1958-1959
Yvaral’s starting point was Vasarely’s optical research, but he opposed it by seeking to systematize the data involved. Even before the Groupe de Recherche d’Art Visuel, Yvaral produced a series of black-and-white paintings from which all subjective accident was excluded. A system presides over the elaboration of the surface, where each element maintains the same logical relationship with the whole. Progressions and permutations are developed with mathematical rigor.
