This marble torso is an outstandingly well-preserved representation of an athletic male body in its prime. It is thought to be a Roman copy of an original by the Greek sculptor Polykleitos. The general style is of the fifth century BC, a period much favoured by Roman copyists. The fluid modelling is in the spirit of Polykleitos, who sought to represent the ideal proportions of the naked male body. It is more difficult, however, to pinpoint when the copy or adaptation was made.
