Such a reception of his stories was no great encouragement to Marco to tell the tale of his remarkable travels, but in the year of his arrival at Venice a war broke out between Genoa and the Queen of the Adriatic, in which Marco Polo was captured and cast into prison at Genoa. There he found as a fellow-prisoner one Rusticano of Pisa, a man of some learning and a sort of predecessor of Sir Thomas Malory, since he had devoted much time to re-writing, in prose, abstracts of the many romances relating to the Round Table. These he wrote, not in Italian (which can scarcely be said to have existed for literary purposes in those days), but in French, the common language of chivalry throughout Western Europe. While in prison with Marco Polo, he took down in French the narrative of the great traveller, and thus preserved it for all time. Marco Polo was released in 1299, and returned to Venice, where he died some time after 9th January 1334, the date of his will.

Of the travels thus detailed in Marco Polo's book, and of their importance and significance in the history of geographical discovery, it is impossible to give any adequate account in this place. It will, perhaps, suffice if we give the summary of his claims made out by Colonel Sir Henry Yule, whose edition of his travels is one of the great monuments of English learning:—

"He was the first traveller to trace a route across the whole longitude of Asia, naming and describing kingdom after kingdom which he had seen with his own eyes: the deserts of Persia, the flowering plateaux and wild gorges of Badakhshan, the jade-bearing rivers of Khotan, the Mongolian Steppes, cradle of the power that had so lately threatened to swallow up Christendom, the new and brilliant court that had been established by Cambaluc; the first traveller to reveal China in all its wealth and vastness, its mighty rivers, its huge cities, its rich manufactures, its swarming population, the inconceivably vast fleets that quickened its seas and its inland waters; to tell us of the nations on its borders, with all their eccentricities of manners and worship; of Tibet, with its sordid devotees; of Burma, with its golden pagodas and their tinkling crowns; of Laos, of Siam, of Cochin China, of Japan, the Eastern Thule, with its rosy pearls and golden-roofed palaces; the first to speak of that museum of beauty and wonder, still so imperfectly ransacked, the Indian Archipelago, source of those aromatics then so highly prized, and whose origin was so dark; of Java, the pearl of islands; of Sumatra, with its many kings, its strange costly products, and its cannibal races; of the naked savages of Nicobar and Andaman; of Ceylon, the island of gems, with its sacred mountain, and its tomb of Adam; of India the Great, not as a dreamland of Alexandrian fables, but as a country seen and personally explored, with its virtuous Brahmans, its obscene ascetics, its diamonds, and the strange tales of their acquisition, its sea-beds of pearl, and its powerful sun: the first in mediæval times to give any distinct account of the secluded Christian empire of Abyssinia, and the semi-Christian island of Socotra; to speak, though indeed dimly, of Zanzibar, with its negroes and its ivory, and of the vast and distant Madagascar, bordering on the dark ocean of the South, with its Ruc and other monstrosities, and, in a remotely opposite region, of Siberia and the Arctic Ocean, of dog-sledges, white bears, and reindeer-riding Tunguses."

Marco Polo's is thus one of the greatest names in the history of geography; it may, indeed, be doubted whether any other traveller has ever added so extensively to our detailed knowledge of the earth's surface. Certainly up to the time of Mr. Stanley no man had on land visited so many places previously unknown to civilised Europe. But the lands he discovered, though already fully populated, were soon to fall into disorder, and to be closed to any civilising

Extensive as were Marco Polo's travels, they were yet exceeded in extent, though not in variety, by those of the greatest of Arabian travellers, Mohammed Ibn Batuta, a native of Tangier, who began his travels in 1334, as part of the ordinary duty of a good Mohammedan to visit the holy city of Mecca. While at Alexandria he met a learned sage named Borhan Eddin, to whom he expressed his desire to travel. Borhan said to him, "You must then visit my brother Farid Iddin and my brother Rokn Eddin in Scindia, and my brother Borhan Eddin in China. When you see them, present my compliments to them." Owing mainly to the fact that the Tatar princes had adopted Islamism instead of Christianity, after the failure of Gregory X. to send Christian teachers to China, Ibn Batuta was ultimately enabled to greet all three brothers of Borhan Eddin. Indeed, he performed a more extraordinary exploit, for he was enabled to convey the greetings of the Sheikh Kawan Eddin, whom he met in China, to a relative of his residing in the Soudan. During the thirty years of his travels he visited the Holy Land, Armenia, the Crimea, Constantinople (which he visited in company with a Greek princess, who married one of the Tatar Khans), Bokhara, Afghanistan, and Delhi. Here he found favour with the emperor Mohammed Inghlak, who appointed him a judge, and sent him on an embassy to China, at first overland, but, as this was found too dangerous a route, he went ultimately from Calicut, via Ceylon, the Maldives, and Sumatra, to Zaitun, then the great port of China. Civil war having broken out, he returned by the same route to Calicut, but dared not face the emperor, and went on to Ormuz and Mecca, and returned to Tangier in 1349. But even then his taste for travel had not been exhausted. He soon set out for Spain, and worked his way through Morocco, across the Sahara, to the Soudan. He travelled along the Niger (which he took for the Nile), and visited Timbuctoo. He ultimately returned to Fez in 1353, twenty-eight years after he had set out on his travels. Their chief interest is in showing the wide extent of Islam in his day, and the facilities which a common creed gave for extensive travel. But the account of his journeys was written in Arabic, and had no influence on European knowledge, which, indeed, had little to learn from him after Marco Polo, except with regard to the Soudan. With him the history of mediæval geography may be fairly said to end, for within eighty years of his death began the activity of Prince Henry the Navigator, with whom the modern epoch begins.

Meanwhile India had become somewhat better known, chiefly by the travels of wandering friars, who visited it mainly for the sake of the shrine of St. Thomas, who was supposed to have been martyred in India. Mention should also be made of the early spread of the Nestorian Church throughout Central Asia. As early as the seventh century the Syrian Christians who followed the views of Nestorius began spreading them eastward, founding sees in Persia and Turkestan, and ultimately spreading as far as Pekin. There was a certain revival of their missionary activity under the Mongol Khans, but the restricted nature of the language in which their reports were written prevented them from having any effect upon geographical knowledge, except in one particular, which is of some interest. The fate of the Lost Ten Tribes of Israel has always excited interest, and a legend arose that they had been converted to Christianity, and existed somewhere in the East under a king who was also a priest, and known as Prester John. Now, in the reports brought by some of the Nestorian priests westward, it was stated that one of the Mongol princes named Ung Khan had adopted Christianity, and as this in Syriac sounded something like "John the Cohen," or "Priest," he was identified with the Prester John of legend, and for a long time one of the objects of travel in the East was to discover this Christian kingdom. It was, however, later ascertained that there did exist such a Christian kingdom in Abyssinia, and as owing to the erroneous views of Ptolemy, followed by the Arabs, Abyssinia was considered to spread towards Farther India, the land of Prester John was identified in Abyssinia. We shall see later on how this error helped the progress of geographical discovery.

The total addition of these mediæval travels to geographical knowledge consisted mainly in the addition of a wider extent of land in China, and the archipelago of Japan, or Cipangu, to the map of the world. The accompanying map displays the various travels and voyages of importance, and will enable the reader to understand how students of geography, who added on to Ptolemy's estimate of the extent of the world east and west the new knowledge acquired by Marco Polo, would still further decrease the distance westward between Europe and Cipangu, and thus prepare men for the voyage of Columbus.
