The Sixty-fourth FIGURE.
A square Design in Perspective.
From the Plan and Upright in Perspective, this finish’d Piece of the whole Work is delineated after the usual Manner, and may serve for the Design of a great Altar in a Church. I have sometimes, for the Solemnity of the Forty Hours, expos’d this painted on a Machine, with an universal Satisfaction; Angels with Clouds possessing the higher part of the Hemisphere within, and Groups of Figures the lower part. The Manner of designing on the inner Frame, that part of the said Cupola which you here see, is deduc’d from what has been before said of putting Circles into Perspective.
