In the eleventh century King Alfonso, at the insistence of Bernard and Constance, and the papal legate Richard, decided to abolish the use of the old Gothic ritual and to introduce the Gregorian rite. The Toledans threatened revolt rather than abandon their old form of worship. The King knew no other method of decision than to leave the question to two champions. In single combat the Knight of the Gothic Missal, Don Juan Ruiz de Mantanzas, killed his adversary while he himself remained unhurt. At a second trial, where two bulls were entrusted with the perplexing difficulty, the Gothic bull came off victor. Councils were held and the Pope still persevered in his determination to abolish the old Spanish service book. Outside the walls of the city, in front of the King and churchmen and amid the entire populace of Toledo, a great fire was built, and the two mass-books were thrown into it. When the flames had died down, only the Gothic mass-book was found unscathed. Only after many years, when traditions had gradually altered and even much of the text had become meaningless to the clergy, did the Roman service book become universally introduced into Toledan houses of worship. Two other chapels are of especial interest: those of Saint Ildefonso and Santiago. Saint Ildefonso, who became metropolitan in 658, is second only in honor to Saint James of Compostella; he was unquestionably the most favored of Toledo's long line of bishops. Three natives of Narbonne had dared to question the perpetual virginity of Our Lady. Saint Ildefonso gallantly took up her defense and proved it beyond doubt or questioning in his treatise "De Virginitate Perpetua Sanctae Mariae adversus tres Infideles." It was a crushing vindication and a discourse of much reason and scriptural light. Shortly afterwards the Bishop, together with the King and court, went to the Church of Saint Leocadia to give public thanks. As soon as the multitude had had sufficient time to kneel at the saint's tomb, a group of angels appeared amid a cloud and surrounded by sweet scents. Next the sepulchre opened of its own accord. Calix relates, "Thirty men could not have moved the stone which slid slowly from the mouth of the tomb. Immediately Saint Leocadia arose, after lying there three hundred years, and holding out her arm, she shook hands with Saint Ildefonso, speaking in this voice, 'Oh, Ildefonso, through thee doth the honor of My Lady flourish.' All the spectators were silent, being struck with the novelty and the greatness of the miracle. Only Saint Ildefonso, with Heaven's aid, replied to her. Now the virgin Saint looked as if she wished to return into the tomb and she turned around for that purpose, when the King begged of Saint Ildefonso that he would not let her go until she left some relic of her behind, for a memorial of the miracle and for the consolation of the city. And as Saint Ildefonso wished to cut a part of the white veil which covered the head of St.
