THE AGE OF EXPLORATION
[Sidenote: Desire of Spaniards and Portuguese for New Trade-Routes]
In the unprecedented commercial prosperity which marked the fifteenth century, two European peoples—the Portuguese and the Spanish—had little part. For purposes of general Continental trade they were not so conveniently situated as the peoples of Germany and the Netherlands; and the Venetians and other Italians had shut them off from direct trade with Asia. Yet Spanish and Portuguese had developed much the same taste for Oriental spices and wares as had the inhabitants of central Europe, and they begrudged the exorbitant prices which they were compelled to pay to Italian merchants. Moreover, their centuries-long crusades against Mohammedans in the Iberian peninsula and in northern Africa had bred in them a stern and zealous Christianity which urged them on to undertake missionary enterprises in distant pagan lands. This missionary spirit reënforced the desire they already entertained of finding new trade-routes to Asia untrammeled by rival and selfish Italians. In view of these circumstances it is not surprising that Spaniards and Portuguese sought eagerly in the fifteenth century to find new trade-routes to "the Indies."
[Sidenote: Geographical Knowledge]
In their search for new trade-routes to the lands of silk and spice, these peoples of southwestern Europe were not as much in the dark as sometimes we are inclined to believe. Geographical knowledge, almost non-existent in the earlier middle ages, had been enriched by the Franciscan friars who had traversed central Asia to the court of the Mongol emperor as early as 1245, and by such merchants and travelers as Marco Polo, who had been attached to the court of Kublai Khan and who subsequently had described that potentate's realms and the wealth of "Cipangu" (Japan). These travels afforded at once information about Asia and enormous incentive to later explorers.
Popular notions that the waters of the tropics boiled, that demons and monsters awaited explorers to the westward, and that the earth was a great flat disk, did not pass current among well-informed geographers. Especially since the revival of Ptolemy's works in the fifteenth century, learned men asserted that the earth was spherical in shape, and they even calculated its circumference, erring only by two or three thousand miles. It was maintained repeatedly that the Indies formed the western boundary of the Atlantic Ocean, and that consequently they might be reached by sailing due west, as well as by traveling eastward; but at the same time it was believed that shorter routes might be found northeast of Europe, or southward around Africa.
[Sidenote: Navigation]
Along with this general knowledge of the situation of continents, the sailors of the fifteenth century had learned a good deal about navigation. The compass had been used first by Italian navigators in the thirteenth century, mounted on the compass card in the fourteenth. Latitude was determined with the aid of the astrolabe, a device for measuring the elevation of the pole star above the horizon. With maps and accurate sailing directions (portolani), seamen could lose sight of land and still feel confident of their whereabouts. Yet it undoubtedly took courage for the explorers of the fifteenth century to steer their frail sailing vessels either down the unexplored African coast or across the uncharted Atlantic Ocean.
[Sidenote: The Portuguese Explorers]
In the series of world-discoveries which brought about the Commercial Revolution and which are often taken as the beginning of "modern history," there is no name more illustrious than that of a Portuguese prince of the blood,—Prince Henry, the Navigator (1394-1460), who, with the support of two successive Portuguese kings, made the first systematic attempts to convert the theories of geographers into proved fact. A variety of motives were his: the stern zeal of the crusader against the infidel; the ardent proselyting spirit which already had sent Franciscan monks into the heart of Asia; the hope of reëstablishing intercourse with "Prester John's" fabled Christian empire of the East; the love of exploration; and a desire to gain for Portugal a share of the Eastern trade.
To his naval training-station at Sagres and the neighboring port of Lagos, Prince Henry attracted the most skillful Italian navigators and the most learned geographers of the day. The expeditions which he sent out year after year rediscovered and colonized the Madeira and Azores Islands, and crept further and further down the unknown coast of the Dark Continent. When in the year 1445, a quarter of a century after the initial efforts of Prince Henry, Denis Diaz reached Cape Verde, he thought that the turning point was at hand; but four more weary decades were to elapse before Bartholomew Diaz, in 1488, attained the southernmost point of the African coast. What he then called the Cape of Storms, King John II of Portugal in a more optimistic vein rechristened the Cape of Good Hope. Following in the wake of Diaz, Vasco da Gama rounded the Cape in 1497, and then, continuing on his own way, he sailed up the east coast to Malindi, where he found a pilot able to guide his course eastward through the Indian Ocean to India. At Calicut Vasco da Gama landed in May, 1498, and there he erected a marble pillar as a monument of his discovery of a new route to the Indies.
[Sidenote: Occupation of Old Trade-Routes by the Turks]
While the Portuguese were discovering this new and all-water route to the Indies, the more ancient Mediterranean and overland routes, which had been of inestimable value to the Italians, were in process of occupation by the Routes by Ottoman Turks. [Footnote: Professor A. H. Lybyer has recently and ably contended that, contrary to a view which has often prevailed, the occupation of the medieval trade-routes by the Ottoman Turks was not the cause of the Portuguese and Spanish explorations which ushered in the Commercial Revolution. He has pointed out that prior to 1500 the prices of spices were not generally raised throughout western Europe, and that apparently before that date the Turks had not seriously increased the difficulties of Oriental trade. In confirmation of this opinion, it should be remembered that the Portuguese had begun their epochal explorations long before 1500 and that Christopher Columbus had already returned from "the Indies.">[ These Turks, as we have seen, were a nomadic and warlike nation of the Mohammedan faith who "added to the Moslem contempt for the Christian, the warrior's contempt for the mere merchant." Realizing that advantageous trade relations with such a people were next to impossible, the Italian merchants viewed with consternation the advance of the Turkish armies, as Asia Minor, Thrace, Macedonia, Greece, and the islands of the Ægean were rapidly overrun. Constantinople, the heart of the Eastern Empire, repeatedly repelled the Moslems, but in 1453 Emperor Constantine XI was defeated by Sultan Mohammed II, and the crescent replaced the Greek cross above the Church of Saint Sophia. Eight years later Trebizond, the terminal of the trade-route from Tabriz, was taken. In vain Venice attempted to defend her possessions in the Black Sea and in the Ægean; by the year 1500 most of her empire in the Levant was lost. The Turks, now in complete control of the northern route, proceeded to impose crushing burdens on the trade of the defeated Venetians. Florentines and other Italians who fared less hardly continued to frequent the Black Sea, but the entire trade suffered from Turkish exactions and from disturbing wars between the Turks and another Asiatic people—the Mongols.
[Sidenote: Loss to the Italians]
For some time the central and southern routes, terminating respectively in Syria and Egypt, exhibited increased activity, and by rich profits in Alexandria the Venetians were able to retrieve their losses in the Black Sea. But it was only a matter of time before the Turks, conquering Damascus in 1516 and Cairo in 1517, extended their burdensome restrictions and taxes over those regions likewise. Eastern luxuries, transported by caravan and caravel over thousands of miles, had been expensive and rare enough before; now the added peril of travel and the exactions of the Turks bade fair to deprive the Italians of the greater part of their Oriental trade. It was at this very moment that the Portuguese opened up independent routes to the East, lowered the prices of Asiatic commodities, and grasped the scepter of maritime and commercial power which was gradually slipping from the hands of the Venetians. The misfortune of Venice was the real opportunity of Portugal.
[Sidenote: Columbus]
Meanwhile Spain had entered the field, and was meeting with cruel disappointment. A decade before Vasco da Gama's famous voyage, an Italian navigator, Christopher Columbus, had presented himself at the Spanish court with a scheme for sailing westward to the Indies. The Portuguese king, by whom Columbus formerly had been employed, already had refused to support the project, but after several vexatious rebuffs Columbus finally secured the aid of Ferdinand and Isabella, the Spanish monarchs who were at the time jubilant over their capture of Granada from the Mohammedans (January, 1492). In August, 1492, he sailed from Palos with 100 men in three small ships, the largest of which weighed only a hundred tons. After a tiresome voyage he landed (12 October, 1492) on "San Salvador," one of the Bahama Islands. In that bold voyage across the trackless Atlantic lay the greatness of Columbus. He was not attempting to prove a theory that the earth was spherical—that was accepted generally by the well informed. Nor was he in search of a new continent. The realization that he had discovered not Asia, but a new world, would have been his bitterest disappointment. He was seeking merely another route to the spices and treasures of the East; and he bore with him a royal letter of introduction to the great Khan of Cathay (China). In his quest he failed, even though he returned in 1493, in 1498, and finally in 1502 and explored successively the Caribbean Sea, the coast of Venezuela, and Central America in a vain search for the island "Cipangu" and the realms of the "Great Khan." He found only "lands of vanity and delusion as the miserable graves of Castilian gentlemen," and he died ignorant of the magnitude of his real achievement.
[Sidenote: America]
Had Columbus perished in mid ocean, it is doubtful whether America would have remained long undiscovered. In 1497 John Cabot, an Italian in the service of Henry VII of England, reached the Canadian coast probably near Cape Breton Island. In 1500 Cabral with a Portuguese expedition bound for India was so far driven out of his course by equatorial currents that he came upon Brazil, which he claimed for the king of Portugal. Yet America was named for neither Columbus, Cabot, nor Cabral, but for another Italian, the Florentine Amerigo Vespucci, who, returning from voyages to Brazil (1499-1500), published a letter concerning what he called "the new world." It was thought that he had discovered this new world, and so it was called after him,—America.
[Sidenote: First Circumnavigation of the Earth]
Very slowly the truth about America was borne in upon the people of Europe. They persisted in calling the newly discovered lands the "Indies," and even after Balboa had discovered (1513) that another ocean lay beyond the Isthmus of Panama, it was thought that a few days' sail would bring one to the outlying possessions of the Great Khan. Not until Magellan, leaving Spain in 1519, passed through the straits that still bear his name and crossed the Pacific was this vain hope relinquished. Magellan was killed by the natives of the Philippine Islands, but one of his ships reached Seville in 1522 with the tale of the marvelous voyage.
Even after the circumnavigation of the world explorers looked for channels leading through or around the Americas. Such were the attempts of Verrazano (1524), Cartier (1534), Frobisher (1576-1578), Davis (1585-1587), and Henry Hudson in 1609.
