In his works, Hopper poetically expressed the solitude of man confronted with the American way of life as it developed in the 1920s. Inspired by the movies and particularly by the various camera angles and attitudes of characters, his paintings expose the alienation of mass culture. Done in cold colours and inhabited by anonymous characters, Hopper▓s paintings also symbolically reflect the Great Depression. Through a series of different reproductions (etchings, watercolours, and oil-on-canvas paintings), as well as thematic and artistic analysis, the author sheds new light on the enigmatic and tortured world of this outstanting figure.
