Ancient Egyptian art and Mesopotamian art often featured composite perspectives, blending different viewpoints into a single scene to communicate symbolic or hierarchical meaning.

An art movement is a tendency or style in art with a specific art philosophy or goal, followed by a group of artists during a specific period of time, (usually a few months, years or decades) or, at least, with the heyday of the movement defined within a number of years.
The originator of the term was the French art critic Jules-Antoine Castagnary, who in 1863 announced that: "The naturalist school declares that art is the expression of life under all phases and on all levels, and that its sole aim is to reproduce nature by carrying it to its maximum power and intensity: it is truth balanced with science".
Distortion occurs when the transfer function F is more complicated than this. If F is a linear function, for instance a filter whose gain and/or delay varies with frequency, the signal suffers linear distortion. Linear distortion does not introduce new frequency components to a signal but does alter the balance of existing ones.
The definition of Mannerism and the phases within it continue to be a subject of debate among art historians. For example, some scholars have applied the label to certain early modern forms of literature (especially poetry) and music of the 16th and 17th centuries.

A classical example for a physical distortion would be the apparent bending of a stick half immersed in water; an example for a physiological paradox is the motion aftereffect (where, despite movement, position remains unchanged). [4] An example for a physiological fiction is an afterimage. [4]
