An association of Spanish artists formed in Madrid in 1957. The name, meaning ‘crossing’ or ‘passage’, was meant to suggest movement or renewal. Its founding members were the painters Canogar, Luis Feito (1929– ), Millares, and Saura, together with the writers José Ayllón and Manuel Condé. They were soon joined by the painters Manuel Rivera (1927–1995) and Manuel Viola (1919–87) and the sculptor Martín Chirino (1925– ). The group, inspired by Dau al Set, was important in establishing expressive abstraction or Art Informel as a major idiom in Spanish art. In spite of official hostility, it held exhibitions until 1960.
