COLUMBUS A THEORETICAL CIRCUMNAVIGATOR. JOHN CLARK RIDPATH, LL. D., an American author and educator. Born in Putnam County, Indiana, April 26, 1840. From "History of United States," 1874. Sir John Mandeville had declared in the very first English book that ever was written (A. D. 1356) that the world is a sphere, and that it was both possible and practicable for a man to sail around the world and return to the place of starting; but neither Sir John himself nor any other seaman of his times was bold enough to undertake so hazardous an enterprise. Columbus was, no doubt, the first _practical_ believer in the theory of circumnavigation, and although he never sailed around the world himself, he demonstrated the possibility of doing so. The great mistake with Columbus and others who shared his opinions was not concerning the figure of the earth, but in regard to its size. He believed the world to be no more than 10,000 or 12,000 miles in circumference. He therefore confidently expected that after sailing about 3,000 miles to the westward he should arrive at the East Indies, and to do that was the one great purpose of his life.
