A design for one leaf of the great west door of Siena Cathedral (unexecuted). Peruzzi was in 1525 paid 250 lire and 5 soldi by the operai of the cathedral 'sonno per le sue fadighe di avere lui fatto piu disegni delle porti s'anno a fare di bronzo e per altri disegni' ['for his work in having made several drawings for the doors that are to be made in bronze, and for other drawings'].

The door is divided into three main rectangular spaces. In the top field is the Death of the Virgin; at the centre, the Visitation. A black chalk sketch in the lowest filed is hard to read but may be the Presentation/Circumcision. Two narrower fields depict Joesph sold to the Ishmaelites, and Joseph and Potiphar's Wife. The framing bands of the upper half of the design are filled with heads, standing figures and scrolling foliage.
