The treachery of images is a concept famously illustrated by the Belgian Surrealist artist René Magritte, particularly in his painting 'The Treachery of Images,' which features the text 'Ceci n'est pas une pipe' (This is not a pipe). This phrase challenges viewers to reconsider the relationship between representation and reality, highlighting that images are mere symbols and not the objects they depict. This idea plays a significant role in Surrealism, where the exploration of dreams, the subconscious, and the bizarre often blurs the line between reality and illusion.
