The principal entrance at the center of the portico is surmounted by a lunette fanlight. A radial fanlight filled the lunette above the transom. Above the door is a simple, well-defined semicircular lunette adorned with pinions. Two preparatory studies for the lunette paintings are preserved in the Louvre. Similar frames surround the lunette panels of Raffaello Vanni above the tombs. A pair of angels, holding a medallion with a cross, crowns each lunette. In the lunette above is a bas-relief of the Madonna and Child. The Marquis de Montbrun commanded the main effort against the lunette. Granbury's Lunette was well masked by trees and brush. Baldovinetti painted the first lunette in the chiostro in c. 1460. His name was written in Luwian hieroglyphs with a lunette. The far left lunette shows the prophet Zechariah and the far right one shows Micah. The Cerasi coat-of-arms is depicted in the center of the stained glass lunette window. The upper one consisted of a round lunette. On top of the lunette stands the figure of the Father Creator.
