The malady with which I have had the misfortune to be attacked, might have deprived me of life, and put a stop to this work; wherefore, lest I should again fall sick, or Lorenzo either, which God forbid, I have considered that it would be better for each to execute his own portion of the work: as your worships have divided the salary, let us also divide the labour, to the end that each, being incited to show what he knows and is capable of performing, may proceed with confidence, to his own honour and benefit, as well as to that of the republic. Now there are two difficult operations which must at this time be put into course of execution—the one is the erection of scaffoldings for enabling the builders to work in safety, and which must be prepared both for the inside and outside of the fabric, where they will be required to sustain the weight of the men, the stones and the mortar, with space also for the crane to draw up the different materials, and for other machines and tools of various kinds. The other difficulty is the chain-work, which has to be constructed upon the twelve braccia already erected, this being requisite to bind and secure the eight sides of the cupola, and which must surround the fabric, enchaining the whole, in such a manner, that the weight which has hereafter to be laid on it shall press equally on all sides, the parts mutually supporting each other, so that no portion of the edifice shall be too heavily pressed on or over-weighted, but that all shall rest firmly on its own basis. Let Lorenzo then take one of these works, whichever he may think he can most easily execute, I will take the other and answer for bringing it to a successful conclusion, that we may lose no more time.” Lorenzo having heard this, was compelled, for the sake of his honour, to accept one or other of these undertakings; and although he did it very unwillingly, he resolved to take the chain-work, thinking that he might rely on the counsels of the builders, and remembering also that there was a chain-work of stone in the vaulting of San Giovanni di Fiorenza, from which he might take a part, if not the whole, of the arrangement. One took the scaffolds in hand accordingly, and the other the chain-work, so that both were put in progress. The scaffolds of Filippo were constructed with so much ingenuity and
