A fresco celebrating the fertility of Mt. Vesuvius’ volcanic soil. To the left stands Dionysus/Bacchus, covered in grape clusters. In the center is a snake, perhaps representing Ἀγαθὸς Δαίμων (“good spirit”), the tutelary deity or genius loci of the vineyards. Vesuvius itself looms in the background. From the “Casa del Centenario” at Pompeii; now in the National Archaeological Museum, Naples.
