Lettrism is an artistic style which was created in Romania by Isidore Isou in 1942, when he was only sixteen years old, according to Jean-Paul Curtay in La Poesie Lettriste (Paris1974). Lettrism was a response to what the Lettrists saw as André Breton's control of surrealism, as well as an attempt to make poetry more popular. The Lettrists worked in a variety of forms including sound as well as graphic arts involving letters.
Isou travelled to Paris where the Lettrist movement was formed. A split in the movement lead to the formation of the Lettrist International.
Lettrist works include Lexique Des Lettres Nouvelles, a sonic alphabet consisting of about 130 sounds which the Lettrists used in their poetry.
The film Irma Vep contains a sequence that evokes the Lettrist aesthetic...
