Dionysus was a greek god of fertility, and wine later considered a Patron of the arts. He created wine and spread the art of viticulture. He had a dual nature: on one hand, he brought joy and ecstasy, or he would bring brutal, and blinding rage, thus reflecting the dual nature of wine. Dionysus could not be found by fetters. Dionysus was the son Zeus and Semele, and was the only god with a mortal parent.
