That distemper was not very highly esteemed by the Venetians may be inferred from the following observation of Pino:—"Il modo di colorir à guazzo è imperfetto et più fragile et à me non diletta onde lasciamolo all' oltremontani i quali sono privi della vera via." It is, however, certain that the Venetians sometimes painted in this style, and Volpato mentions several works of the kind by Bassan, but he never hints that he began his oil pictures in distemper.

Boschini says, that the Venetians (he especially means Titian) rendered their pictures sparkling by finally touching on a dry surface (à secco). The absence of varnish in the solid colours, the retouching with spirit of turpentine, and even à secco, all suppose a dull surface, which would require varnish. The latter method, alluded to by Boschini, was an exception to the general practice, and not likely to be followed on account of its difficulty. Carlo Maratti, on the authority of Palomino, used to say, "He must be a skilful painter who can retouch without oiling out."

See a letter by Francesco Bocchi, and another by Vasari, in the "Lettere Pittoriche" of Bottari. The circumstance is mentioned incidentally; the point chiefly dwelt on is, that some persons who passed were deceived, and bowed to the picture, supposing it to be the pope.

Federici, "Memorie Trevigiane," Venezia, 1803. The altar-piece of S. Niccolo at Treviso is attributed, in the document alluded to, to Fra Marco Pensabene, a name unknown; the painting is so excellent as to have been thought worthy of Sebastian del Piombo: for this opinion, however, there are no historical grounds. It was begun in 1520, but before it was quite finished the painter, whoever he was, absconded: it was therefore completed by another.
