Text, Art and Audiences

Text has been used as a communication tool in artwork for many years. Some examples of this include: Magritte’s famous painting pipe painting Treachery of Images, the numerous comic strip styled artworks of Roy Litchenstein, the enormous collection of text based artworks by Jenny Holzer, and eco-artist David Buckland’s recent Ice Texts. But why do artist's put text in art? What is it that drives this need for communication with the audience of an artwork via not just image or colour or process but also words?
