Early in the morning a Moorish cavalier with an escort approached the advance guard, and his trumpets sounded a parley. He craved an audience as an envoy from El Zagal, and was admitted to the tent of Don Fadrique. El Zagal had learnt that the Christian troops had come to aid his nephew, and now offered to enter into an alliance with them on terms still more advantageous than those of Boabdil. The wary Don Fadrique listened to the Moor with apparent complacency, but determined to send one of his most intrepid and discreet cavaliers, under the protection of a flag, to hold a conference with the old king within the very walls of the Alhambra. The officer chosen for this important mission was Don Juan de Vera, the same stanch and devout cavalier who in times preceding the war had borne the message from the Castilian sovereigns to old Muley Abul Hassan demanding arrears of tribute. Don Juan was received with great ceremony by the king. No records remain of his diplomatic negotiations, but they extended into the night, and, it being too late to return to camp, he was sumptuously lodged in an apartment of the Alhambra. In the morning one of the courtiers about the palace, somewhat given to jest and raillery, invited Don Juan to a ceremony which some of the alfaquis were about to celebrate in the mosque of the palace. The religious punctilio of this most discreet cavalier immediately took umbrage at what he conceived a banter. “The servants of Queen Isabella of Castile,” replied he, stiffly and sternly, “who bear on their armor the cross of St. Jago, never enter the temples of Mahomet but to level them to the earth and trample on them.”
