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
