Bust of Dionysus

Dionysus the god of the grape-harvest, winemaking and wine, of fertility, ritual madness, religious ecstasy, and theatre in ancient Greek religion and myth. As Eleutherios (the liberator), his wine, music and ecstatic dance free his followers from self-conscious fear and care, and subvert the oppressive restraints of the powerful. Those who partake of his mysteries are believed to become possessed and empowered by the god himself. In his religion, identical with or closely related to Orphism, Dionysus was believed to have been born from the union of Zeus and Persephone, and to have himself represented a cthonic or underworld aspect of Zeus.
