He instructed in the art a son, called Francesco di Simone, who was highly extolled for a Madonna in chiaroscuro, in the church of S. Chiara, and which was one of the works which escaped being effaced on the occasion before mentioned. He had two other scholars in Gennaro di Cola, and Stefanone, who were very much alike in their manner, and on that account were chosen to paint in conjunction some large compositions, such as the pictures of the Life of S. Lodovico, Bishop of Tolosa, which Simone had only commenced, and various others of the Life of the Virgin, in S. Giovanni da Carbonara, which were preserved for a long period. Notwithstanding the similarity of their styles, we may perceive a difference in the genius of the two artists; the first being in reference to the second, studied and correct, and anxious to overcome all difficulties, and to elevate the art; on which account he appears occasionally somewhat laboured: the second discovers more genius, more confidence, and a greater freedom of pencil, and to his figures he gives a spirit that might have assured him a distinguished place, if he had been born at a more advanced period of art. Before Zingaro (who will very soon occupy our attention) introduced a manner acquired in other schools, the art had made little progress in Naples and her territories. This is clearly proved by Colantonio del Fiore, the scholar of Francesco, who lived till the year 1444, of whom Dominici mentions some pictures, though he is in doubt whether they should not be assigned to Maestro Simone; which is a tacit confession, that in the lapse of a century the art had not made any considerable progress. It appears, however, that Colantonio after some time, by constant practice, had considerably improved himself; having painted several works in a more modern style, particularly a S. Jerome, in the church of S. Lorenzo, in the act of drawing a thorn from the foot of a lion, with the date of 1436. It is a picture of great truth, removed afterwards, for its merit, by the P. P. Conventuali, into the sacristy of the same church, where it was for a long time the admiration of strangers. He had a scholar of the name of Angiolo Franco, who imitated better than any other Neapolitan the manner of Giotto; adding only a stronger style of chiaroscuro, which he derived from his master.
