There are other frescoes of less importance in other parts of the Spedale. In the room on the left of the entrance is a fresco by Beccafumi, one of his early works, painted in 1512, representing the meeting of Joachim and Anne. The Infirmary of San Pietro has unimportant frescoes by Vecchietta, and (inclosed in a tabernacle) the "Madonna of Mercy," by Domenico di Bartolo. In the Infirmary of San Pio a "Beato Sorore" is likewise ascribed to Domenico, and in the Infirmary of San Galgano is a Crucifixion by Taddeo di Bartolo. The church of the Spedale, dedicated to the Madonna of the Annunciation, was built in the fifteenth century. The bronze Christ over the high altar is by Vecchietta; the organ is said to have been designed by Peruzzi. In the vaults under the Spedale are the meeting-places of several devout confraternities, which are said to trace their origin from the first Sienese Christians, the converts of St Ansanus, who met in secret on this spot in the days of the Roman persecutions. You enter by the last door in the Piazza. The chapel of Santa Maria sotto le Volte dello Spedale, now sometimes called Santa Caterina delle Notti, was the oratory of the "Disciplinati of the Virgin Mary of the Spedale." St Catherine was intimately associated with this confraternity, which was conspicuous for its active works of charity, and to which a number of her disciples belonged. One of her latest letters was written from Rome to the Prior and Brothers of the Company.[104] It was whilst praying here in 1380 that Stefano Maconi heard a voice in his heart telling him that Catherine was dying, and he at once hastened to Rome to receive her last injunctions. In a little cell, adjoining the oratory, St Catherine passed long hours in prayer, and from it she assisted at the offices of the Disciplinati. Here is still shown the hard bed of stone upon which she slept, in the intervals of tending the sick at the hospital. In a room beyond, belonging to the confraternity of St Catherine, are some pictures; a Madonna and Child with Saints by Taddeo di Bartolo, and four small paintings, much restored, in the manner of Girolamo del Pacchia. One of the latter represents the members of the confraternity dressed as you may still see them at the door of St Catherine's house on the day of her festa. Before reaching the oratory, another flight of steps to the left leads down to the meeting-place of the Confraternity of the Madonna. Here are a number of pictures, including a Holy Family by Bazzi; St Catherine leading Pope Gregory back to Rome (though, as a matter of fact, she was present only in spirit) by Benvenuto di Giovanni; a Madonna and Child with Saints by Sano di Pietro. Hung very high up are two small triptychs--the one representing the Crucifixion, Flagellation, Entombment--the other the Blessed Virgin with the two Catherines and other Saints. Mr Berenson ascribes them to Duccio and Fungai respectively. Beyond is the chapel of the confraternity, with
