This drawing relates to an 'action' of February 1963 called 'Siberian Symphony, Section I'. As part of the performance, the artist tore the heart from a dead hare and hung the animal on a blackboard. Lumps of clay were connected with wires, as can be seen to the right of this image. The shape at the bottom of the drawing is a grand piano with its lid up, an item also used in the performance. Beuys had been introduced to performance art by the Fluxus group and this was one of his first public performances, or 'actions'. It was performed for the 'Festum Fluxorum Fluxus' at Düsseldorf Academy, where Beuys taught as professor of sculpture.
