that he is ill?" The Wardens of Works, seeing themselves disgraced by this state of things, determined to go and find Filippo; and after arriving and sympathizing with him first about his illness, they told him in how great confusion the building stood and what troubles his illness had brought upon them. Whereupon Filippo, speaking with great heat both under the cloak of illness and from love of the work, replied, "Is not that Lorenzo there? Can he do nothing? And I marvel at you as well." Then the Wardens answered, "He will do naught without thee"; and Filippo retorted, "But I could do well without him." This retort, so acute and double-edged, was enough for them, and they went their way, convinced that Filippo was ill from nothing but the desire to work alone. They sent his friends, therefore, to get him out of bed, with the intention of removing Lorenzo from the work. Wherefore Filippo returned to the building, but, seeing that Lorenzo was still strongly favoured and that he would have his salary without any labour whatsoever, he thought of another method whereby he might disgrace him and demonstrate conclusively his little knowledge in that profession; and he made the following discourse to the Wardens in the presence of Lorenzo: "My Lords the Wardens of Works, if the time that is lent to us to live were as surely ours as the certainty of dying, there is no doubt whatsoever that many things which are begun would be completed instead of remaining unfinished. The accident of this sickness from which I have suffered might have cut short my life and put a stop to the work; wherefore I have thought of a plan whereby, if I should ever fall sick again, or Lorenzo, which God forbid, one or the other may be able to pursue his part of the work. Even as your Lordships have divided the salary between us, let the work also be divided, to the end that each of us, being spurred to show his knowledge, may be confident of acquiring honour and profit from our Republic. Now there are two most difficult things which have to be put into execution at the present time: one is the making of the scaffoldings to enable the masons to do their work, which have to be used both within and without the building, where they must support men, stones, and lime, and sustain the crane for lifting weights, with other instruments of that kind; the other is the chain of ties which has to be placed above the twelve braccia, surrounding and binding together the eight sides of the cupola, and clamping the fabric together, so that it may bind and secure all the weight that is laid above, in such a manner that the weight may not force it out or stretch it, and that the whole structure may rest firmly on its own basis. Let Lorenzo, then, take one of these two works, whichever he may think himself best able to execute; and I will undertake to accomplish the other without difficulty, to the end that no more time may be lost." Hearing this, Lorenzo was forced for the sake of his honour to accept one of these tasks, and, although he did it very unwillingly, he resolved to take the chain of ties, as being the easier, relying on the advice of the masons and on the remembrance that in the vaulting of S. Giovanni in Florence there was a chain of stone ties, wherefrom he might take a part of the design, if not the whole. And so one put his hand to the scaffoldings and the other to the ties, and each carried out his work. The scaffoldings of Filippo were made with so great ingenuity and industry, that the very opposite opinion was held in this matter to that which many had previously conceived, for the builders stood on them, working and drawing up weights, as securely as if they had been on the surface of the ground; and the models of the said scaffoldings were preserved in the Office of Works. Lorenzo had the chain of ties made on one of the eight sides with the greatest difficulty; and when it was finished, the Wardens caused Filippo to look at it. To them he said nothing, but he discoursed thereon with some of his friends, saying that it was necessary to have some form of fastening different from that one, and to apply it in a better manner than had been done, and that it was not strong enough to withstand the weight that was to be laid above, for it did not bind the masonry together firmly enough; adding that the supplies given to Lorenzo, as well as the chain that he had caused to be made, had been simply thrown away. The opinion of Filippo became known, and he was charged to show what was the best way of making such a chain. Whereupon, having already made designs and models, he immediately showed them, and when they had been seen by the Wardens and the other masters, it was recognized into what great error they had fallen by favouring Lorenzo; and wishing to atone for this error and to show that they knew what was good, they made Filippo overseer and superintendent of the whole fabric for life, saying that nothing should be done in that work without his command. And as a proof of approbation they gave him one hundred florins, decreed by the Consuls and Wardens under date of August 13, 1423, by the hand of Lorenzo Paoli, notary to the Office of Works, and under the name of Gherardo di Messer Filippo Corsini; and they voted him an allowance of one hundred florins a year as a provision for life. Wherefore, giving orders for the building to be pushed on, he pursued it with such scrupulous care and so great attention, that not a stone could be put into place without his having wished to see it. Lorenzo, on the other hand, finding himself vanquished, and, as it were, put to shame, was favoured and assisted by his friends so powerfully that he went on drawing his salary, claiming that he could not be dismissed until three years had passed.
Filippo was for ever making, on the slightest occasion, designs and models of stages for the builders and of machines for lifting weights. But this did not prevent certain malicious persons, friends of Lorenzo, from putting Filippo into despair by spending their whole time in making models in opposition to his, insomuch that some were made by one Maestro Antonio da Verzelli and other favoured masters, and were brought into notice now by one citizen and now by another, demonstrating their inconstancy, their little knowledge, and their even smaller understanding, since, having perfection in their grasp, they brought forward the imperfect and the useless.
The ties were now finished right round the eight sides, and the masons, being encouraged, were labouring valiantly; but being pressed more than usual by Filippo, and resenting certain reprimands received with regard to the building and other things that were happening every day, they had conceived a grievance against him. Wherefore, moved by this and by envy, the foremen leagued themselves together into a faction and declared that the work was laborious and dangerous, and that they would not build the cupola without great payment—although their pay had been raised higher than usual—thinking in this way to take vengeance on Filippo and to gain profit for themselves. This affair displeased the Wardens and also Filippo, who, having pondered over it, made up his mind one Saturday evening to dismiss them all. They, seeing themselves dismissed and not knowing how the matter would end, were very evilly disposed; but on the following Monday Filippo set ten Lombards to work, and by standing ever over them and saying, "Do this here," and, "Do that there," he taught them so much in one day that they worked there for many weeks. The masons, on the other hand, seeing themselves dismissed, deprived of their work, and thus disgraced, and having no work as profitable as this, sent mediators to Filippo, saying that they would willingly return, and recommending themselves to him as much as they were able. Filippo kept them for many days in suspense as to his willingness to take them back; then he reinstated them at lower wages than they had before; and thus where they thought to gain they lost, and in taking vengeance on Filippo they brought harm and disgrace on themselves.
The murmurings were now silenced, and meanwhile, on seeing that building being raised so readily, men had come to recognize the genius of Filippo; and it was already held by those who were not prejudiced that he had shown such courage as perchance no ancient or modern architect had shown in his works. This came to pass because he brought out his model, wherein all could see how much thought he had given to the planning of the staircases and of the lights both within and without, in order that no one might be injured in the darkness by reason of fear, and how many diverse balusters of iron he had placed where the ascent was steep, for the staircases, arranging them with much consideration. Besides this, he had even thought of the irons for fixing scaffoldings within, in case mosaics or paintings had ever to be wrought there; and in like manner, by placing the different kinds of water-conduits, some covered and some uncovered, in the least dangerous positions, and by duly accompanying these with holes and diverse apertures, to the end that the force of the winds might be broken and that neither exhalations nor the tremblings of the earth might be able to do any harm, he showed how great assistance he had received from his studies during the many years that he stayed in Rome. And in addition, when men considered what he had done in the way of dove-tailing, joining, fixing, and binding together
