CASTEL, a large 24 x 30 cm, unpaginated book printed on chromo paper with an introduction by CASTEL Howard Morley SacharMichel Tapie de Celeyran and a study by Howard Morley Sachar. The book includes quotes by Julien Alvard, John Canaday, Sonia Delaunay, Haim Gamzu, Gerald Gassiot Talabot, Emily Genauer, Guy Habasque, Jacques Lasssaigne, Jean Jacques Leveque, Claude Riviere, Abram Leon Sachar, William C.Seitz, and Alfred Werner. The French texts were translated by Haakon Chevalier. There is a four page fold out entitled "Glory to Jerusalem" executed by the artist in 1968 after the large mural painting at the Knesset in Jerusalem (a partial reproduction appears on the book jacket). The elements of Castel's work include the magic of the paint quality intimately linked with that of the graphic design. His art can be described as "metaphysics of matter". He also composes signs going back to a calligraphic tradition giving the letter a type of magical existence. Castel's signs are often letters without any idea of a text and migled with invented signs, the sole aim to create structures and rhythms that are only artistic.
