In addition to his numerous internationally distributed sculptures, Eduardo Chillida created an extensive graphic oeuvre. Although there is a clear formal as well as content-related connection between prints and the sculptural work, Chillida did not regard his graphic works as sketches or preliminary drawings, but as independent works of equal value. The basic theme in his entire oeuvre is space, both physical space and spiritual and sensual space. Chillida is preoccupied with the contrast between matter and emptiness, whereby he also understands nothingness as space, the limited space enclosed by mass. The tension between solid material and the optical dissolution of the same becomes very visible in his graphic work. The graphics, all of which are in black and white, are characterised by their equally concrete and playful formal language and are also convincing because of their high aesthetic value.
