Drago Hrvacki is one of the key representatives of geometrism in Slovenian art. His approach to geometry was considered yet subtly poetic. He frequently used precise compositions of colour planes, lines and structures, thereby achieving visual tension and rhythmic harmony. For him, geometry was not merely a space of order, but a source of rational beauty and visual harmony. This first extensive exhibition of the artist's oeuvre brings together more than two hundred works, ranging from early objects, paintings and prints to drawings and sketches, which will be shown to the public for the first time.
