Marble statue of the Diadoumenos (youth tying a fillet around his head)

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