All these beautiful manners and arts being spent in the time of Andrea, that alone was in use which had been brought by the Goths and by the uncivilized Greeks into Tuscany. Wherefore he, having studied the new method of design of Giotto and those few antiquities that were known to him, refined in great part the grossness of so miserable a manner with his judgment, in such wise that he began to work better and to give much greater beauty to statuary than any other had yet done in that art up to his times. Therefore, his genius and his good skill and dexterity becoming known, he was assisted by many in his country, and while still young he was commissioned to make for S. Maria a Ponte some little figures in marble, which brought him so good a name that he was sought out with very great insistence to come to work in Florence for the Office of Works of S. Maria del Fiore, which, after a beginning had been made with the façade containing the three doors, was suffering from a dearth of masters to make the scenes that Giotto had designed for the beginning of the said fabric. Andrea, then, betook himself to Florence, for the service of the said Office of Works. And because the Florentines desired at that time to gain the friendship and love of Pope Boniface VIII, who was then Supreme Pontiff of the Church of God, they wished that, before anything else, Andrea should make a portrait in marble of the said Pontiff, from the life. Wherefore, putting his hand to this work, he did not rest until he had finished the figure of the Pope, with a S. Peter and a S. Paul who are one on either side of him; which three figures were placed in the façade of S. Maria del Fiore, where they still are. Andrea then made certain little figures of prophets for the middle door of the said church, in some shrines or rather niches, from which it is seen that he had brought great betterment to the art, and that he was in advance, both in excellence and design, of all those who had worked up to then on the said fabric. Wherefore it was resolved that all the works of importance should be given to him to do, and not to others; and so, no long time after, he was commissioned to make the four statues of the principal Doctors of the Church, S. Jerome, S. Ambrose, S. Augustine, and S. Gregory. And these being finished and acquiring for him favour and fame with the Wardens of Works—nay, with the whole city—he was commissioned to make two other figures in marble of the same size, which were S. Stephen and S. Laurence, now standing in the said façade of S. Maria del Fiore, at the outermost corners. By the hand of Andrea, likewise, is the Madonna in marble, three braccia and a half high, with the Child in her arms, which stands on the altar of the little Church of the Company of the Misericordia, on the Piazza di S. Giovanni in Florence; which was a work much praised in those times, and above all because he accompanied it with two angels, one on either side, each two braccia and a half high. Round this work there has been made in our own day a frame of wood, very well wrought by Maestro Antonio, called Il Carota; and below, a predella full of most beautiful figures coloured in oil by Ridolfo, son of Domenico Ghirlandajo. In like manner, that half-length Madonna in marble that is over the side door of the same Misericordia, in the façade of the Cialdonai, is by the hand of Andrea, and it was much praised, because he imitated therein the good ancient manner, contrary to his wont, which was ever far distant from it, as some drawings testify that are in our book, wrought by his hand, wherein are drawn all the stories of the Apocalypse.
Now, seeing that Andrea had applied himself in his youth to the study of architecture, there came occasion for him to be employed in this by the Commune of Florence; for Arnolfo being dead and Giotto absent, he was commissioned to make the design of the Castle of Scarperia, which is in the Mugello, at the foot of the mountains. Some say, although I would not indeed vouch for it as true, that Andrea stayed a year in Venice, and there wrought, in sculpture, some little figures in marble that are in the façade of S. Marco, and that at the time of Messer Piero Gradenigo, Doge of that Republic, he made the design of the Arsenal; but seeing that I know nothing about it save that which I find to have been written by some without authority, I leave each one to think in his own way about this matter. Andrea having returned from Venice to Florence, the city, fearful of the coming of the Emperor, caused a part of the walls to be raised with lime post-haste to the height of eight braccia, employing in this Andrea, in that portion that is between San Gallo and the Porta al Prato; and in other places he made bastions, stockades, and other ramparts of earth and of wood, very strong.

Now because, three years before, he had shown himself to his own great credit to be an able man in the casting of bronze, having sent to the Pope in Avignon, by means of Giotto, his very great friend, who was then staying at that Court, a very beautiful cross cast in bronze, he was commissioned to complete in bronze one of the doors of the Church of S. Giovanni, for which Giotto had already made a very beautiful design; this was given to him, I say, to complete, by reason of his having been judged, among so many who had worked up to then, the most able, the most practised and the most judicious master not only of Tuscany but of all Italy. Wherefore, putting his hand to this, with a mind determined not to consent to spare either time, or labour, or diligence in executing a work of so great importance, fortune was so propitious to him in the casting, for those times when the secrets were not known that are known to-day, that within the space of twenty-two years he brought it to that perfection which is seen; and what is more, he also made during that same time not only the shrine of the high-altar of S. Giovanni, with two angels, one on either side of it, that were held something very beautiful, but also, after the design of Giotto, those little figures in marble that act as adornment for the door of the Campanile of S. Maria del Fiore, and round the same Campanile, in certain mandorle, the seven planets, the seven virtues, and the seven works of mercy, little figures in half-relief that were then much praised. He also made during the same time the three figures, each four braccia high, that were set up in the niches of the said Campanile, beneath the windows that face the spot where the Orphans now are—that is, towards the south; which figures were thought at that time more than passing good. But to return to where I left off: I say that in the said bronze door are little scenes in low relief of the life of S. John the Baptist, that is, from his birth up to his death, wrought happily and with much diligence. And although it seems to many that in these scenes there do not appear that beautiful design and that great art which are now put into figures, yet Andrea deserves nothing but the greatest praise, in that he was the first to put his hand to the complete execution of such a work, which afterwards enabled the others who lived after him to make whatever of the beautiful, of the difficult and of the good is to be seen at the present day in the other two doors and in the external ornaments. This work was placed in the middle door of that church, and stood there until the time when Lorenzo Ghiberti made that one which is there at the present day; for then it was removed and placed opposite the Misericordia, where it still stands. I will not forbear to say that Andrea was assisted in making this door by Nino, his son, who was afterwards a much better master than his father had been, and that it was completely finished in the year 1339, that is, not only made smooth and polished all over, but also gilded by fire; and it is believed that it was cast in metal by some Venetian masters, very expert in the founding of metals, and of this there is found record in the books of the Guild of the Merchants of Calimara, Wardens of the Works of S. Giovanni.
While the said door was making, Andrea made not only the other works aforesaid but also many others, and in particular the model of the Church of S. Giovanni at Pistoia, which was founded in the year 1337. In that same year, on January 25, in excavating the foundations of this church, there was found the body of the Blessed Atto, once Bishop of that city, who had been buried in that place one hundred and thirty-seven years. The architecture, then, of this church, which is round, was passing good for those times. In the principal church of the said city of Pistoia there is also a tomb of marble by the hand of Andrea, with the body of the sarcophagus full of little figures, and some larger figures above; in which tomb is laid to rest the body of Messer Cino d' Angibolgi, Doctor of Laws, and a very famous scholar in his time, as Messer Francesco Petrarca testifies in that sonnet:
Piangete, donne, e con voi pianga Amore;
and also in the fourth chapter of the Triumph of Love, where he says:
Ecco Cin da Pistoia, Guitton d'Arezzo,
Che di non esser primo par ch'ira aggia.
