The weight of half a century of years lay upon the shoulders of Juan Ponce de Leon, the discoverer, but warm hope burned in his heart, that of winning renewed boyhood and youthful strength, for it was a magic vision that drew him to these new shores, in whose depths he felt sure the realm of enchantment lay. Somewhere amid those green copses or along those liquid streams, he had been told, a living fountain sprang up clear and sparkling from the earth, its waters of such a marvellous quality that whoever should bathe in them would feel new life coursing through his veins and the vigor of youth bounding along his limbs. It was the Fountain of Youth he sought, that fabled fountain of which men had dreamed for centuries, and which was thought to lie somewhere in eastern Asia. Might not its waters upspring in this new land, whose discovery was the great marvel of the age, and which men looked upon as the unknown east of Asia? Such was the new-comer's dream. Ponce de Leon was a soldier and cavalier of Spain in those days when Spain stood first among the nations of Europe, first in strength and enterprise and daring. Brave as the bravest, he had fought with distinguished courage against the Moors of Granada at the time when Columbus was setting out on his famous voyage over the unknown seas of the West. Drawn by the fame of the discovery of the New World, De Leon sailed with Columbus in his second voyage, and proved himself a gallant soldier in the wars for the conquest of Hispaniola, of whose eastern half he was made governor. To the eastward lay another island, the fair tropic land ever since known as Porto Rico. De Leon could see from the high hills of Hispaniola the far green shores of this island, which he invaded and finally subdued in 1509, making himself its governor. A stern oppressor of the natives, he won great wealth from his possessions here and in Hispaniola. But, like many men in his position, his heart was sore from the loss of the youthful vigor which would have enabled him to enjoy to the full his new-found wealth.
