In these variations, however, he never lost sight of that exquisite ease which so much attracts us in his works. He was more particularly attentive to the correct form of beauty, especially in his youthful heads. Here, in the opinion of Mengs, he surpassed all others, and, according to Passeri's expression, he drew faces of Paradise. In these Rome abounds more richly than Bologna itself. The Fortune in the capitol; the Aurora, belonging to the Rospigliosi; the Helen to the Spada; the Herodias to the Corsini; the Magdalen to the Barberini, with other subjects in possession of several princes, are regarded as the wonders of Guido's art. This power of beauty was, in the words of Albano, his most bitter and constant rival, the gift of nature; though the whole was the result of his own intense study of natural beauty, and of Raffaello, and of the ancient statues, medals, and cameos. He declared that the Medicean Venus and the Niobe were his most favourite models; and it is seldom we do not recognize in his paintings either Niobe herself, or one of her children, though diversified in a variety of manner with such exquisite skill, as in no way to appear borrowed. In the same way did Guido derive advantage from Raffaello, Coreggio, Parmigianino, and from his beloved Paul Veronese; from all of whom he selected innumerable beauties, but with such happy freedom of hand as to excite the envy of the Caracci. And, in truth, this artist aimed less at copying beautiful countenances, than at forming for himself a certain general and abstract idea of beauty, as we know was done by the Greeks, and this he modulated and animated in his own style. I find mention, that being interrogated by one of his pupils, _in what part of heaven, in what mould_ existed those wondrous features which he only drew, he pointed to the casts of the antique heads just alluded to, adding, "You too may gather from such examples beauties similar to those in my pictures, if your skill be equal to the task." I find, moreover, that he took for model of one of his Magdalens, the extremely vulgar head of a colour-grinder; but under Guido's hand every defect disappeared, each part became graceful, the whole a miracle. Thus too in his naked figures he reduced them, whatever they were, to a perfect form, more especially in the hands and feet, in which he is singular, and the same in his draperies, which he often drew from the prints of Albert Durer, enriching them, freed from their dryness, with those flowing folds or that grandeur of disposition best adapted to the subject. To portraits themselves, while he preserved the forms and age of the originals, he gave a certain air of novelty and grace, such as we see in that of Sixtus V., placed in the Galli palace at Osimo, or in that wonderful one of Cardinal Spada, in possession of some of his descendants at Rome. There is no one action, position, or expression at all injurious to his figures; the passions of grief, terror, sorrow, are all combined with the expression of beauty; he turns them every way as he lists, he changes them into every attitude, always equally pleasing, and every one equally entitled to the eulogy of displaying in every action, and in every step, the beauty which secretly animates and accompanies it.[33]
