The painting Ostrava Slag Heaps II is one of several variations on the subject. Zrzavý’s other works on a similar theme are in The Prague Municipal Gallery, The East Bohemian Gallery in Pardubice and in private collections. These steep idealised cones that are set in a stylised, mysteriously inhospitable and sinister setting sum up the heroic and tragic fate of that landscape. Zrzavý sketched those visions on the spot and the final work was created in his Paris studio, inspired by his own world of imagination.
