At that time Vasari was with Michelagnolo every day; and one morning the Pope in his kindness gave them both leave that they might visit the Seven Churches on horseback (for it was Holy Year), and receive the Pardon in company. Whereupon, while going from one church to another, they had many useful and beautiful conversations on art and every industry, and out of these Vasari composed a dialogue, which will be published at some more favourable opportunity, together with other things concerning art. In that year Pope Julius III confirmed the Motu-proprio of Pope Paul III with regard to the building of S. Pietro; and although much evil was spoken to him of Michelagnolo by the friends of the San Gallo faction, in the matter of that fabric of S. Pietro, at that time the Pope would not listen to a word, for Vasari had demonstrated to him (as was the truth) that Michelagnolo had given life to the building, and also persuaded his Holiness that he should do nothing concerned with design without the advice of Michelagnolo. This promise the Pope kept ever afterwards, for neither at the Vigna Julia did he do anything without his counsel, nor at the Belvedere, where there was built the staircase that is there now, in place of the semicircular staircase that came forward, ascending in eight steps, and turned inwards in eight more steps, erected in former times by Bramante in the great recess in the centre of the Belvedere. And Michelagnolo designed and caused to be built the very beautiful quadrangular staircase, with balusters of peperino-stone, which is there at the present day. Vasari had finished in that year the printing of his work, the Lives of the Painters, Sculptors, and Architects, in Florence. Now he had not written the Life of any living master, although some who were old were still alive, save only of Michelagnolo; and in the book were many records of circumstances that Vasari had received from his lips, his age and his judgment being the greatest among all the craftsmen. Giorgio therefore presented the work to him, and he received it very gladly; and not long afterwards, having read it, Michelagnolo sent to him the following sonnet, written by himself, which I am pleased to include in this place in memory of his loving-kindness: Se con lo stile o co' colori havete Alla Natura pareggiato l'Arte, Anzi a quella scemato il pregio in parte, Che 'l bel di lei più bello a noi rendete, Poichè con dotta man posto vi siete A più degno lavoro, a vergar carte, Quel che vi manca a lei di pregio in parte, Nel dar vita ad altrui tutto togliete. Che se secolo alcuno omai contese In far bell'opre, almen cedale, poi Che convien', ch'al prescritto fine arrive. Or le memorie altrui già spente accese Tornando fate, or che sien quelle, e voi, Mal grado d'esse, eternalmente vive.
