who were in his presence at the audience together with them. Whereupon Filippo spoke these words: "My Lords the Wardens, there is no doubt that great enterprises ever present difficulties in their execution, and if any ever did so, this of yours presents them, and even greater than perchance you are aware of, for the reason that I do not know whether even the ancients ever raised a vault so tremendous as this will be; and although I have often pondered over the framework necessary both within and without, and how it may be possible to work at it securely, I have never been able to come to any resolution, and I am aghast no less at the breadth than at the height of the edifice, for the reason that, if it could be made round, we might use the method used by the Romans in raising the dome over the Pantheon in Rome, that is, the Ritonda, whereas here we must follow the eight sides, and bind the stones together with ties and by dove-tailing them, which will be something very difficult. But remembering that this is a temple consecrated to God and to the Virgin, I am confident, since this is being done in memory of her, that she will not fail to infuse knowledge where it is lacking, and to give strength, wisdom, and genius to him who is to be the author of such a work. But how can I help you in this matter, since the task is not mine? I tell you, indeed, that if the work fell to me, I would have resolution and courage enough to find the method whereby the vault might be raised without so many difficulties; but as yet I have given no thought to it, and you would have me tell you the method! And when at last your Lordships determine to have it raised, you will be forced not only to make trial of me, for I do not think myself able to be the sole adviser in so great a matter, but also to spend money and to ordain that within a year and on a fixed day many architects shall come to Florence, not merely Tuscans and Italians, but Germans, French, and of every other nation; and to propose this work to them, to the end that, after discussing and deciding among so many masters, it may be begun, being entrusted to him who shall give the most direct proof of ability or possess the best method and judgment for such an undertaking. Nor could I give you other counsel or a better plan than this."
The plan and the counsel of Filippo pleased the Consuls and the Wardens of Works, but they would have liked him in the meanwhile to have made a model and to have given thought to the matter. But he showed that he cared nothing for it; nay, taking leave of them, he said that he had received letters soliciting him to return to Rome. Whereupon the Consuls, perceiving that their prayers and those of the Wardens did not avail to detain him, caused many of his friends to entreat him; but Filippo would not give way, and one morning (on May 26, 1417) the Wardens decreed him a present of money, which is found entered to the credit of Filippo in the books of the Office of Works; and all this was to conciliate him. But he, steadfast in his resolution, took his departure none the less from Florence and returned to Rome, where he studied continuously for that undertaking, making arrangements and preparing himself for the completion of the work, thinking, as was true, that no other than himself could carry it out. And as for his counsel that new architects should be summoned, Filippo had advanced it for no other reason but that they might serve to prove the greatness of his own intellect, and not because he thought that they would be able to vault that tribune or to undertake such a charge, which was too difficult for them. And thus much time was consumed before those architects arrived from their countries, whom they had caused to be summoned from afar by means of orders given to Florentine merchants who dwelt in France, in Germany, in England, and in Spain, and who were commissioned to spend any sum of money, if only they could obtain the most experienced and able intellects that there were in those regions from the Princes of those countries, and send them to Florence.
By the year 1420, all these ultramontane masters were finally assembled in Florence, and likewise those of Tuscany and all the ingenious craftsmen of design in Florence; and so Filippo returned from Rome. They all assembled, therefore, in the Office of Works of S. Maria del Fiore, in the presence of the Consuls and of the Wardens, together with a select body of the most ingenious citizens, to the end that these might hear the mind of each master on the question and might decide on a method of vaulting this tribune. Having called them, then, into the audience, they heard the minds of all, one by one, and the plan that each architect had devised for that work. And a fine thing it was to hear their strange and diverse opinions about the matter, for the reason that some said that piers must be built up from the level of the ground, which should have the arches turned upon them and should uphold the wooden bridges for sustaining the weight; others said that it was best to make the cupola of sponge-stone, to the end that the weight might be less; and many were agreed that a pier should be built in the centre, and that the cupola should be raised in the shape of a pavilion, like that of S. Giovanni in Florence. Nor were there wanting men who said that it would have been a good thing to fill it with earth mingled with small coins, to the end that, when it had been raised, anyone who wanted some of that earth might be given leave to go and fetch it, and thus the people would carry it away in a moment without any expense. Filippo alone said that it could be raised without so much wood-work, without piers, without earth, without so great expenditure on so many arches, and very easily without any framework.
It appeared to the Consuls, who were expecting to hear of some beautiful method, and to the Wardens of Works and to all those citizens, that Filippo had talked like a fool; and deriding him with mocking laughter, they turned away, bidding him talk of something else, seeing that this was the plan of a madman, as he was. Whereupon Filippo, feeling himself affronted, answered: "My Lords, rest assured that it is not possible to raise the cupola in any other manner than this; and although you laugh at me, you will recognize, unless you mean to be obstinate, that it neither must nor can be done in any other way. And it is necessary, if you wish to erect it in the way that I have thought of, that it should be turned with the curve of a quarter-acute arch, and made double, one vault within, and the other without, in such wise that a man may be able to walk between the one and the other. And over the corners of the angles of the eight sides the fabric must be bound together through its thickness by dove-tailing the stones, and its sides, likewise, must be girt round with oaken ties. And it is necessary to think of the lights, the staircases, and the conduits whereby the rain-water may be able to run off; and not one of you has remembered that you must provide for the raising of scaffoldings within, when the mosaics come to be made, together with an infinite number of difficulties. But I, who see the vaulting raised, know that there is no other method and no other way of raising it than this that I am describing." And growing heated as he spoke, the more he sought to expound his conception, to the end that they might understand it and believe in it, the greater grew their doubts about his proposal, so that they believed in him less and less, and held him to be an ass and a babbler. Whereupon, having been dismissed several times and finally refusing to go, he was carried away bodily from the audience by their servants, being thought to be wholly mad; and this affront was the reason that Filippo could afterwards say that he did not dare to pass through any part of the city, for fear lest someone might say: "There goes that madman."
The Consuls remained in the Audience Chamber all confused, both by the difficult methods of the original masters and by this last method of Filippo's, which they thought absurd, for it appeared to them that he would ruin the work in two ways: first, by making the vaulting double, which would have made it enormous and unwieldy in weight; and secondly, by making it without a framework. On the other hand, Filippo, who had spent so many years in study in order to obtain the commission, knew not what to do and was often tempted to leave Florence. However, wishing to prevail, he was forced to arm himself with patience, having insight enough to know that the brains of the men of that city did not abide very firmly by any one resolution. Filippo could have shown a little model that he had in his possession, but he did not wish to show it, having recognized the small intelligence of the Consuls, the envy of the craftsmen, and the instability of the citizens, who favoured now one and now another, according as it pleased each man best; and I do not marvel at this, since every man in that city professes to know as much in these matters as the experienced masters know, although those who truly understand them are but few; and let this be said without offence to those who have the knowledge. What Filippo, therefore, had not been able to achieve before the tribunal, he began to effect with individuals, talking now to a Consul, now to a Warden, and likewise to many citizens; and showing them part of his design, he induced them to determine to allot this work either to him or to one of the foreigners. Wherefore the Consuls, the Wardens of Works, and those citizens, regaining courage, assembled together, and the architects
