Among those who worked with Rosso on the aforesaid decorations in stucco and relief, and beloved by him beyond all the others, were the Florentine Lorenzo Naldino, Maestro Francesco of Orleans, Maestro Simone of Paris, Maestro Claudio, likewise a Parisian, Maestro Lorenzo of Picardy, and many others. But the best of them all was Domenico del Barbieri, who is an excellent painter and master of stucco, and a marvellous draughtsman, as is proved by his engraved works, which may be numbered among the best in common circulation. The painters, likewise, whom he employed in those works at Fontainebleau, were Luca Penni, brother of Giovan Francesco Penni, called Il Fattore, who was a disciple of Raffaello da Urbino; the Fleming Leonardo, a very able painter, who executed the designs of Rosso to perfection in colours; Bartolommeo Miniati, a Florentine; with Francesco Caccianimici, and Giovan Battista da Bagnacavallo. These last entered his service when Francesco Primaticcio went by order of the King to Rome, to make moulds of the Laocoon, the Apollo, and many other choice antiquities, for the purpose of casting them afterwards in bronze. I say nothing of the carvers, the master-joiners, and innumerable others of whom Rosso availed himself in those works, because there is no need to speak of them all, although many of them executed works worthy of much praise. In addition to the things mentioned above, Rosso executed with his own hand a S. Michael, which is a rare work. For the Constable he painted a panel-picture of the Dead Christ, a choice thing, which is at a seat of that noble, called Ecouen; and he also executed some exquisite miniatures for the King. He then drew a book of anatomical studies, intending to have it printed in France; of which there are some sheets by his own hand in our book of drawings. Among his possessions, also, after he was dead, were found two very beautiful cartoons, in one of which is a Leda of singular beauty, and in the other the Tiburtine Sibyl showing to the Emperor Octavian the Glorious Virgin with the Infant Christ in her arms. In the latter he drew the King, the Queen, their Guard, and the people, with such a number of figures, and all so well drawn, that it may be said with truth that this was one of the most beautiful things that Rosso ever did.
