Abstract
This paper addresses what is arguably ?? one of the most fundamental questions in the debate on depiction, What is a Picture? It offers a critical discussion of traditional theories of pictorial representation, such as the Resemblance Theory, Conventionalism, and the Illusion Theory; it introduces and analyses the crucial notions of ‘seeing as’ and ‘seeing in’, and concludes by presenting some of the most recent accounts of depiction defended by Kendall Walton, Dominic Lopes, Robert Hopkins, and John Hyman.
