Writings on the Wall examines the significant influence of ancient and contemporary graffiti on the practice of a group of mid-twentieth-century artists, who studied the ways in which ideas and speech have been communicated and recorded through inscriptions on the communal walls of the urban environment. The exhibition includes works by Brassaï, Vlassis Caniaris, Jean Dubuffet, Manolo Millares, Antoni Tàpies and Cy Twombly. The artists selected for the exhibition share an interest in ghettoised or so-called derivative art forms, developed outside the structures of art institutions. They are connected by a specific focus on calligraphic gesture and textual writing and employ certain characters, signs and symbols to emulate a mutual graphic language used to express human experience.
