Cortes, seeing that he was much agitated, pretended that the demand had come from his followers, and that he would endeavour to persuade them to be contented with one of the sanctuaries of the teocalli. If that were not granted, they should be obliged to take it by force and to throw down the idols in the face of the city. Montezuma, still greatly disturbed, promised to confer with the priests, and in the end the Spaniards were allowed to take possession of one of the sanctuaries, in which, when it had been purified, an altar was raised, surmounted by a crucifix and the imago of the Virgin; its walls were decorated with garlands of fresh flowers, and an old soldier was stationed to watch over it. Then the whole army moved in solemn procession up the winding ascent of the pyramid, and mass was celebrated by Father Olmedo and another priest, while the Aztecs looked on with mingled curiosity and repugnance. For a nation will endure any outrage sooner than that which attacks its religion, and this profanation touched a feeling in the natives which the priests were not slow to take advantage of. Soon the Spaniards noticed a change in Montezuma. He was grave instead of cheerful, and avoided their society. Many conferences went on between him and the priests and nobles, at which even Orteguilla, his favourite page, was not allowed to be present. Presently Cortes received a summons to appear before the emperor, who told him that his predictions had come to pass, his gods were offended, and threatened to forsake the city if the sacrilegious strangers were not driven from it, or sacrificed on their altars as an expiation. 'If you have any regard for your safety,' he continued, 'you will leave the country without delay. I have only to raise my finger, and every Aztec in the land will rise against you.'
