An elaborate modello for an arched altarpiece. The Madonna and Child enthroned beneath a baldacchino supported by putti; to the left, St Francis and St Clare; to the right, St Anthony of Padua and a kneeling bishop saint, pouring water from a jug onto the model of a city. To either side, partial views of a city, whose tower (to the left) seems to be the same as that in the model of the city below. 

The bishop saint was identified in a note on the mount (since erased; recorded by Popham) as St Prosdocimus, first bishop of Padua (cf. his statue, with a jug, by Donatello on the high altar at Padua). Popham queried whether his action would suggest the extinguishing of a city fire, though it could equally refer to the baptism of the inhabitants of a city. 

Though the drawing is squared for transfer, no corresponding painting is known. Inscribed in pencil in a hand of the eighteenth century, 'del Passignano'.
