Giovanni Maria Butteri, and Lorenzo dello Sciorina, were two other scholars of Bronzino, and assisted Vasari in the above mentioned pictures on the escrutoire, and in his preparations for festivals. The first imitated Vasari, his master, and Titi; but at all times his colouring was inharmonious; the second has little to boast of beyond his design. Both are honourably mentioned among the academicians; as is also Stefano Pieri, who assisted Vasari in the cupola of the metropolitan church. The sacrifice of Isaac, of the Pitti palace, is ascribed to him, and it is the best of his works executed at Rome, which are censured as hard and dry by Baglione. Cristofano dell'Altissimo, whose talent lay in portrait painting, may be added to these. Giovio had formed the celebrated collection of portraits of illustrious men, which is still preserved at Como, though now divided between the two families of the Conti Giovio, one of which possesses the portraits of learned men, the other those of warriors. From this collection, which the prelate styled his museum, that still existing at Mondragone was copied, and also the collection now in the Florentine gallery, by the labours of Cristofano, who was sent for that purpose to Como by Cosmo I. He copied the features of those celebrated men, but attended little to other circumstances; whence it happens that the Giovian collection exhibits many very dissimilar manners, the Medicean one alone; but the features of the originals are very faithfully expressed. Michele di Ridolfo del Ghirlandaio instructed many artists in this epoch. From his school, proceeded Girolamo Macchietti, or G. del Crocifissaio, the assistant of Vasari for six years, who afterwards studied for two years at Rome, though already an adept in the art. His example merits imitation, for that school speaks more to the eye than the ear; and he who there employs his eyes judiciously, cannot fail to reap the advantage. After his return to Florence he finished a few valuable pictures with care and assiduity, among which may be noticed an Epiphany for the chapel of the Marquis Della Stufa, at S. Lorenzo, and a martyrdom of S. Lorenzo S. Maria Novella, which is greatly praised by Lomazzo. Borghini also, after commending the beauty, the expression, and the picture in general, scarcely found any thing to censure. It is certainly among the most striking pictures in that church. Macchietti also went to Spain, and was not a little employed at Naples and at Benevento, where he is said to have painted his best pictures. In the Dizionario Storico of the professors of the fine arts at Urbino (Colucci tom. xxxi.) I find mention that Girolamo Macchietti produced some battle-pieces for the hall of the Albani at S. Giovanni; but I see no reason why he should be admitted to a place among native artists belonging to that city, or to the state of Urbino.
