eureka max ernst grattage technique 2521464
The article explores how German Surrealist Max Ernst developed the techniques of frottage and grattage in the mid-1920s. Frottage—rubbing paper over textured surfaces like floorboards, leaves, and netting—allowed Ernst to create spontaneous, unconscious imagery, culminating in his 1926 publication *Natural History*. He later adapted the method to canvas as grattage, scraping layers of paint over textured materials to reveal abstract forms, drawing on influences from Leonardo da Vinci and memories of his childhood in the Rhineland.
