Bavaria and the Anti-Pope Nicholas V. Some, likewise, believe that Giotto designed the castle and fortress of Giusta, which is impregnable, at San Frediano, in the same city of Lucca.
Afterwards, Giotto having returned to Florence, Robert, King of Naples, wrote to Charles, King of Calabria, his first-born son, who chanced to be in Florence, that he should send him Giotto to Naples at all costs, for the reason that, having finished the building of S. Chiara, a convent of nuns and a royal church, he wished that it should be adorned by him with noble paintings. Giotto, then, hearing himself summoned by a King so greatly renowned and famous, went more than willingly to serve him, and, on arriving, painted many scenes from the Old Testament and the New in some chapels of the said convent. And the scenes from the Apocalypse that he made in one of the said chapels are said to have been inventions of Dante; and this may be also true of those at Assisi, so greatly renowned, whereof there has been enough said above. And although Dante at that time was dead, they may have held discourse on these matters, as often comes to pass between friends.
But to return to Naples; Giotto made many works in the Castel dell'Uovo, and in particular the chapel, which much pleased that King, by whom he was so greatly beloved that many times, while working, Giotto found himself entertained by the King in person, who took pleasure in seeing him at work and in hearing his discourse. And Giotto, who had ever some jest on his tongue and some witty repartee in readiness, would entertain him with his hand, in painting, and with pleasant discourse, in his jesting. Wherefore, the King saying to him one day that he wished to make him the first man in Naples, Giotto answered, "And for that end am I lodged at the Porta Reale, in order to be the first in Naples." Another time, the King saying to him, "Giotto, an I were you, now that it is hot, I would give over painting for a little;" he answered, "And I, i' faith, an I were you." Being then very dear to the King, he made for him a good number of pictures in a hall (that King Alfonso I pulled down in order to make the Castle), and also in the Incoronata; and among others in the said hall were the portraits of many famous men, and among them that of Giotto himself. Now the King having one day out of caprice besought him to paint his realm for him, Giotto, so it is said, painted for him an ass saddled, that had at its feet a new pack-saddle, and was sniffing at it and making semblance of desiring it; and on both the old pack-saddle and the new one were the royal crown and the sceptre of sovereignty; wherefore Giotto, being asked by the King what such a picture signified, answered that such were his subjects and such the kingdom, wherein every day a new lord was desired.
