More: Climate Activists Pour Oil On Gustav Klimt’s Death and Life At Leopold Museum In Vienna, Austria

Climate activists threw black liquid on the painting “Death and Life” by Gustav Klimt at the Leopold Museum in Austria on Tuesday. An activist with the Austrian branch of the German group Letzte Generation (Last Generation) squirted a black liquid over the painting, while another attempted to glue their hand to the paintings cover. They were quickly apprehended by security. “People still searching and drilling for new oil and gas have blood on their hands – and no amount of sponsoring will ever wash that blood off. There can be no clean art with dirty money involved,” the group tweeted after the stunt. The museum was free to the public Tuesday for St. Leopolds Day, and the event was sponsored by oil and gas company OMV. The museum said that there was “significant” damage to the protective glass cover over the painting and its frame, as well as the wall and floor. Leopold Museum Director Hans-Peter Wipplinger said in a statement that the activists concerns are valid, “but attacking artworks is definitely the wrong way to prevent the intended goal of preventing the projected climate collapse.” Last Generation is demanding legislation to lower speed limits to 100km/h, or about 62 mph, in order to reduce emissions. The stunt follows similar demonstrations by multiple climate groups at museums across Europe in recent months, including the defacement of Vincent van Goghs “Sunflowers” and Monets “Haystacks.”
