Precise design and an architectural approach are fundamental to the sculptures of Erwin Heerich, who created independent cardboard sculptures and also constructed the models of his buildings and free artworks in cardboard. The \u201cLichtdurchl\u00e4ssige B\u00fcndels\u00e4ule\u201d in front of the headquarters of the Federal Office of Administration in Cologne is a precisely calculated tower on a ground plan marked in dark floor tiles into which another square ground plan is inscribed. The tower itself is composed of prisms of the same height but different thickness facing each other which, in combination with the gaps between them, also form a square ground plan.<\/p>\n
The viewers trying to comprehend the relations between the various elements of the sculpture and its construction realise that their own movements as well as the role of the interstices and empty spaces are as important for the perception of the whole as the sculptural elements themselves.<\/p>\n","protected":false},"parent":0,"template":"","sculpture_city":[14652],"sculpture_epoch":[14684],"sculpture_artist":[15175],"sculpture_region":[15064],"sculpture_objecttype":[15555],"class_list":["post-32610","sculpture","type-sculpture","status-publish","hentry","sculpture_city-koeln","sculpture_epoch-1970er","sculpture_artist-erwin-heerich-en","sculpture_region-rheinschiene","sculpture_objecttype-sculpture"],"acf":{"location":"Barbarastr.
