, the people of China rose against the Mongol dynasty and overthrew it. The first emperor of the native Ming dynasty was placed upon the throne, and the Chinese retorted upon their late conquerors by overrunning vast Mongolia and making it Chinese Tartary. The barriers thrown down by the liberal policy of the Mongol sovereigns were now put up again, and no more foreigners were allowed to set foot upon the sacred soil of the Flowery Kingdom. [Footnote 335: Odoric mentions Juggernaut processions and the burning of widows; in Sumatra he observed cannibalism and community of wives; he found the kingdom of Prester John in Chinese Tartary; "but as regards him," says wise Odoric, "not one hundredth part is true of what is told of him as if it were undeniable."
