Made in connection with Turner’s lectures as Professor of Perspective at the Royal Academy, this diagram of a head within a grid works along with another diagram (Tate D17106; Turner Bequest CXCV 135, and see also D16988; Turner Bequest CXCV 19) to illustrate anamorphic perspective. This method produces a distorted image that appears in natural form only when viewed at a special angle or reflected from a curved mirror.
