Heracles Labors: the Erymanthian Boar.
For his third labor, Heracles (Hercules) was charged with catching the boar that lived on Mount Erymanthus in Arcadia and bringing it back to Tiryns alive. He chased it into a field of snow, where it became exhausted, and captured it in a net.
In a parergon to this labor, Heracles battled Pholus.
