Edited sentence: He also sculpted a famous bronze male nude known as the Doryphoros ("Spear-carrier"), which survives in the form of numerous Roman marble copies.Polykleitos consciously created a new approach to sculpture; he wrote a treatise (Kanon) and designed a male nude (also known as Kanon) exemplifying his aesthetic theories of the mathematical bases of artistic perfection, which motivated Kenneth Clark to place him among "the great puritans of art": His Kanon "got its name because it had a precise commensurability (symmetria) of all the parts to one another" "His general aim was clarity, balance, and completeness; his sole medium of communication the naked body of an athlete, standing poised between movement and repose" Kenneth Clark observed.Polykleitos' Astragalizontes ("Boys Playing at Knuckle-bones") was claimed by the Emperor Titus and set in a place of honour in his atrium.Though the Kanon may be represented by his Doryphoros, the bronze has not survived, but references to it in other ancient books imply that its main principle was expressed by the Greek words symmetria, the Hippocratic principle of isonomia ("equilibrium"), and rhythmos
