Olafur Eliasson’s immersive installation Your waste of time presents massive pieces of ice that broke off from Iceland’s largest glacier, Vatnajökull. The oldest ice in the glacier is estimated to have originated some 800 years ago, around AD 1200. Presented as sculptures that visitors can walk around and contemplate, their continued presence is made possible by refrigerating the gallery space to maintain a temperature below freezing. The physical experience of centuries-old ice from the glaciers of Eliasson’s native Iceland makes tangible a history that extends beyond the human life span—time that is measured in thousands of years rather than mere decades.
