"The tongues of the envious were now silenced, and when the building was seen to proceed so happily, the genius of Filippo obtained its due consideration; and, by all who judged dispassionately, he was already held to have shown a boldness which has, perhaps, never before been displayed in their works, by any architect, ancient or modern. This opinion was confirmed by the fact that Filippo now brought out his model, in which all might see the extraordinary amount of thought bestowed on every detail of the building. The varied invention displayed in the staircases, in the provision of lights, both within and without, so that none might strike or injure themselves in the darkness, were all made manifest, with the careful consideration evinced by the different supports of iron which were placed to assist the footsteps wherever the ascent was steep. In addition to all this, Filippo had even thought of the irons for fixing scaffolds within the cupola, if ever they should be required for the execution of mosaics or pictures; he had selected the least dangerous positions for the places of the conduits, to be afterwards constructed for carrying off the rain water, had shown where these were to be covered and where uncovered; and had moreover contrived different outlets and apertures, whereby the force of the winds should be diminished, to the end that neither vapors nor the vibrations of the earth, should have power to do injury to the building: all which proved the extent to which he had profited by his studies, during the many years of his residence in Rome. When in addition to these things, the superintendents considered how much he had accomplished in the shaping, fixing, uniting, and securing the stones of this immense pile, they were almost awe-struck on perceiving that the mind of one man had been capable of all that Filippo had now proved himself able to perform. His powers and facilities continually increased, and that to such an extent, that there was no operation, however difficult and complex, which he did not render easy and simple; of this he gave proof in one instance among others, by the employment of wheels and counterpoises to raise heavy weights, so that one ox could draw more than six pairs could have moved by the ordinary methods. The building had now reached such a height, that when a man had once arrived at the summit, it was a very great labor to descend to the ground, and the workmen lost much time in going to their meals, and to drink; arrangements were therefore made by Filippo, for opening wine-shops and eating-houses in the cupola; where the required food being sold, none were compelled to leave their labor until the evening, which was a relief and convenience to the men, as well as a very important advantage to the work. Perceiving the building to proceed rapidly, and finding all his undertakings happily successful, the zeal and confidence of Filippo increased, and he labored
