The Marathon Boy bronze statue was discovered in 1925.
The sculpture, also called the Ephebe of Marathon, was recovered from the Aegean Sea in the Bay of Marathon in June 1925. It is now conserved in the National Archaeological Museum of Athens, where it is dated to approximately 340–330 BC.
The youthful figure is about 1.3 meters tall and is usually interpreted as an athlete, possibly a victor in an athletic competition. Its soft musculature, relaxed contrapposto, and raised arm have led scholars to associate it with the artistic tradition of Praxiteles. The original statue may have leaned against a column or another vertical support.
A common mix-up is the nearby date 1926, when the Artemision Bronze was discovered. The Marathon Boy is one of several important Greek bronzes recovered from Mediterranean waters, but its 1925 discovery helped draw attention to the preservation of ancient artworks underwater.
