Meanwhile there was brought to Milan by a Fleming a head of a young man, taken from life and painted in oils, which was admired by everyone in that city; but Giovan Francesco, seeing it, laughed and said: "I am confident that I can do a better." At which the Fleming mocked him, but after many words the matter came to this, that Giovan Francesco was to try his hand, losing his own picture and twenty-five crowns if he lost, and winning the Fleming's head and likewise twenty-five crowns if he won. Setting to work, therefore, with all his powers, Giovan Francesco made a portrait of an aged gentleman with shaven face, with a falcon on his wrist; but, although this was a good likeness, the head of the Fleming was judged to be the better. Giovan Francesco did not make a good choice in executing his portrait, for he took a head that could not do him honour; whereas, if he had chosen a handsome young man, and had made as good a likeness of him as he did of the old man, he would at least have equalled his adversary's picture, even if he had not surpassed it. But for all this the head of Giovan Francesco did not fail to win praise, and the Fleming showed him courtesy, for he contented himself with the head of the shaven old man, and, being a noble and courteous person, would by no means accept the five-and-twenty crowns. This picture came after some time into the possession of Madonna Isabella d'Este, Marchioness of Mantua, who paid a very good price for it to the Fleming and placed it as a choice work in her study, in which she had a vast number of very beautiful coins, pictures, works in marble, and castings. After completing his work for Visconti, Giovan Francesco, being invited by Guglielmo, Marquis of Montferrat, went willingly to serve him, as Visconti straitly besought him to do. On his arrival, a fine provision was assigned to him; and, setting to work, he painted for that noble at Casale, in a chapel where he heard Mass, as many pictures as were necessary to fill it and adorn it on every side, with subjects from the Old Testament and the New, which were executed by him with supreme diligence, as was also the chief altar-piece. He then executed many works throughout the apartments of that Castle, which brought him very great fame. And in S. Domenico, by order of that Marquis, he painted the whole of the principal chapel for the adornment of the tomb wherein he was to be laid to rest; in which work Giovan Francesco acquitted himself so well, that he was rightly rewarded with honourable gifts by the liberality of his patron, who also favoured him by making him one of his own chamberlains, as may be seen from an instrument that is in the possession of his heirs at Verona. He made portraits of that lord and of his wife, with many pictures that they sent to France, and also the portrait of Guglielmo, their eldest child, who was then a boy, and likewise portraits of their daughters and of all the ladies who were in the service of the Marchioness.
