there a sudden glimpse of a rose garden, or a fig tree in a little cortile bending its branches over the way. In the less picturesque Via San Quirico is the church of San Quirico, perhaps the oldest in Siena, but now modernised. By the side of it, an irritating piece of wall cuts off what should be a superb view of the Duomo. In the same street are the remains of the little church of Sant' Ansano in Castelvecchio, which was possibly the first baptistery of Siena and of which there is documentary evidence as far back as the year 881.[139] Near it stands an old tower, the Rocchetta, which is probably the only remnant of the first castle and certainly the most venerable piece of masonry left in Siena; according to the legend, it was here that St Ansanus himself was imprisoned by the Roman governor before his martyrdom. In the Via delle Murelle (now Via Tommaso Pendola) is the chapel of the Contrada della Tartuca. This part of Siena is rich in charitable institutions. On either side of the street is a great institute for the Deaf and Dumb, and in the refectory of an old convent of the Poor Clares (now the female side of the Institute) the Sisters of Charity show you a beautiful fresco of the Last Supper with scenes from the Passion above. It appears to be the work of some Sienese master of the latter part of the Quattrocento, who had, perhaps, seen Andrea del Castagno's rendering of the same theme in Santa Appollonia at Florence. The last house in the Via Stalloreggi, on the left, is the one in which Duccio painted his glorious masterpiece, and it was hither that the procession came, to take it in triumph to its place beneath the cupola of the Duomo. Then we pass out of the old city, under the Arco delle due Porte, into the Piazza del Carmine, now a part of the Via Baldassare Peruzzi.
