'''Geometric abstraction''' is a form of [[abstract art]] based on the use of geometric forms sometimes, though not always, placed in [[Perspective (visual)|non-illusionistic]] space and combined into non-objective (non-representational) compositions. Although the genre was popularized by [[avant-garde]] artists in the early twentieth century, similar motifs have been used in art since ancient times.
