The Buono family form a curious connection between Corneto Tarquinia and Pistoja. We have already spoken of the Ciborium at Corneto, sculptured by Johannes and Guitto (Guido) in 1168. The pulpit in the same church, and another at Alba Fucense, are both signed by Giovanni Buono and Andrea his brother, but date a century later than the Ciborium, _i.e._ precisely the time of our Giovanni Buono of Pistoja. The façade of the same church at Corneto Tarquinia is full of Comacine sculptures; and on the double-arched windows with the tesselated columns is an epigraph saying that the "inlaid work in porphyry, serpentine, and _giallo antico_" was done by Nicolao, son of Ranuccio. Now this must have been the Nicolao who worked under this same Giovanni Buono in 1280 at Parma, with a certain Guido and Johannes Benvenuti. Guido was evidently a kinsman of Giovanni Buono, for we find that in 1285 Albertus, son of Guido Buono, and Albertinus, son of Enrico Buono, were employed together in the sculptures at S. Pietro at Bologna. In any case we have a long connection of the Buono family with the Opera di S. Jacopo at Pistoja, and shall find them still engaged in other important works at Pisa and Lucca, besides being chief architects at Parma and Padua, etc. Two centuries later their descendants were building fine Gothic works in Venice. The Baptistery of Pistoja has been attributed to Andrea Pisano, but a document in the archives of the Opera di S. Jacopo not only shows who was the real architect, or rather head-master, but proves that it was done by a Magister Cellini of the Masonic Guild from the lodge at Siena, who became Grand Master of the lodge at Pistoja. It runs--"Et per Magistrum Cellinum qui est caput magistrorum edificantium Ecclesiam rotundam S. Joannis Baptistæ."[190] There also exists in the archives the contract made between the _Opera_ (administrative council) and Magister Cellini on July 22, 1339, for the completion and ornamentation of the building which he had so far constructed. There is no mention of Andrea Pisano in either deed. The Pistojan Baptistery is not a very pleasing building. There is something inharmonious in its proportions. It is of the usual octagonal form, but too high for its width; the horizontal lines of white and black marble still further detract from its beauty, and cut up the ornamentation.
