THEATRICAL MASK WITH DIONYSUS:Dionysus was the god of the grape harvest,winemaking and wine, of ritual madness and ecstasy in Greek mythology. His name in Linear B tablets shows he was worshipped c. 1500 1100 BC by Mycenean Greeks: other traces of Dionysian-type cult have been found in ancient Minoan Crete.His origins are uncertain, and his cults took many forms; some are described by ancient sources as Thracian, others as Greek.In some cults, he arrives from the east, as an Asiatic foreigner; in others, from Ethiopiain the South. He is a god of epiphany, “the god that comes”, and his “foreignness” as an arriving outsider-god may be inherent and essential to his cults. He is a major, popular figure of Greek mythology and religion, and is included in some lists of thetwelve Olympians. Dionysus was the last god to be accepted into Mt. Olympus. He was the youngest and the only one to have a mortal mother.His festivals were the driving force behind the development of Greek theatre.
