Here is some text from Tate Britain's website: Angel of Anarchy is a sculpture by the Argentine-born British artist Eileen Agar. It comprises a plaster cast head covered with found materials and objects such as embroidered silk fabric, feathers, sea-shells, African beads and diamante stones. While some of the elements suggest facial features, others seem more like decorative accessories or jewellery. At times they could be read as either: for instance, feathers could be errant tufts of hair or part of an elaborate headdress. Similarly, the patterned fabric serves as skin for the face as well as a blindfold. This ambiguity creates allusions to seduction and submissiveness, although the accumulation of elements also appeals to the anarchy referenced in the title. Angel of Anarchy is displayed on top of a white pedestal under a protective Perspex case due to its fragile condition.
The work was created by Agar in 1936–40. Agar was a friend of Henry Moore and she would accompany him on visits to the ethnographic collections at the British Museum in London, whose collection of African sculpture influenced both artists. In contrast to Moore, Agar worked primarily in plaster, which she chose because ‘bronze was too expensive’. In addition, rather than making preliminary drawings, Agar used found materials, applying them directly onto the head. The white plaster cast in this sculpture is from a modelled clay bust of the artist’s future husband Joseph Bard.
