Klearchos Loukopoulos was one of the most important representatives of non-figurative sculpture in Greece. He started with realistic depiction, during the years between the wars, but soon turned toward more abstract forms, guided by archaic sculpture. 1955-1960 was a transitional period for him since he abandoned the use of stone and marble and turned to iron, making compositions on the border between the figurative and the abstract, inspired by Mycenean art. His steady course toward complete abstraction reached its peak at the beginning of the Sixties when he abandoned representational work once and for all. The artist’s constant quest for new expressive methods led him to compositions based on assemblage of chance materials made of iron, while after 1970 his works acquired a constructivist character. “Superimposition” comes from that period and is the continuation of a series of compositions based on polyhedric volumes scattered in space, or assembled rhythmically in constructivist constructions, with a strong sense of balance and a latent motion which arises from the assemblage of the separate elements.
