This work is based on a cast taken from the head of a living model named William Jeffrey. Casting from life involves encasing the sitter's head in wet plaster. After this has hardened, the resulting mould is taken apart in sections, and from this a cast in fibreclass is made. The advantage of this process is that an exact facsimile of the subject's features is obtained. Despite their precision, Davies has observed that life casts communicate little about the subject's character. Also, this realistic cast incorporates the strange addition of cones of chicken wire placed over the face. Consequently, this head does not characterise an individual, but represents human personality in general.
