Joseph Beuys created this work as a conceptual engagement with Leonardo da Vinci's Madrid Codices, the Renaissance master's notebooks rediscovered in the 1960s. Through his characteristic mixed media approach, Beuys responded to Leonardo's scientific and artistic investigations, creating a dialogue across centuries between two visionary thinkers. The work exemplifies Beuys' belief that art could activate human creativity and expand the boundaries of what constitutes artistic practice.
