Roman marble copies of Greek sculptures include two fine examples of the discus thrower — the complete Lancellotti Discobolus and the Discobolus of Castelporziona that has lost his head, an arm, and lower limbs. These copies are based on the original bronze by Myron, ca. 450 BC. Despite the difficulty of reproducing the discus thrower in marble, many copies were made during the Roman era with the two on display dating from the Hadrianic period (AD 117-138).
