To commemorate the centennial of the death of Edgar Degas (1834-1917), through Sunday the musée d’Orsay has organized an exhibition that juxtaposes paintings, pastels, and drawings from the Impressionist artist and others with “Degas Danse Dessin,” published in 1936 by the art dealer Ambroise Vollard. Accompanied by 26 hors-textes reproductions of Degas’s graphic work, the luxury edition was written by French poet Paul Valéry (1871-1945). “There’s an immense difference between seeing something without the pencil in hand, and seeing it in drawing it,” Valéry observed. “Or rather, one sees two different things. Even the most familiar object to our eyes becomes something completely different, if one proceeds to draw it; we realize that… we never really saw it.” Edgar Degas (1834-1917), “Dancer.” Drawing featured in Paul Valéry’s “Degas Danse Dessin,” published by Ambroise Vollard in 1936.
