Description
Variant of Albrecht Dürer’s window described by Egnazio Danti in his commentaries to Vignola’s Le due regole [The two rules] and attributed to Don Girolamo da Perugia, Abbot of Lerino. Unlike its model, in which the points observed were fixed by two intersecting strings, this “window” determined the intersections of the visual ray by means of two small rods hinged to the ends of a board. The “window” with a sheet of drawing paper is hinged to the side of the board carrying the two rods. Keeping his eye on the sight, the painter looks at a point on the object to be drawn and positions the two rods to intersect at this point. He then raises the “window” and traces the intersection point on the drawing paper. This operation is then repeated for all of the significant points on the object.
