Sonia Delaunay (1885-1979, photo left) was born in the Ukraine, and later emigrated to Paris. She studied art at the Académie de La Palette in Montparnasse. However, it is said that she gained a deep appreciation of art and was able to explore the art movements of her time by visiting innumerable galleries in Paris. She married the French artist Robert Delaunay in 1910. Sonia is quoted as saying: "In Robert Delaunay I found a poet. A poet who wrote not with words but with colors."
The art movement called "modernism" in the early 20th century included a wide variety of creative explorations into the possibilities of abstract art. The type of abstraction found in Sonia Delalnay's work has a special name because of it's profound centering on dynamic color combinations. It was referred to as Orphism at a time when Cubism was centered on monochrome compositions. There is no clear explanation of why the name, except that Orpheus was a Greek god with musical charms. Music has a rapture that color has also, and certainly adds more passion to any abstract composition.
There are a few exceptions here — "Sleeping Girl" or "Ballet for the Four Seasons," but most of the titles, as regards the subject matter of Sonia Delaunay's work, simply refer to the painting's assembly of abstract or geometric forms, for instance, terms such as "composition," or "rhythm," also "mosaic," "pattern," or "color," as part of the title.
