This scenery having also much pleased the Duke, he ordained, when the time came, that for his nuptials with Madama Margherita of Austria another comedy should be performed, with scenery by Aristotile, in the Company of Weavers, which is joined to the house of the Magnificent Ottaviano de' Medici, in the Via di S. Gallo. To which having set his hand with all the study, diligence, and labour of which he was capable, Aristotile executed all those preparations to perfection. Now Lorenzo di Pier Francesco de' Medici, having himself written the piece that was to be performed, had charge of the whole representation and the music; and, being such a man that he was always thinking in what way he might be able to kill the Duke, by whom he was so much favoured and beloved, he thought to find a way of bringing him to his end in the preparations for the play. And so, where the steps of the prospect-view and the floor of the stage ended, he caused the wing-walls on either side to be thrown down to the height of eighteen braccia, intending to build up in that space a room in the form of a purse-shaped recess, which was to be of considerable size, and a stage on a level with the stage proper, which might serve for the choral music. Above this first stage he wished to make another for harpsichords, organs, and other suchlike instruments that cannot be moved or changed about with ease; and the space where he had pulled down the walls, in front, he wished to have covered with curtains painted with prospect-views and buildings. All which pleased Aristotile, because it enriched the proscenium, and left the stage free of musicians, but he was by no means pleased that the rafters upholding the roof, which had been left without the walls below to support them, should be arranged otherwise than with a great double arch, which should be very strong; whereas Lorenzo wished that it should be sustained by some props, and by nothing else that could in any way interfere with the music. Aristotile, knowing that this was a trap certain to fall headlong down on a multitude of people, would not on any account agree in the matter with Lorenzo, who in truth had no other intention but to kill the Duke in that catastrophe. Wherefore, perceiving that he could not drive his excellent reasons into Lorenzo's head, he had determined that he would withdraw from the whole affair, when Giorgio Vasari, who was the protege of Ottaviano de' Medici, and was at that time, although a mere lad, working in the service of Duke Alessandro, hearing, while he was painting on that scenery, the disputes and differences of opinion that there were between Lorenzo and Aristotile, set himself dexterously between them, and, after hearing both the one and the other and perceiving the danger that Lorenzo's method involved, showed that without making any arch or interfering in any other way with the stage for the music, those rafters of the roof could be arranged easily enough.
