But to return to Luca; the said work being finished and giving great satisfaction, he was entrusted with the bronze door of the said sacristy, which he divided into ten squares—namely, five on either side, making the head of a man at every corner of each square, in the border; and he varied the heads one from another, making young men, old, and middle-aged, some bearded and some shaven, and, in short, each one beautiful of its kind in diverse fashions, so that the framework of that door was beautifully adorned. Next, in the scenes in the squares—to begin at the upper part—he made the Madonna with the Child in her arms, with most beautiful grace; and in the one beside it, Jesus Christ issuing from the Sepulchre. Below these, in each of the first four squares, is the figure of an Evangelist; and below these, the four Doctors of the Church, who are writing in different attitudes. And the whole of this work is so highly finished and polished that it is a marvel, and gives us to know that it was a great advantage to Luca to have been a goldsmith.
But since, on reckoning up after these works how much there had come to his hand and how much time he spent in making them, he recognized that he had gained very little and that the labor had been very great, he resolved to abandon marble and bronze and to see whether he could gather better fruits from another method. Wherefore, reflecting that clay could be worked easily and with little labor, and that it was only necessary to find a method whereby works made with it might be preserved for a long time, he set about investigating to such purpose that he found a way to defend them from the injuries of time; for, after having made many experiments, he found that by covering them with a coating of glaze, made with tin, litharge, antimony, and other minerals and mixtures fused together in a special furnace, he could produce this effect very well and make works in clay almost eternal. For this method of working, as being its inventor, he gained very great praise, and all the ages to come will therefore owe him an obligation.
Having then succeeded in this as much as he could desire, he resolved that his first works should be those that are in the arch over the bronze door which he had made for the sacristy, below the organ of S. Maria del Fiore; and therein he made a Resurrection of Christ, so beautiful for that time that it was admired, when placed in position, as something truly rare. Moved by this, the said Wardens of Works desired that the arch over the door of the other sacristy, where Donatello had made the ornament of the other organ, should be filled by Luca in the same manner with similar figures and works in terra-cotta; wherefore Luca made therein a very beautiful Jesus Christ ascending into Heaven.
Now, not being yet satisfied with this beautiful invention—so lovely and so useful, above all for places where there is water, and where, because of damp or other reasons, there is no scope for paintings—Luca went on seeking further progress, and, instead of making the said works in clay simply white, he added the method of giving them color, with incredible marvel and pleasure to all. Wherefore the Magnificent Piero di Cosimo de’ Medici, one of the first to commission Luca to fashion colored works in clay, caused him to execute the whole of the round vaulting of a study in the Palace—built, as it will be told, by his father Cosimo—with various things of fancy, and likewise the pavement, which was something singular and very useful for the summer. And seeing that this method was then very difficult, and that many precautions were necessary in the firing of the clay, it is certainly a marvel that Luca could execute these works with so great perfection that both the vaulting and the pavement appear to be made, not of many pieces, but of one only. The fame of these works spreading not only throughout Italy but throughout all Europe, there were so many who desired them that the merchants of Florence, keeping Luca, to his great profit, continually at this labor, sent them throughout the whole world. And because he could not supply the whole, he took his brothers, Ottaviano and Agostino, away from the chisel, and set them to work on these labors, wherein the three of them together gained much more than they had done up to then with the chisel, for the reason that, besides those of their works that were sent to France and Spain, they also wrought many things in Tuscany; and in particular, for the said Piero de’ Medici, in the Church of S. Miniato al Monte, the vaulting of the marble chapel, which rests on four columns in the middle of the church, and which they divided most beautifully into octagons. But the most notable work of this kind that ever issued from their hands was the vaulting of the Chapel of S. Jacopo, where the Cardinal of Portugal is buried, in the same church. In this, although it has no salient angles, they made the four Evangelists in four medallions at the corners, and the Holy Spirit in a medallion in the middle of the vaulting, filling the other spaces with scales which follow the curve of the vaulting and diminish little by little till they reach the centre, insomuch that there is nothing better of that kind to be seen, nor anything built and put together with more diligence.
Next, in a little arch over the door of the Church of S. Piero Buonconsiglio, below the Mercato Vecchio, he made the Madonna with some angels round her, all very vivacious; and over a door of a little church near S. Piero Maggiore, in a lunette, he made another Madonna with some angels, which are held very beautiful. And in the Chapter-house of S. Croce, likewise, built by the family of the Pazzi under the direction of Pippo di Ser Brunellesco, he made all the glazed figures that are seen therein both within and without. And Luca is said to have sent some very beautiful figures in full-relief to the King of Spain, together with some works in marble. For Naples, also, he made in Florence the marble tomb for the infant brother of the Duke of Calabria, with many glazed ornaments, being assisted by his brother Agostino.
After these works, Luca sought to find a way of painting figures and scenes on a level surface of terra-cotta, in order to give long life to pictures, and made an experiment in a medallion which is above the shrine of the four saints without Orsanmichele, on the level surface of which, in five parts, he made the instruments and insignia of the Guilds of the Masters in Wood and Stone, with very beautiful ornaments. And he made two other medallions in the same place, in relief, in one of which, for the Guild of Apothecaries, he made a Madonna, and in the other, for the Mercatanzia, a lily on a bale, which has round it a festoon of fruits and foliage of various sorts, so well made, that they appear to be real and not of painted terra-cotta. In the Church of S. Brancazio, also, he made a tomb of marble for Messer Benozzo Federighi, Bishop of Fiesole, and Federighi himself lying on it, portrayed from nature, with three other half-length figures; and in the ornament of the pilasters of this work, on the level surface, he painted certain festoons with clusters of fruit and foliage, so lifelike and natural, that nothing better could be done in oil and on panel with the brush. Of a truth, this work is marvelous and most rare, seeing that Luca made the lights and shades in it so well, that it scarcely appears possible for this to be done by the action of fire. And if this craftsman had lived longer than he did, even greater works would have been seen to issue from his hands, since, a little before he died, he had begun to make scenes and figures painted on a level surface, whereof I once saw some pieces in his house, which lead me to believe that he would have easily succeeded in this, if death, which almost always snatches the best men away just when they are on the point of conferring some benefit on the world, had not robbed him of life before his time.
Luca was survived by Ottaviano and Agostino, his brothers, and from Agostino there was born another Luca, who was very learned in his day. Now Agostino, pursuing the art after the death of Luca, made the façade of S. Bernardino in Perugia in the year 1461, with three scenes in low-relief therein and four figures in the round, executed very well and with a delicate manner; and on this work he put his name in these words, AUGUSTINI FLORENTINI LAPICIDÆ.
Of the same family was the nephew of Luca, Andrea, who worked very well in marble, as it is seen in the Chapel of S. Maria delle Grazie, without Arezzo, where he made for the Commune, in a great ornament of marble, many little figures both in the round and in half-relief; which ornament was made for a Virgin by the
