Picture theories are today a subject of broad interest to scholars, for the relationship between concept and picture, between thought and viewing, is among the commonest themes of the history of European thought, and already in Antiquity a multitude of solutions to the problem were discussed. The aim of this book is to elucidate the peculiarity of the relationship between viewing and concept analysed by Plato and Aristotle; to compare the theories of art and poetry initially conceived about 300BC, and which reached full development under the Roman Empire; and to expound modern concepts of viewing not only with forms of reception, but also the transformation of ancient theories of visual art.
