Dionysus-god of wine

Dionysus was the god of the grape harvest, winemaking and wine, of ritual madness and ecstasy in Greek mythology. Dionysus was the last god to be accepted into Mt. Olympus. His festivals were the driving force behind the development of Greek theatre. He is an example of a dying god. He was also known as Bacchus and the frenzy he induces, bakkheia. His thyrsus is sometimes wound with ivy and dripping with honey.
His cult is also a “cult of the souls”; his maenads feed the dead through blood-offerings, and he acts as a divine communicant between the living and the dead. He is a son of Zeus and the mortal Semele, thus semi-divine or heroic: and as son of Zeus and Persephone or Demeter, thus both fully divine, part-chthonic and possibly identical with Iacchus of the Eleusinian Mysteries.
