The fortunes of Columbus were now at a low ebb. He had exhausted his private means, and was in actual destitution. Downcast and disappointed, often begging his food from door to door, he made his way on foot from Genoa to the Court of Spain. Leading his little son by the hand, he one day approached the Spanish capital, and asked for bread and water at a convent door. The prior saw him, talked with him, became interested in him and his schemes, and offered to introduce him at Court. Thus Columbus obtained an interview with Cardinal Mendoza, the chief minister and confidential adviser of the King and Queen, Ferdinand and Isabella. The Cardinal was a man of extensive information and liberal mind, who perceived at once the value of Columbus’s theories and commended them to the sovereigns. The King, also, was apparently a good judge of men, and appreciated the character and ability of Columbus. But he was not willing to embark hastily in so great an enterprise as that proposed. He first called together a council of all the most learned astronomers and geographers in his kingdom, and to them referred Columbus, with his maps and charts and theories. This council met at Salamanca. It was entirely composed of friars, priests, and monks, who monopolized all the learning, both secular and religious, of that age. Some were men of large and philosophic minds; others, narrow bigots; but all were imbued with the notion that geographical discovery had reached its limits long before. In the presence of this learned body, Columbus, a simple seaman, strong in nothing save the energy of his convictions and the fire of his enthusiasm, had to appear to defend a scheme which to them must have appeared the dream of a madman. The difficulties of his position may be guessed from the nature of some of the objections made to his undertaking. His mathematical propositions and demonstrations were met with quotations from the Book of Genesis, the Psalms, the Prophets, the Epistles, the Gospels, and half a dozen of the Fathers of the Church. When he argued that the earth was spherical, his opponents quoted one of the Psalms, where the heavens are said to be extended like a hide. Some members of the council, for the sake of argument, would admit the rotundity of the earth, but denied the possibility of circumnavigating it, first, because of the intolerable heat of the torrid zone, and second, because it would take at least three years to accomplish the voyage, in which time the explorers would die of hunger, it being impossible to carry provisions sufficient for so long a time. Still others said that if a ship did reach India, she could never return, for the roundness of the globe would place a hill in her way, up which the strongest wind could not blow her.
