Polykleitos of Sikyon (Doryphoros or 'Canon')

Doryphoros or "Canon", 450 BC.
Polykleitos created this statue in order to support his published theoretical work "Canon" = "Rule", in which he was stating in mathematical terms the relationship of parts of the body with the whole, e.g. the proportion of finger with the palm, palm with wrist, wrist with elbow, elbow with arm. The proportion of the head with the body is one seventh (1/7).
Polykleitos is the first great aesthetician and his aim, in his own words, was to produce the "eu" = "the good, the perfect".
In his sculptures there is a dynamic counterbalance between the tensed and relaxed parts of the body.
In all his known works makes the body stand firmly on one foot, the other bending slightly in perfect rest, the so called "Chiastic" pose.
His objective is "Symmetria", a Greek word whose meaning is harmonious proportions.
