<P> The Discobolus of Myron ("discus thrower", Greek: Δισκοβόλος, Diskobólos) is a Greek sculpture completed at the start of the Classical Period, figuring a youthful ancient Greek athlete throwing discus, circa 460--450 BC . The original Greek bronze is lost but the work is known through numerous Roman copies, both full - scale ones in marble, which was cheaper than bronze, such as the first to be recovered, the Palombara Discobolus, and smaller scaled versions in bronze . </P> <P> A discus thrower depicted is about to release his throw: "by sheer intelligence", Kenneth Clark observed in The Nude, "Myron has created the enduring pattern of athletic energy . He has taken a moment of action so transitory that students of athletics still debate if it is feasible, and he has given it the completeness of a cameo ." The moment thus captured in the statue is an example of rhythmos, harmony and balance . Myron is often credited with being the first sculptor to master this style . Naturally, as always in Greek athletics, the Discobolus is completely nude . His pose is said to be unnatural to a human, and today considered a rather inefficient way to throw the discus . Also there is very little emotion shown in the discus thrower's face, and "to a modern eye, it may seem that Myron's desire for perfection has made him suppress too rigorously the sense of strain in the individual muscles," Clark observes . The other trademark of Myron embodied in this sculpture is how well the body is proportioned, the symmetria . </P>
