The prelude to the Age of Discovery, however, is to be found neither in the Norse explorations in the Atlantic nor in the Arab activities in the Indian Ocean but, rather, in the land journeys of Italian missionaries and merchants that linked the Mediterranean coasts to the China Sea. Cosmas Indicopleustes, an Alexandrian geographer writing in the 6th century, knew that Tzinitza (China) could be reached by sailing eastward, but he added: “One who comes by the overland route from Tzinitza to Persia makes a very short cut.” Goods had certainly passed this way since Roman times, but they usually changed hands at many a mart, for disorganized and often warring tribes lived along the routes. In the 13th century the political geography changed. In 1206 a Mongol chief assumed the title of Genghis Khan and, after campaigns in China that gave him control there, turned his conquering armies westward. He and his successors built up an enormous empire until, in the late 13th century, one of them, Kublai Khan, reigned supreme from the Black Sea to the Yellow Sea. Europeans of perspicacity saw the opportunities that friendship with the Mongol power might bring. If Christian Europe could only convert the Mongols, this would at one and the same time heavily tip the scales against Muslim and in favour of Christian power and also give political protection to Christian merchants along the silk routes to the legendary sources of wealth in China. With these opportunities in mind, Pope Innocent IV sent friars to “diligently search out all things that concerned the state of the Tartars” and to exhort them “to give over their bloody slaughter of mankind and to receive the Christian faith.” Among others, Giovanni da Pian del Carpini in 1245 and Willem van Ruysbroeck in 1253 went forth to follow these instructions. Traveling the great caravan routes from southern Russia, north of the Caspian and Aral seas and north of the Tien Shan (Tien Mountains), both Carpini and Ruysbroeck eventually reached the court of the emperor at Karakorum. Carpini returned confident that the emperor was about to become a Christian; Ruysbroeck told of the city in Cathay “having walls of silver and towers of gold”; he had not seen it but had been “credibly informed” of it.

But the greatest of the 13th-century travelers in Asia were the Polos, wealthy merchants of Venice. In 1260 the brothers Nicolo and Maffeo Polo set out on a trading expedition to Crimea. After two years they were ready to return to Venice, but, finding the way home blocked by war, they traveled eastward to Bukhara (now in Uzbekistan in Central Asia), where they spent another three years. The Polos then accepted an invitation to accompany a party of Tatar envoys returning to the court of Kublai Khan at Cambaluc, near Peking (Beijing). The khan received them well, provided them with a gold tablet as a safe-conduct back to Europe, and gave them a letter begging the pope to send “some hundred wise men, learned in the law of Christ and conversant with the seven arts to preach to his people.” The Polos arrived home, “having toiled three years on the way,” to find that Pope Clement IV was dead. Two years later they set off again, traveling without the wise men but taking with them Nicolo’s son, Marco Polo, then a youth of 17. (Marco kept detailed notes of all he saw and, late in life when a captive of the Genoese, dictated to a fellow prisoner a book containing an account of his travels and adventures.) This time the Polos took a different route: starting from the port of Hormuz on the Persian Gulf, they crossed Persia to the Pamirs and then followed a caravan route along the southern edge of the Tarim Basin and Gobi Desert to Cambaluc. Information about the route is interesting, but the great contribution of Marco Polo to the geographical knowledge of the West lay in his vivid descriptions of the East. He had tremendous opportunities of seeing China and appreciating its life, for he was taken into the service of the khan and was sent as an administrator to great cities, busy ports, and remote provinces, with instructions to write full reports. In his book he described how, upon every main high road, at a distance apart of 25 or 30 miles (40 to 50 km), there were stations, with houses of accommodation for travelers, with 400 good horses kept in constant readiness at each station. He also reported that, along the roads, the great khan had caused trees to be planted, both to provide shade in summer and to mark the route in winter when the ground was covered with snow. Marco Polo lived and worked in western China, visiting the provinces of Shensi (Shaanxi), Szechwan (Sichuan), and Yunnan, as well as the borders of Burma (now Myanmar). He frequently visited “the noble and magnificent city of Quinsay [Hangzhou], a name that signifies the Celestial City and which it merits from its preeminence to all others in the world in point of grandeur and beauty.” Cipango (Japan) he did not visit, but he heard about it from merchants and sailors: “It is situated at a distance of 1,500 miles from the mainland.…They have gold in the greatest abundance, its sources being inexhaustible.” The most detailed descriptions and the greatest superlatives were reserved for Cambaluc, capital of Cathay, whose splendours were beyond compare; to this city, he said,

everything that is most rare and valuable in all parts of the world finds its way: …for not fewer than 1,000 carriages and pack-horses loaded with raw silk make their daily entry; and gold tissues and silks of various kinds are manufactured to an immense extent.

No wonder that, when Europe learned of these things, it became enthralled. After 17 years, the Venetians were permitted to depart; they returned to Europe by sea. After visiting Java they sailed through the Strait of Malacca (again proving the error of Ptolemy); and, landing at Hormuz, they traveled cross-country to Armenia, and so home to Venice, which they reached in 1295.

A few travelers followed the Polos. Giovanni da Montecorvino, a Franciscan friar from Italy, became archbishop of Peking and lived in China from 1294 to 1328. Friar Oderic of Pordenone, an Italian monk, became a missionary, journeying throughout the greater part of Asia between 1316 and 1330. He reached Peking by way of India and Malaya, then traveled by sea to Canton; he returned to Europe by way of Central Asia, visiting Tibet in 1325—the first European to do so. Friar Oderic’s account of his journeys had considerable influence in his day: it was from it that the spurious traveler, the English writer Sir John Mandeville, quarried most of his stories.

Exploration and Discovery

Ibn Baṭṭūṭah, an Arab of Tangier, journeyed farther perhaps than any other medieval traveler. In 1325 he set out to make the traditional pilgrimage to Mecca, and in some 30 years he visited the greater part of the Old World, covering, it has been said, more than 75,000 miles (120,700 km). He was the first to explore much of Arabia; he traveled extensively in India; he reached Java and Southeast Asia. Then toward the end of his life he returned to the west, where, after visiting Spain, he explored western Sudan “to the northernmost province of the Negroes.” He reached the Niger, which he called the Nile, and was astonished by the huge hippopotamuses “taking them to be elephants.” When he finally returned to Fès in Morocco he “kissed the hand of the Commander of the Faithful the Sultan…and settled down under the wing of his bounty.” He wrote a vivid and perspicacious account of his travels, but his book did not become known to Christian Europe for centuries. It was Marco Polo’s book that was the most popular of all. Some 138 manuscripts of it survive: it was translated before 1500 into Latin, German, and Spanish, and the first English translation was published in 1577. For centuries Europe’s maps of the Far East were based on the information provided by Marco Polo; even as late as 1533 Johannes Schöner, the German maker of globes, wrote:

Behind the Sinae and the Ceres [legendary cities of Central Asia]…many countries were discovered by one Marco Polo…and the sea coasts of these countries have now recently again been explored by Columbus and Amerigo Vespucci in navigating the Indian Ocean.

Columbus possessed and annotated a copy of the Latin edition (1483–85) of Marco Polo’s book, and in his journal he identified many of his own discoveries with places that Marco Polo describes.

Thus, with Ptolemy in one hand and Marco Polo in the other, the European explorers of the Age of Discovery set forth to try to reach Cathay and Cipango by new ways; Ptolemy promised that the way was short, and Marco Polo promised that the reward was great.
