From the term anamorphoses, which is derived from the Greek words “ana” (again), and “morphe” (shape) and means a distorted image.
The observer is first deceived by a barely recognizable image, and is then directed to a viewpoint dictated by the formal construction of the painting. The spectator must play a part and re-form the picture him/herself.
Similar characteristics can be found in illusionistic wall and ceiling painting, and in the use of accelerated and retarded perspective in architecture, theatrical stage design, and urban design.
