Forward Retreat, 1986, describes the slipperiness of perception and questions the validity of innovation in art. The central image of horseback riders is painted as a reflection on water. The riders, all outfitted in uniforms of Western powers (American, French, German, and British), represent the nationalities of artists who came to dominate 20th-century art history. They are seated backward on their horses, focused on a distant receding horizon, and are oblivious to the fact that their steeds trample on the crushed ruins of myriad pottery and objets d’art. With typically dry humor, Tansey implies two conclusions: that art progresses on the ruins of its past and that art making is propelled in part by unconscious forces.
