 The Canon was not only a statue deigned to display perfect proportion, but a now-lost treatise on beauty. The physician Galen characterizes the text as specifying, for example, the proportions of “the finger to the finger, and of all the fingers to the metacarpus, and the wrist, and of all these to the forearm, and of the forearm to the arm, in fact of everything to everything…. For having taught us in that treatise all the symmetriae of the body, Polyclitus supported his treatise with a work, having made the statue of a man according to his treatise, and having called the statue itself, like the treatise, the Canon” (quoted in Pollitt 1974, 15). It is important to note that the concept of ‘symmetry’ in classical texts is distinct from and richer than its current use to indicate bilateral mirroring. It also refers precisely to the sorts of harmonious and measurable proportions among the parts characteristic of objects that are beautiful in the classical sense, which carried also a moral weight. For example, in the Sophist (228c-e), Plato describes virtuous souls as symmetrical.
