Christopher Columbus must have imagined himself now at the end of all his troubles. Ferdinand and Isabella received his project favourably, and caused it to be submitted for examination to a council of learned men, consisting of bishops and monks who were gathered together _ad hoc_ in a Dominican convent at Salamanca. But the unfortunate pleader was not yet at the end of his vicissitudes. In this meeting at Salamanca all his judges were against him. The truth was, that his ideas interfered with the intolerant religious notions of the fifteenth century. The Fathers of the Church had denied the sphericity of the earth, and since the earth was not round they declared that a voyage of circumnavigation was absolutely contrary to the Bible, and could not therefore, on any logical theory, be undertaken. "Besides," said these theologians, "if any one should ever succeed in descending into the other hemisphere, how could he ever mount up again into this one?" This manner of arguing was a very formidable one at this period; for Christopher Columbus saw himself, in consequence, almost accused of heresy, the most unpardonable crime which could be committed in these intolerant countries. He escaped any evil consequences from the hostile disposition of the Council, but the execution of his project was again adjourned. [Illustration: Building a caravel.] Long years passed away. The unfortunate man of genius, despairing of success in Spain, sent his brother to England to make an offer of his services to the king, Henry VII. But it is probable that the king gave no answer. Then Christopher Columbus turned again with unabated perseverance to Ferdinand, but Ferdinand was at this time engaged in a war of extermination against the Moors, and it was not until 1492, when he had chased the Moors from Spain, that he was able again to listen to the solicitations of the Genoese sailor. This time the affair was thoroughly considered, and the king consented to the enterprise. But Columbus, as is the manner of proud natures, wished to impose his own conditions. They bargained over that which should enrich Spain! Columbus, in disgust, was without doubt ready to quit, and for ever, this ungrateful country, but Isabella, touched by the thought of the unbelievers of Asia, whom she hoped to convert to the Catholic faith, ordered Columbus to be recalled, and then acceded to all his demands.
