Columbus carefully gathered all these facts, pondered over them day and night, and, after comparing with them such information as he found in old as well as contemporary authors, became thoroughly convinced that his theories were correct. He remembered, however, that “to err is human” and that four eyes are better than two. Thinking it unwise to rely upon his own opinions alone, he consulted a man whose learning and wisdom made his advice of the highest value. This was Toscanelli, a Florentine physician, born in 1397. He was very old at this time, but he had already declared his belief to Alfonso the Fifth that a voyage across the Atlantic Ocean to the East Indies was perfectly practical, and had sent a chart to Lisbon upon which the distance and choice of routes was traced. Toscanelli approved the scheme of Columbus and not only gave him much valuable advice but urged him to put his plans in operation as soon as possible. Columbus was now fully determined to set about his work but he needed assistance in his preparations. Some government must help him and to which one should he give the preference? He promptly decided that his own dear fatherland should participate in the honor of his discoveries. He submitted his scheme to the Genoese Council and asked for the necessary assistance. The Council, however, attached no importance to it, regarded him as an inexperienced man, and rejected his proposals. He was discouraged by its decision but, feeling that he had at least performed his duty to his fatherland, he went to Lisbon to submit his plans to the Court, which at this time was more friendly to expeditions than any other. He waited upon King John the Second and asked permission of him and his Council to carry out the scheme upon which he had been engaged so many years. His proposition was favorably considered but subsequently his plan was stolen little by little and he found himself the victim of most despicable treachery. The Portuguese hastily fitted up a vessel and placed it in command of another leader, who sailed away on Columbus’ course; but he had neither the latter’s skill nor courage and, after a short western voyage, abandoned the undertaking as hopeless and returned to Lisbon. Indignant at such treachery, Columbus forsook a Court which had treated him so meanly and went with his son, Diego, to Madrid. As his wife had died some time before this he never returned to Lisbon. Fearing possibly that his scheme might not be accepted at the Spanish Court, he sent his brother Bartolomeo, who was familiar with all the details of his plan, to England, to ascertain whether he could expect help in that quarter.
