Not far from the church of Santiago is the convent of Nuestra Señora de la Gracia on the very edge of the hill, inhabited by Augustinian nuns. The church stands on the site of an ancient mosque. The entrance is shaded by a portico with granite pillars. Our guide rang the bell at the convent door, saying: “_Ave Maria Purissima!_” “_Sin peccado concebida_,” responded a mysterious voice within, as from an oracle. St. Teresa attended school here, and several memorials of her are shown by the nuns. St. Thomas of Villanueva, the Almsgiver, who is said to have made his vows as an Augustinian friar the very day Luther publicly threw off the habit of the order, was for a time the director of the house, and often preached in the church, which we visited. It consists of a single aisle, narrow and lofty, with the gilt retable over the altar, as in all the Spanish churches, and a tomb or two of some Castilian noblemen at the side. The pulpit, in which saints have preached, is a mere circular rail against the wall, ascended by steps. When used it is hung with drapery. On the same side of the church is a picture of the young Teresa beside her teacher, Maria Briceño, a nun of fervent piety, to whom the saint said she was indebted for her first spiritual light. This nun, who, it appears, conversed admirably on religious subjects, told her pupil one day how in her youth she was so struck on reading the words of the Gospel, “Many are called, but few are chosen,” that she resolved to embrace the monastic life; and she dwelt on the rewards reserved for those who abandon all things for the love of Christ――a lesson not lost on the eager listener. At the end of the church is a large grating, through which we looked into the choir of the nuns, quiet and prayerful, with its books and pictures and stalls. Two nuns, with sweet, contemplative faces, were at prayer, dressed in queer pointed hoods and white mantles over black habits. At the sides of the communion wicket stood the angel of the Annunciation and Raphael with his fish――gilded statues of symbolic import.
