Cy Twombly, born in Lexington, Virginia, in 1928, entered the stage of contemporary art with his drawings. His nervous line making distinguished him from all his colleagues who in the 50s and 60s were involved in Abstract Expressionism. His tumbling and nervous markings opened new psychological spaces to a personal and very conceptual art. At first mistaken for something between graffiti and criture auto matique, Cy Twombly s graphic notes eventually transformed into huge canvases of paintings in which he incorporated these notes as a maelstrom of emotional states. The Catalogue Raison of the Drawings and Sketchbooks edited by Nicola Del Roscio will be published in five volumes. The first volume contains the drawings of the years 1951 to 1955.
