The expeditions sent out by Prince Henry began by rediscovering the Madeira and Azores Islands, first visited by Europeans in the fourteenth century. Then the Portuguese turned southward along the unchartered African coast. In 1445 A.D. they got as far as Cape Verde, or "Green Cape," so called because of its luxuriant vegetation. The discovery was important, for it disposed of the idea that the Sahara desert extended indefinitely to the south. Sierra Leone, which the Carthaginian Hanno [11] had probably visited, was reached in 1462 A.D., two years after Prince Henry's death. Soon Portuguese sailors found the great bend of the African coast formed by the gulf of Guinea. In 1471 A.D. they crossed the equator, without the scorching that some had feared. In 1482 A.D. they were at the mouth of the Congo. Six years later Bartholomew Diaz rounded the southern extremity of Africa. The story goes that he named it the Cape of Storms, and that the king of Portugal, recognizing its importance as a stage on the route to the East, rechristened it the Cape of Good Hope.
DA GAMA'S VOYAGE, 1497-1499 A.D.
A daring mariner, Vasco da Gama, opened the sea-gates to the Indies. With four tiny ships he set sail from Lisbon in July, 1497 A.D., and after leaving the Cape Verde Islands made a wide sweep into the South Atlantic. Five months passed before Africa was seen again. Having doubled the Cape of Good Hope in safety, Da Gama skirted the eastern shores of Africa and at length secured the services of a Moslem pilot to guide him across the Indian Ocean. In May, 1498 A.D., he reached Calicut, [12] an important commercial city on the southwest coast of India. When Da Gama returned to Lisbon, after an absence of over two years, he brought back a cargo which repaid sixty times the cost of the expedition. The Portuguese king received him with high honor and created him Admiral of the Indies.

CAMOENS, 1524-1580 A.D., AND THE LUSIADS
The story of Da Gama's memorable voyage was sung by the Portuguese poet, Camoens, in the Lusiads. It is the most successful of all modern epics. The popularity of the Lusiads has done much to keep alive the sense of nationality among the Portuguese, and even to-day it forms a bond of union between Portugal and her daughter-nation across the Atlantic—Brazil.
SIGNIFICANCE OF THE MARITIME ROUTE
The discovery of an ocean passage to the East came at the right moment. Just at this time the Ottoman Turks were beginning to block up the old trade routes. [13] Their conquests in Asia Minor and southeastern Europe, during the fifteenth century, shut out the Italians from the northern route through the Aegean and the Black Sea. After Syria and Egypt were conquered, early in the sixteenth century, the central and southern routes also passed under Turkish control. The Ottoman advance struck a mortal blow at the prosperity of the Italian cities, which had so long monopolized Oriental trade. But the misfortune of Venice and Genoa was the opportunity of Portugal.
