The Chapel of the Blessed Sacrament (Capello del Santissimo Sacramento), which houses the tabernacle, is also known as the Chapel of San Donato from a painting portraying the Madonna Enthroned between St. John the Baptist and St. Donatus (c. 1475-1486), on the right hand wall. The painting had been commissioned from Andrea del Verrocchio by the heirs of Donato de' Medici and was started by him but, left unfinished, was completed by Lorenzo di Credi. The bishop next to the Madonna has been identified as Saint Zeno. In the middle is the Assumption of the Virgin by Giovan Battista Paggi (1590-1600), while next to the entrance is the tomb of Donato de' Medici (1475), attributed to Antonio Rossellino.
