Andrea, then, having found the work in this condition, distributed over these spaces, with a rich and beautiful arrangement, scenes from the life of the Madonna. In one of the two side-walls, he began in one part the Nativity of the Madonna, and executed half of it; and it was completely finished afterwards by Baccio Bandinelli. In the other part he began the Marriage of the Virgin, but this also remained unfinished, and after the death of Andrea it was completed as we see it by Raffaello da Montelupo. On the front wall he arranged that there should be made, in two small squares which are on either side of the bronze grating, in one the Visitation and in the other the scene of the Virgin and Joseph going to have themselves enrolled for taxes; which scenes were afterwards executed by Francesco da San Gallo, then a young man. Then, in that part where the greatest space is, Andrea made the Angel Gabriel bringing the Annunciation to the Virgin--which happened in that very chamber which these marbles enclose--with such grace and beauty that there is nothing better to be seen, for he made the Virgin wholly intent on that Salutation, and the Angel, kneeling, appears to be not of marble, but truly celestial, with "Ave Maria" issuing from his mouth. In company with Gabriel are two other Angels, in full-relief and detached from the marble, one of whom is walking after him and the other appears to be flying. Behind a building stand two other Angels, carved out by the chisel in such a way that they seem to be alive. In the air, on a cloud much undercut--nay, almost entirely detached from the marble--are many little boys upholding a God the Father, who is sending down the Holy Spirit by means of a ray of marble, which, descending from Him completely detached, appears quite real; as, likewise, is the Dove upon it, which represents the Holy Spirit. Nor can one describe how great is the beauty and how delicate the carving of a vase filled with flowers, which was made in this work by the gracious hand of Andrea, who lavished so much excellence on the plumes of the Angels, the hair, the grace of their features and draperies, and, in short, on every other thing, that this divine work cannot be extolled enough. And, in truth, that most holy place, which was the very house and habitation of the Mother of the Son of God, could not obtain from the resources of the world a greater, richer, or more beautiful adornment than that which it received from the architecture of Bramante and the sculpture of Andrea Sansovino; although, even if it were entirely of the most precious gems of the East, it would be little more than nothing in comparison with such merits.
