Rules and Examples of Perspective proper for Painters and Architects, etc. / In English and Latin: Containing a most easie and expeditious method to delineate in perspective all designs relating to architecture

by Andrea Pozzo

The Elevation of the Forty-first Figure in Perspective.

When the Parallels to the Ground-line in the Forty-third Figure, are prolong’d to the Visual TO, they are then, as usual, to be continu’d Parallels to the Perpendicular: On which Perpendicular, those Divisions given by Vignola, for the Proportions of this Order, are to be transferr’d; and Visuals drawn from them to the Point of Sight. How by these Visuals and Parallels the Elevation is rais’d in Perspective, is manifest in part from this Figure, but more clearly from the Forty-second Figure. The Numbers 1, 2, 3, 4, which you here see doubl’d, give the Centers and Heights of Semicircles of the Arches in the Forty-fifth Figure; the lower Numbers denoting the Centers, and the upper Numbers the Heights of the Semicircles of the same.
