The artists Paul Klee (Berna, Switzerland, 1879-1940) and Mira Schendel (Zurich, Switzerland, 1919-1988) investigate the processes of form, conjugating materials and techniques that weave their own relations. The approximation of these two artists becomes possible through the understanding of Modernity and its correspondences with the other cultures and means of artistic expression. In different contexts, it is the critical aspect that prevails in these works, which privilege experimentation. In common, they have the line, non mediated by references to nature, which acts as an instrument in the search for a freer form, unfolding through space and time, and demanding the participation of the viewer.
