Looking inside the two boxes in this vitrine, we can see that in one, the fat has been neatly shaped into the corner to make a wedge. In the other, the shape of the fat has a disturbing biological look to it, like inner organs which have been unceremoniously dumped in a heap. Beuys used triangles of fat in both his sculptures and 'actions'. From around 1963, he would use wedges of fat or felt to mark the boundaries of a space when performing an 'action'.
