This collection of metal objects has the appearance of mysterious pieces of scientific apparatus, much like the items which appear in the artist's drawings of the 1950s and 1960s. The metals used here are iron and copper. Beuys saw iron as a masculine metal, connected with the planet Mars, while copper was associated with Venus and femininity. Part of the work was shown in the 'Zeitgeist' exhibition in Berlin in 1982, where Beuys had referred to it as a 'workshop' in which ideas for setting the world to rights could be fashioned.
