The Subiaco Ephebe (or the Youth from Subiaco) is a sculpture of a young man approaching puberty found on the site of the Neronian Villa Sublaquensis at Subiaco (Roman Sublaqueum) in the upper Aniene valley, Lazio, Italy. The headless marble is a copy of a lost Greek bronze, as evidenced by an awkward tree-trunk support and "the failure of the total silhouette to keep manageably within the boundaries of a single block of stone", as Rhys Carpenter observes; it is unlikely to postdate Nero because of its find location. The date of the bronze original that it reflects is contested. When it was first found August Kalkmann gave it a date early in the fifth century BCE. but general opinion before World War II made it a work of the end of the fourth century in the turn towards Hellenistic style,
