At the margins of the French lettriste movement as he knew Isou and Dufrene, Altagor (pseudonym of Jean Vernier1915-1982) formerly a mechanic and miner, then writer of thrillers, created 'Métapoésie' poetry composed of invented words, therefore abstract. Also an instrument builder, he accompanied his poetry readings on the pantophone, a stringed, bowed instrument. -- Source of annotation: Marvin or Ruth Sackner.
