The so-called "Masturb@tor" of Pompeii is a plaster cast of a man who died during the catastrophic eruption of Mount Vesuvius in 79 AD. Though widely shared online with humorous claims that he was caught in an intimate act, experts explain that his posture is actually due to cadaveric spasm—a natural reaction where extreme heat causes sudden muscle contractions. The victim likely perished in a deadly pyroclastic surge, with intense heat forcing his limbs into a rigid, flexed position after death.
