Baccio d'Agnolo afterwards laid the architrave, frieze, and cornice, as will be told below. It is true that, as it appears from some designs by his hand that are in our book, he wished to make another arrangement of frieze, cornice, and gallery, with pediments on each of the eight sides of the cupola; but he had not time to put this into execution, for, being carried away by an excess of work from one day to another, he died.

Before this happened, however, he went to Naples and designed the architecture of the magnificent Palace at Poggio Reale for King Alfonso, with the beautiful fountains and conduits that are in the courtyard. In the city, likewise, he made designs for many fountains, some for the houses of noblemen and some for public squares, with beautiful and fanciful inventions; and he had the said Palace of Poggio Reale all wrought with paintings by Piero del Donzello and his brother Polito. Working in sculpture, likewise, for the said King Alfonso, then Duke of Calabria, he wrought scenes in low-relief over a door (both within and without) in the great hall of the Castle of Naples; and he made a marble gate for the castle after the Corinthian Order, with an infinite number of figures, giving to that work the form of a triumphal arch, on which stories from the life of that King and some of his victories are carved in marble. Giuliano also wrought the decorations of the Porta Capovana, making therein many varied and beautiful trophies; wherefore he well deserved that great love should be felt for him by that King, who, rewarding him liberally for his labours, enriched his descendants.

Giuliano had taught to his nephew Benedetto the arts of tarsia and architecture, and something about working in marble; and Benedetto was living in Florence, devoting himself to working at tarsia, because this brought him greater gains than the other arts did. Now Giuliano was summoned to Rome by Messer Antonio Rosello of Arezzo, Secretary to Pope Paul II, to enter the service of that Pontiff. Having gone thither, he designed the loggie of travertine in the first court of the Palace of S. Pietro, with three ranges of columns, of which the first is on the lowest floor, where there are now the Signet Office and other offices; the second is above this, where the Datary and other prelates live; and the third and last is where those rooms are that look out on the court of S. Pietro, which he adorned with gilded ceilings and other ornaments. From his design, likewise, were made the marble loggie from which the Pope gives his benediction—a very great work, as may still be seen to-day. But the most stupendous and marvellous work that he made was the palace that he built for that Pope, together with the Church of S. Marco in Rome, for which there was used an infinite quantity of travertine blocks, said to have been excavated from certain vineyards near the Arch of Constantine, where they served as buttresses for the foundations of that part of the Colosseum which is now in ruins, perchance because of the weakening of that edifice.

Giuliano was sent by the same Pontiff to the Madonna of Loreto, where he rebuilt the foundations and greatly enlarged the body of the church, which had formerly been small and built over piers in rustic-work. He did not go higher than the string-course that was there already; but he summoned his nephew Benedetto to that place, and he, as will be told, afterwards raised the cupola. Being then forced to return to Naples in order to finish the works that he had begun, Giuliano received a commission from King Alfonso for a gate near the castle, which was to include more than eighty figures, which Benedetto had to execute in Florence; but the whole remained unfinished by reason of the death of that King. There are still some relics of these figures in the Misericordia in Florence, and there were others in our own day in the Canto alla Macine; but I do not know where these are now to be found. Before the death of the King, however, Giuliano died in Naples at the age of seventy, and was greatly honoured with rich obsequies; for the King had fifty men clothed in mourning, who accompanied Giuliano to the grave, and then he gave orders that a marble tomb should be made for him.

The continuation of his work was left to Polito, who completed the conduits for the waters of Poggio Reale. Benedetto, devoting himself afterwards to sculpture, surpassed his uncle Giuliano in excellence, as will be told; and in his youth he was the rival of a sculptor named Modanino da Modena, who worked in terra-cotta, and who wrought for the said Alfonso a Pietà with an infinite number of figures in the round, made of terra-cotta and coloured, which were executed with very great vivacity, and were placed by the King in the Church of Monte Oliveto, a very highly honoured monastery in the city of Naples. In this work the said King is portrayed on his knees, and he appears truly more than alive; wherefore Modanino was remunerated by him with very great rewards. But when the King died, as it has been said, Polito and Benedetto returned to Florence; where, no long time after, Polito followed Giuliano into eternity. The sculptures and pictures of these men date about the year of our salvation 1447.
