I made an agreement with a _vetturino_ to take me to Rome for three _louis d'or_ and to be _spesato_. In the carriage were two other passengers, viz., a Neapolitan lady, the wife of a Colonel in the Neapolitan service, and a young Roman, the son of the _Barigello_ or _Capo degli Sbirri_ at Rome. We issued from the _Porta Romana_ at 6 o'clock a.m. the 3d September. The road winds thro' a valley, and has a gentle ascent nearly the whole way to Poggibonsi, where we brought to the first night. The soil hereabouts is far from fertile, but every inch of it is put to profit. The olive tree is very frequent and several farms and villages are to be met with. The next day we arrived at 12 o'clock at Sienna. The approach to Sienna is announced by a quantity of olive trees. The situation of this city being on an elevation, makes it cold and bleak. We remained here three hours, so that I had time to visit some of the places worthy of remark in this venerable city, which is handsome and very solidly built, but has rather a sombre appearance. The _Piazza Grande_ lies in a bottom to which you descend from the environing streets. It is in the shape of a mussel shell and of very large size. The Cathedral is Gothic and is a very majestic and venerable building. Inside it is of black and yellow marble. The pavement of this church contains Scripture histories in mosaic. A library is annexed to the church. The librarian pointed out to me 80 folio volumes of church music with illuminated plates; likewise an ancient piece of sculpture much mutilated, viz., a group of the three Graces. In one of the chapels of this Cathedral are eight columns of _verd-antique_. I observed a monument of the Piccolomini family who belong to this city; one of which family figured a good deal in the Thirty Years' War in Germany. I saw several women in the Cathedral and at the windows of the houses. The greater part of them were handsome. The Italian language is spoken here in its greatest purity; it is the pure Tuscan dialect without the Tuscan aspiration. The Siennese language is in fact the identical _lingua Toscana in bocca Romana_. We arrived the same evening at Buon Convento, an old dismal dirty-looking town formerly fortified; but the country in the environs is pleasing enough. The inn here is very bad. On the road between Sienna and this place I observed a number of mulberry trees.
