The voyage by land in search of Prester John had thus been completely successful, while, at the same time, information had been obtained giving certain hopes of the voyage by sea. This had, in its way, been almost as successful, for Diaz had rounded the cape now known as the Cape of Good Hope, but to which he proposed giving the title of Cabo Tormentoso, or "Stormy Cape." King João, however, recognising that Diaz's voyage had put the seal upon the expectations with which Prince Henry had, seventy years before, started his series of explorations, gave it the more auspicious name by which it is now known. For some reason which has not been adequately explained, no further attempt was made for nearly ten years to carry out the final consummation of Prince Henry's plan by sending out another expedition. In the meantime, as we shall see, Columbus had left Portugal, after a mean attempt had been made by the king to carry out his novel plan of reaching India without his aid; and, as a just result, the discovery of a western voyage to the Indies (as it was then thought) had been successfully accomplished by Columbus, in the service of the Catholic monarchs of Spain, in 1492. This would naturally give pause to any attempt at reaching India by the more cumbersome route of coasting along Africa, which had turned out to be a longer process than Prince Henry had thought. Three years after Columbus's discovery King João died, and his son and successor Emmanuel did not take up the traditional Portuguese method of reaching India till the third year of his reign. By this time it had become clear, from Columbus's second voyage, that there were more difficulties in the way of reaching the Indies by his method than had been thought; and the year after his return from his second voyage in 1496, King Emmanuel determined on once more taking up the older method. He commissioned Vasco da Gama, a gentleman of his court, to attempt the eastward route to India with three vessels, carrying in all about sixty men. Already by this time Columbus's bold venture into the unknown seas had encouraged similar boldness in others, and instead of coasting down the whole extent of the western coast of Africa, Da Gama steered direct for Cape Verde Islands, and thence out into the ocean, till he reached the Bay of St. Helena, a little to the north of the Cape of Good Hope.
