It appears no improbable conjecture that Raffaello, after settling the plan and fully arranging the figures of his picture, drew the nudities of this design as the bases of his draperies: for this reason only, the principal parts of the forms, and those muscles that would act most visibly on the draperies, are designed correctly, and finished with decision; whilst the heads, and what was either to be naked in the picture or did not act immediately on the drapery, remained in careless and superficial lines. That Raffaello suffered parts of his Transfiguration, and in my opinion some of the most important parts, to receive all but the last finish from a pupil, if tradition had not told us, there is ocular demonstration in the picture itself. The proportions of the Demoniac's father are neglected as a whole, in relation of limb to limb, and the figure is sacrificed to place. The face of Christ himself, as it was seen in the Louvre, is unworthy of Raffaello's hand and conception.[98] The reason why some of the figures are drawn in the true spirit of the artist, and others in a bald and insignificant manner, may be, that after slightly sketching the whole, he gave his own finish in the design to those parts only which he intended to execute with his own hand in the picture; and less solicitous for the rest, left them to the hand of some inferior pupil. The height of this extraordinary design is one foot eight inches four lines; its breadth one foot two inches five lines; it is without injury. * * * * * Taddeo and Federigo Zuccari, the first declared mannerists of this school, sons of Ottaviano Zuccari, a mediocre painter of S. Angiolo in Vado, came to Rome successively, formed a school, and filled towns and states with an immense farrago of good, tolerable, and bad pictures. From the instructions of Pompeo da Fano and Giacomone da Faenza, but chiefly from an obstinate study of Raffaello's works, Taddeo, at no protracted period, gathered enough to diffuse over his own, an air, though not reality, of style, and to anticipate by contrivance and facility the rewards which time owes to invention and genius. Courting the senses of the multitude, he became the hero of the day; they saw their portraits in his faces, their limbs in his forms, their action in his attitudes; his draperies, hair, beards, had a cut of fashion. The simplicity of his disposition is often contrasted by half figures emerging from his foregrounds; perhaps less from a principle of imitating his more remote predecessors, than to invigorate the effect of his chiaroscuro, a method not unknown to Parmegiano.
