Agostino, wherein he portrayed Pope Gregory XI--namely, the Pope who brought the Court back to Italy after it had been so many decades of years in France. [Illustration: POLYPTYCH (_After the panel by_ Taddeo Bartoli. _Perugia: Gallery 9_) _Anderson_] Returning after these works to Siena, he made no very long stay there, because he was called to work at Perugia in the Church of S. Domenico, where, in the Chapel of S. Caterina, he painted in fresco all the life of that Saint; and in S. Francesco, beside the door of the sacristy, he made some figures which, although to-day little can be discerned of them, are known to be by the hand of Taddeo, who held ever to one unchanging manner. A little time afterwards there befell the death of Biroldo, Lord of Perugia, who was murdered in the year 1398; whereupon Taddeo returned to Siena, where, labouring continually, he applied himself so zealously to the studies of his art, in order to become an able painter, that it can be affirmed, if perchance he did not realize his intention, that this was certainly not by reason of any defect or negligence that he showed in his work, but rather through indisposition caused by an internal obstruction, which afflicted him in a manner that he could not attain to the fulness of his desire. Having taught the art to one his nephew, called Domenico, Taddeo died at the age of fifty-nine; and his pictures date about the year of our salvation 1410. He left, then, as it has been said, Domenico Bartoli, his nephew and disciple, who, following the art of painting, painted with greater and better mastery, and in the scenes that he wrought he showed much more fertility, varying them in diverse ways, than his uncle had done. In the pilgrim's hall of the great hospital at Siena there are two large scenes, wrought in fresco by Domenico, wherein are seen perspectives and other adornments very ingeniously composed. Domenico is said to have been modest and gentle, and a man of singular amiability and most liberal courtesy; and this is said to have done no less honour to his name than the art of painting itself. His works date about the year of our Lord 1436, and the last were a panel containing an Annunciation in S. Trinita in Florence, and the panel of the high-altar in the Church of the Carmine. There lived at the same time and painted in almost the same manner, although he made the colouring more brilliant and the figures lower, one Alvaro di Piero, a Portuguese, who made many panels in Volterra, and one in S. Antonio in Pisa, and others in other places, whereof, seeing that they are of no great excellence, there is no need to make further record. In our book there is a drawing made with great mastery by Taddeo, wherein are Christ and two angels. [Illustration: DOMENICO BARTOLI: MADONNA ORANS (_Siena: Refugio.
