Some days were given by the Spaniards to festivity, in which they were successively entertained at the hospitable boards of the four great nobles, in their several quarters of the city. Amidst these friendly demonstrations, however, the general never relaxed for a moment his habitual vigilance, or the strict discipline of the camp; and he was careful to provide for the security of the citizens by prohibiting, under severe penalties, any soldier from leaving his quarters without express permission. Indeed, the severity of his discipline provoked the remonstrance of more than one of his officers, as a superfluous caution; and the Tlascalan chiefs took some exception at it, as inferring an unreasonable distrust of them. But, when Cortés explained it, as in obedience to an established military system, they testified their admiration, and the ambitious young general of the republic proposed to introduce it, if possible, into his own ranks.[177] The Spanish commander, having assured himself of the loyalty of his new allies, next proposed to accomplish one of the great objects of his mission, their conversion to Christianity. By the advice of Father Olmedo, always opposed to precipitate measures, he had deferred this till a suitable opportunity presented itself for opening the subject. Such a one occurred when the chiefs of the state proposed to strengthen the alliance with the Spaniards by the intermarriage of their daughters with Cortés and his officers. He told them this could not be while they continued in the darkness of infidelity. Then, with the aid of the good friar, he expounded as well as he could the doctrines of the Faith, and, exhibiting the image of the Virgin with the infant Redeemer, told them that there was the God in whose worship alone they would find salvation, while that of their own false idols would sink them in eternal perdition. It is unnecessary to burden the reader with a recapitulation of his homily, which contained, probably, dogmas quite as incomprehensible to the untutored Indian as any to be found in his own rude mythology. But, though it failed to convince his audience, they listened with a deferential awe. When he had finished, they replied they had no doubt that the God of the Christians must be a good and a great God, and as such they were willing to give him a place among the divinities of Tlascala. The polytheistic system of the Indians, like that of the ancient Greeks, was of that accommodating kind which could admit within its elastic folds the deities of any other religion, without violence to itself.[178] But every nation, they continued, must have its own appropriate and tutelary deities. Nor could they, in their old age, abjure the service of those who had watched over them from youth. It would bring down the vengeance of their gods, and of their own nation, who were as warmly attached to their religion as their liberties, and would defend both with the last drop of their blood!
