Polykleitos was an ancient Greek sculptor in bronze of the 5th century BCE. His Greek name was traditionally Latinized Polycletus, but is also transliterated Polycleitus; (, "much-renowned") and due to iotacism in the transition from Ancient to Modern Greek, Polyklitos or Polyclitus. He is called Sicyonius (lit. "The Sicyonian", usually translated as "of Sicyon") by Latin authors including Pliny the Elder and Cicero, and Aργείος (lit. "The Argive", trans. "of Argos") by others like Plato and Pausanias. He is sometimes called the Elder, in cases where it is necessary to distinguish him from his son, a major architect but minor sculptor.
Alongside the Athenian sculptors Pheidias, Myron and Praxiteles, he is considered one of the most important sculptors of Classical antiquity. The 4th century BCE catalogue attributed to Xenocrates (the "Xenocratic catalogue"), which was Pliny's guide in matters of art, ranked him between Pheidias and Myron.
