to the verge of the Old World, filling the harbours of the Mediterranean with ships and the monasteries of Italy and Spain with wisdom; and in the subsequent and punctual decadence that followed this flood, there gathered in the returning tide a greater energy and volume which was to carry the Old World bodily across the ocean.  And yet, for all their wisdom and power, the Spanish and Portuguese were still in the attitude of our primitive man, standing on the sea-shore and looking out in wonder across the sea.

The flood of the life-stream began to set again, and little by little to rise and inundate Western Europe, floating off the galleys and caravels of King Alphonso of Portugal, and sending them to feel their way along the coasts of Africa; a little later drawing the mind of Prince Henry the Navigator to devote his life to the conquest and possession of the unknown.  In his great castle on the promontory of Sagres, with the voice of the Atlantic thundering in his ears, and its mists and sprays bounding his vision, he felt the full force of the stream, and stretched his arms to the mysterious West.  But the inner light was not yet so brightly kindled that he dared to follow his heart; his ships went south and south again, to brave on each voyage the dangers and terrors that lay along the unknown African coast, until at length his captains saw the Cape of Good Hope.  South and West and East were in those days confusing terms; for it was the East that men were thinking of when they set their faces to the setting sun, and it was a new road to the East that they sought when they felt their way southward along the edge of the world.  But the rising tide of discovery was working in that moment, engaging the brains of innumerable sages, stirring the wonder of innumerable mariners; reaching also, little by little, to quarters less immediately concerned with the business of discovery.  Ships carried the strange tidings of new coasts and new islands from port to port throughout the Mediterranean; Venetians on the lagoons, Ligurians on the busy trading wharves of Genoa, were discussing the great subject; and as the tide rose and spread, it floated one ship of life after another that was destined for the great business of adventure.  Some it inspired to dream and speculate, and to do no more than that; many a heart also to brave efforts and determinations that were doomed to come to nothing and to end only in failure.  And among others who felt the force and was swayed and lifted by the prevailing influence, there lived, some four and a half centuries ago, a little boy playing about the wharves of Genoa, well known to his companions as Christoforo, son of Domenico the wool-weaver, who lived in the Vico Dritto di Ponticello.
