Fauvism is considered the first avant-garde art movement of the 20th century. It got its name in 1905, and it lived for only a couple of years, then each of the artists who called themselves the Fauves went deep into own creative search. The brightest representatives of the Fauvism are Henri Matisse , André Derain and Maurice de Vlaminck .
Op art (optical art) is one of the branches of mid-20th-century geometric abstract art that deals with optical illusion. Representatives of this style sought to create on a flat surface the illusion of movement through the use of colour contrasts and geometric patterns. The most prominent representatives of Op art are Victor Vasarely, Bridget Riley, Julian Stanczak and Carlos Cruz-Diez.
