*"The explorations of Columbus and those of his contemporaries
completely revised the world picture. As a result, cartographers
were stimulated to devise new methods for depicting the enlarged
world. But the voyages did even more: they relegated the
Mediterranean to a secondary place in world affairs by diverting
trade between Europe and the Orient to the Atlantic." *Doctors Clarence B. Odell and Dale Edward Case in: Geographical Background of the First Voyage of Columbus
