On Monday, a fresco titled "Young Hercules and the Snake" from Herculaneum was returned to Italy along with 59 other ancient pieces that had been illegally trafficked to the United States. The returned works are estimated to be worth more than $20 million and are a major victory for Italy in its fight against international art trafficking. The pieces were originally from Herculaneum, a city destroyed by the 79 A.D. eruption of Mount Vesuvius.
