In 1976 Rudolf Sikora took the first steps into his exploration of a theme that would be at the core of his art for several years – the phenomenon of black holes, or the maximum possible concentration of energy. His cycles from the following years represented artistic parallels with this phenomenon. At first he concentrated signs (stars, crosses, arrows) into a single point, and later he manipulated photographs in order to achieve maximum visual concentration. The triptych Concentration of Energy applied a demanding collage technique in which Sikora used all the squares from a cut-up photograph. The triptych is an aptly chosen concept in which Sikora demonstrates how energy can be concentrated by conjoining initial elements.
