His early works are the terra cotta altarpiece in Santa Chiara at Monte San Savino, and the marble reliefs of the Annunciation, the Coronation of the Virgin, a Pietà, the Last Supper, and various statuettes in the Corbinelli chapel of Santo Spirito at Florence, all executed between the years 1488 and 1491.
The beginning of a more pagan style is shown in the St. John Baptizing Christ statues over the east door of the Battistero di San Giovanni in Florence (1505).
The architectural parts of these monuments and their sculptured foliage are extremely graceful and executed with the most minute delicacy, but the recumbent effigies show the beginning of a serious decline in taste.
[1] In 1512, while still in Rome, Sansovino executed a very beautiful group of the Madonna and Child with St. Anne, now over one of the side altars in the church of Sant'Agostino.
From 1513 to 1528 he was at Loreto, where he cased the outside of the Santa Casa in white marble, covered with reliefs and statuettes in niches between engaged columns; a small part of this sculpture was the work of Andrea, but the greater part was executed by Raffaello da Montelupo, Tribolo and others of his assistants and pupils.
