Note 21 — BOOK III.
Thomas Roscoe translation
Vasari, at the close of his Life observes, "none of his scholars ever equalled Pietro in application or in amenity of colour." Padre della Valle asserts on the contrary, "that he was indebted for a great portion of his celebrity to the talents displayed by his scholars;" and says that he detected the touch of Raffaello in his picture in the Grand Duke's collection; but we must have a stronger testimony before we submit ourselves to this decision.
