Myron

Myron of Eleutherae, working c. 480–440 BC, was an Athenian sculptor from the mid-5th century BC. He was born in Eleutherae on the borders of Boeotia and Attica. According to Pliny's Natural History, Ageladas of Argos was his teacher.
None of his original sculptures are known to survive, but there are many of what are believed to be later copies in marble, mostly Roman.
