Yves Tanguy and Kay Sage were two of Surrealism's leading painters, who together elaborated de Chirico's world of isolate and obdurate forms into eerie landscapes sparsely populated with biomorphic life forms. Here, for the first time, the work of this dynamic couple is explored in depth. An essay by Stephen Robeson Miller examines the intersection of Sage's and Tanguy's biographies with their work, accurately recounting for the first time Sage's conversion to Surrealism. A second essay by Jonathan Stuhlman traces the ways in which Sage's art influenced Tanguy's. These essays are accompanied by color plates containing several previously unreproduced works and photographs.
