used more generally to describe a person who is knowledgeable about the Orient, the term is also applied to 19th-century European painters and photographers of Near-Eastern scenes and their works of art. In 19th-century Europe, the word ‘Orient’ was primarily used for the areas bordering the Mediteranean that were under the Turkish or Ottoman Empire, as well as Morocco, Algeria and Tunisia. Orientalist works included images produced while travelling in the region as well as those produced in a studio with posed models and props.

The style – which developed out of cubism, with a tendency towards abstraction – focused on colour as the primary means of expression. See also abstract art.
