A series that began in Paris in 1984, the drawings are all completed using a technical pen on paper, but have been shown in many different forms — as paintings on a wall, in large-scale installations, videos and books. All share the same basic idea of lines interacting in an ongoing process, a process that will only stop with the death of its maker. Le Songe Creux — Codex brings this process into a Chinese ‘butterfly’ book format: a more portable version (half-size) of a large-scale drawing. The two books, accordion- and scroll-like, measure 4200mm long on each side. The open space accords with the artist’s ideas of process and continuity much more than the constantly interrupted division of pages of a typical modern book.
