Myron of Eleutherae (Μύρων, Myrōn mý.rɔːn), 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.
Myron worked almost exclusively in bronze and his fame rested principally upon his representations of athletes (including his iconic Diskobolos), in which he made a revolution, according to commentators in Antiquity, by introducing greater boldness of pose and a more perfect rhythm, subordinating the parts to the whole. Pliny's remark that Myron's works were numerosior than those of Polycleitus and "more diligent" seem to suggest that they were considered more harmonious in proportions (numeri) and at the same time more convincing in realism: diligentia connoted "attentive care to fine points", a quality that, in moderation, was characteristic of the best works of art, according to critics in Antiquity.
His most famous works according to Pliny's Natural History (34.57-59) were a heifer, a dog (canem, Cerberus?), a Perseus, a satyr (Marsyas) admiring the flute and Minerva (Athena), a Hercules, which was taken to the shrine dedicated by Pompey the Great at the Circus Maximus, Discobolus (the discus thrower), and an Apollo for Ephesus, "which Antony the triumvir took from the Ephesians, but the deified Augustus restored it again after being warned in a dream". The Early Imperial Roman writers consistently rated Myron among the greatest of Greek sculptors, a sign that his contemporaneous reputation had remained high. The heifer seems to have earned its fame mainly by serving as a peg on which to hang epigrams, which tell nothing about the pose of the animal.
Chionis, a 7th-century BC Olympic victor from Sparta, was commemorated in an idealized bronze by Myron.
