The Surrealist circle was made up of many of the great artists of the 20th century, including Max Ernst, Giorgio de Chirico, Jean Arp, Man Ray, Joan Miro, and Rene Magritte. Salvador Dali, probably the single best-known Surrealist artist, broke with the group due to his right-wing politics (during this period leftism was the fashion among Surrealists, and in fact in almost all intellectual circles).
