always present difficulties in their execution; and if none ever did so before, this of vours does it to an extent of which you are not perhaps even yet fully aware, for I do not know that even the ancients ever raised so enormous a vault as this will be. I, who have many times reflected on the scaffoldings required, both within and without, and on the method to be pursued for working securely at this erection, have never been able to come to a decision; and I am confounded, no less by the breadth than the height of the edifice. Now if the Cupola could be arched in a circular form, we might pursue the method adopted by the Romans in erecting the Pantheon of Rome; that is, the Rotunda.[1] But here we must follow the eight sides of the building, dovetailing, and so, to speak, enchaining the stones, which will be a very difficult thing. Yet, remembering that this is a temple consecrated to God and the Virgin, I confidently trust, that for a work executed to their honour, they will not fail to infuse knowledge where it is now wanting, and will bestow strength, wisdom, and genius on him who shall be the author of such a project. But how can I help you in the matter, seeing that the work is not mine? I tell you plainly, that if it belonged to me, my courage and power would beyond all doubt suffice to discover means whereby the work might be effected without so many difficulties; but as yet I have not reflected on the matter to any extent, and you would have me tell you by what method it is to be accomplished. But even if your worships should determine that the cupola shall be raised, you will be compelled not only to make trial of me, who do not consider myself capable of being the sole adviser in so important a matter, but also to expend money, and to command that within a year, and on a fixed day, many architects shall assemble in Florence; not Tuscans and Italians only, but Germans, French, and of every other nation: to them it is that such an undertaking should be proposed, to the end that having discussed the matter and decided among so many masters, the work may be commenced and entrusted to him who shall give the best evidence of capacity, or shall display the best method and judgment for the execution of so great a
