"Hasenblut" (1955) is a mixed media work by German artist Joseph Beuys that exemplifies his interest in organic materials and ritualistic performance. The piece incorporates actual animal blood along with other materials, reflecting Beuys's exploration of life, death, and transformation that would become central to his artistic practice. Created during a period of significant artistic and personal development, the work demonstrates his departure from traditional sculptural conventions toward a more conceptually driven and material based approach to art making.
