The following morning, having engaged a guide from the hotel, we desired him to take us to the places of most interest. Accordingly, he led us through the long, narrow main street of Sienna, where there is scarcely room for two carriages to pass, and no footways, and all paved, according to Italian mode, with large flagstones. There are shops in this street, and, I think, nowhere else, but of a very inferior description. It terminates near the Collegio Tolomei, which we entered to see a large gallery of the old masters, including some good paintings, one especially by Perugino. From this we proceeded to the cathedral, which is built in alternate courses of black and white marble, the façade very richly ornamented. The interior, though highly adorned, is not so rich in works of art as the Cathedral of Pisa. The interior pavement, composed of marble mosaics, representing Old Testament scenes, had unfortunately been so much worn by the worshippers’ feet as to require to be boarded over for protection; but a part of the boarding is removed, to allow the visitor to see a portion as a specimen. We were shown into the library, which is surrounded by huge illuminated tombs, some of which lie open for inspection. It is a great lofty hall, ornamented by sculpture and by large frescoes, executed by a fellow–pupil of Raphael, his great master having been said to have had a hand in the designs. These frescoes are very bright and perfect, and were among the best we saw anywhere in Italy. Leaving the cathedral, and just looking in at the baptistery below, we crossed over to the large open place called the Piazza Vittorio Emanuele. Here a curious sight met our eyes. A dentist, who had been driving through the town in a carriage and four, with a band of music to congregate the people, stood on the box of the carriage among a crowd of people, and was gratuitously extracting their decayed teeth as fast as the unfortunates could pass up to him. The patient was seated, a moment’s inspection, the tooth (probably the right one, not impossibly occasionally the wrong one) was drawn and tossed into the air among the crowd; the person so operated on descended, relieved, on the other side, and in a twinkling another unhappy one took his place to be similarly treated. We understood that the operator was paid from some charitable source. * * * * * Several public buildings are situated in the Piazza, and among them the town or public hall, containing many frescoes and paintings, through which we were conducted. A very high, slender–looking tower or campanile rises from it, and is one of the most prominent objects in Sienna. Leaving the town–hall, we walked to the Instituto delle Belle Arti, which contains a collection of old paintings, particularly of the school of Sienna, principally interesting to the student; thence to the large Church of St. Domenico, where are various paintings, and among others, frescoes by Sodoma.
