But now a new era was about to begin--a new age was dawning--and we open a wonderful chapter in the history of discovery, perhaps the most wonderful in all the world. In Portugal a man had arisen who was to awaken the slumbering world of travel and direct it to the high seas. And the name of this man was Henry, a son of King John of Portugal. His mother was an Englishwoman, daughter of "John of Gaunt, time-honoured Lancaster." The Prince was, therefore, a nephew of Henry IV. and great-grandson of Edward III. of England. But if English blood flowed in his veins he, too, was the son of the "greatest King that ever sat on the throne of Portugal," and at the age of twenty he had already learned something of the sea that lay between his father's kingdom and the northern coast of Africa. Thus, when in the year 1415 King John planned a great expedition across the narrow seas to Ceuta, an important Moorish city in North Africa, it fell to Prince Henry himself to equip seven triremes, six biremes, twenty-six ships of burden, and a number of small craft. These he had ready at Lisbon when news reached him that the Queen, his mother, was stricken ill. The King and three sons were soon at her bedside. It was evident that she was dying. "What wind blows so strongly against the side of the house?" she asked suddenly. "The wind blows from the north," replied her sons. "It is the wind most favourable for your departure," replied Philippa. And with these words the English Queen died. This is not the place to tell how the expedition started at once as the dead Queen had wished, how Ceuta was triumphantly taken, and how Prince Henry distinguished himself till all Europe rang with his fame. Henry V. of England begged him to come over and take command of his forces. The Emperor of Germany sent the same request. But he had other schemes for his life. He would not fight the foes of England or of Germany, rather would he fight the great ocean whose waves dashed high against the coast of Portugal. He had learned something of inland Africa, of the distant coast of Guinea, and he was fired with the idea of exploring along this west coast of Africa and possibly reaching India by sea. Let us recall what was known of the Atlantic only six centuries ago. "It was," says an old writer, "a vast and boundless ocean, on which ships dared not venture out of sight of land. For even if the sailors knew the direction of the winds they would not know whither those winds would carry them, and, as there is no inhabited country beyond, they would run great risk of being lost in mist and vapour. The limit of the West is the Atlantic Ocean." The ocean was a new and formidable foe, hitherto unconquered and unexplored. At last one had arisen to attempt its conquest. As men had lifted the veil from the unknown land of China, so now the mists were to be cleared from the Sea of Darkness.
