But a painter who is the master of his art, elevates or lowers his style according to his subject. The Sybils are in Raffaello's grandest style; and that they are amongst his earliest works, is proved from his having had Timoteo della Vite, as his assistant in them.] [Footnote 44: Lett.

I have seen a similar subject in the Lauretana, belonging to the Signori Pirri, in Rome. At Sassoferrato also, on the great altar of the church of the Capucins, there is a Virgin and child, said to be by him; but it is more probably by Fra Bernardo Catelani. There exist engravings of the two first, but I have not seen any of the last.] [Footnote 47: Riflessioni sopra i tre gran Pittori, &c., cap. i. § 2.] [Footnote 48: Lo dico con questa condizione che V.
