Description
Pietro Accolti’s perspective instrument is a variant of Albrecht Durer’s more famous window. Unlike its model, Accolti’s instrument could be used to depict from real life objects situated at any distance. The visual ray was not, in fact, simulated by a string. The painter looks at a point on the object through a viewer and intersects the visual ray by mans of a ball sliding on a string that runs diagonally across the frame of the “window”. When the ball is stopped at the point sighted, the “window” is closed and the position of the ball is transcribed onto the sheet of drawing paper. A variant of this instrument, with the “window” hinged to the base of the frame, was proposed later by William Halfpenny in 1731.
