Polykleitos

Polykleitos was an ancient Greek sculptor in bronze of the 5th century BC. Alongside the Athenian sculptors Pheidias, Myron and Praxiteles, he is considered one of the most important sculptors of classical antiquity. The 4th century BC catalogue attributed to Xenocrates (the "Xenocratic catalogue"), which was Pliny's guide in matters of art, ranked him between Pheidias and Myron. He is particularly known for his lost treatise (a canon of body proportions), the Canon of Polykleitos, setting out his mathematical basis of an idealised male body shape.
