A third pupil of this school resided a considerable time in Venice, afterwards in Mirandola. This was Gio. Francesco Cassana, a soft and delicate colourist, and master of Langetti. By the Venetians he was but little esteemed, and painted only for private collections. He afterwards repaired to the court of Mirandola, and painted a S. Jerome for the Duomo of that city, and other pictures in various churches, which enhanced his reputation. He was the founder of a family that conferred honour on the art. Niccolo, his eldest son, who became one of the most celebrated portrait painters of his age, passed the chief part of his life at Florence, and died at the court of London. The Grand Duke possesses some of his historical compositions, and some portraits full of expression, in the royal gallery, amongst which are two half figures of two court buffoons, admirably executed. It is said that his style, which nearly approaches to Strozzi, cost him great trouble, and that, when painting, he was so intent on his work as not to hear a person addressing him; and sometimes, in a rage, he would throw himself on the ground, exclaiming against his work as deficient both in colour and spirit, till snatching his pencil again he brought it to his wishes. Gio. Agostino, called l'Abate Cassana, from the clerical dress which he always wore, was a good portrait painter, but distinguished himself more in the representation of animals. There are many of his pictures in the collections of Florence, Venice, and Genoa, and Italy in general, and they often indeed pass under the name of Castiglione. The third brother was Gio. Batista, and excelled in flowers and fruits, which he painted with great effect. They had also a sister, of the name of Maria Vittoria, who painted sacred figures for private collections, and who died in Venice at the beginning of the last century. In all I have said of the Cassana family I have adhered to Ratti, as to a native and correct author. Some who have written on the gallery of Florence, where the portraits of the three first are found, differ in some particulars, ascribing to the one works belonging to the other. Niccolo was in fact the one that there enjoyed the highest favour of Prince Ferdinand; and he it is who is mentioned in the note to Borghini (p. 316) where it is said that the picture by Raffaello, transferred from Pescia to the Pitti palace, was finished by Cassana. But with respect to this notice, and others regarding the Cassani, we may consult the Catalogo Vianelli, p. 97, where we find described a remarkable portrait of a young man studying, painted by Niccolò; and it is succeeded by a long memoir, which throws additional light on the history of this family.
