"Hasenblut (Hare's Blood)" is a mixed media work by German artist Joseph Beuys created in 1955 that combines various materials including paint, felt, and other substances on canvas. The work exemplifies Beuys's interest in unconventional materials and his belief in art's capacity to address spiritual and healing themes, particularly through his symbolic use of the hare as a figure of vulnerability and transformation. The piece reflects Beuys's broader artistic philosophy of expanding the definition of art beyond traditional media while engaging with personal and mythological narratives.
