Abstract art is to representative art what poetry is to prose. --Margaret PetersonThroughout her career, Peterson drew from many influences, especially from abstract and Indigenous artworks. In her early career, she was mainly influenced by
cubist and other
modernist artists. She has said that after seeing work by
Georges Braque and
Pablo Picasso, that “They changed my direction in art, and life”. She was also influenced by the Mexican artists
Carlos Mérida and
Rufino Tamayo, whom she had both met in
Mexico City in 1934. From these influences came her interest in form “as a symbol and a plastic constituent” and after 1949, as Colin Graham has said, her “main formal development after that date lay in her use of space, which became increasingly shallow." She was also known to mainly work in egg tempera instead of oil paints, especially after 1934, which was connected to her interest in Medieval European painting and mixed her colors through overlapping layers on her canvas instead of her palette. Besides formal elements, she was also greatly interested in spirituality and human spiritual beliefs and practices. To Peterson, formal elements were not only lines and colors on a canvas, but, as she has said, “Every line and every brush stroke is a vital related element to the total composition into which human thought has been transferred." On the topic of abstract art, she has said, “It is the act of man’s continual communion with the universe transformed as by magic into substance." From this interest, she was also greatly influenced by the art and practices of many Indigenous groups, who she saw as giving form to universal forces. It is in this way that she believed “art has been a summoning of those inexorable universal forces which man seeks but over which he has no control." == Exhibitions ==
