It was clearly inexpedient to press the matter further at present. But the zeal of Cortés, as usual, waxing warm by opposition, had now mounted too high for him to calculate obstacles; nor would he have shrunk, probably, from the crown of martyrdom in so good a cause. But, fortunately, at least for the success of his temporal cause, this crown was not reserved for him. The good monk, his ghostly adviser, seeing the course things were likely to take, with better judgment interposed to prevent it. He had no desire, he said, to see the same scenes acted over again as at Cempoalla. He had no relish for forced conversions. They could hardly be lasting. The growth of an hour might well die with the hour. Of what use was it to overturn the altar, if the idol remained enthroned in the heart? or to destroy the idol itself, if it were only to make room for another? Better to wait patiently the effect of time and teaching to soften the heart and open the understanding, without which there could be no assurance of a sound and permanent conviction. These rational views were enforced by the remonstrances of Alvarado, Velasquez de Leon, and those in whom Cortés placed most confidence; till, driven from his original purpose, the military polemic consented to relinquish the attempt at conversion for the present, and to refrain from a repetition of scenes which, considering the different mettle of the population, might have been attended with very different results from those at Cozumel and Cempoalla.[179] In the course of our narrative we have had occasion to witness more than once the good effects of the interposition of Father Olmedo. Indeed, it is scarcely too much to say that his discretion in spiritual matters contributed as essentially to the success of the expedition as did the sagacity and courage of Cortés in temporal. He was a true disciple in the school of Las Casas. His heart was unscathed by that fiery fanaticism which sears and hardens whatever it touches. It melted with the warm glow of Christian charity. He had come out to the New World as a missionary among the heathen, and he shrank from no sacrifice but that of the welfare of the poor benighted flock to whom he had consecrated his days. If he followed the banners of the warrior, it was to mitigate the ferocity of war, and to turn the triumphs of the Cross to a good account for the natives themselves, by the spiritual labors of conversion. He afforded the uncommon example--not to have been looked for, certainly, in a Spanish monk of the sixteenth century--of enthusiasm controlled by reason, a quickening zeal tempered by the mild spirit of toleration. But, though Cortés abandoned the ground of conversion for the present, he compelled the Tlascalans to break the fetters of the unfortunate victims reserved for sacrifice; an act of humanity unhappily only transient in its effects, since the prisons were filled with fresh victims on his departure.
