In front of such a complex and elusive personality, it is impossible to give just one interpretation of the character of Dionysos. From the third millennium BCE to the fall of the Roman Empire, the god constantly played a role – his figure was constantly shaped by societies, governments and people. As such, the interpretations offered by mythologists allow us to better understand Dionysos, but they will never be complete or exhaustive. As much, all they can do is bring to light some key elements of his being.
While the mythologists of the early 20th century were prone to excesses, the interpretations of names such as Frazer, Farnell or Miss Harrison are still very interesting. Dionysos is first and foremost a vegetation god, a fecundity god, a chthonian god. Many of his ceremonies are rituals celebrating renewal. He is a god of plants; his emblem if the thyrsus, a branch or a reed stalk crowned by leaves of ivy/vine, or by a pine cone. All these plants play a important role in both the rites and the myth of Dionysos, even though from the 7th century BCE onward he specializes himself as the god of the grapevine and of wine. Dionysos is the lord of the tree. As we saw before, he is related to the Oriental mother-goddesses and to the Aegean world. His wife is Ariadne – who might have been during the Classical era a human, but that was once an Aegean goddess of vegetation. Dionysos is the master of both animal and human fecundity – his favorite companions, the satyrs, the donkeys, the goats, the bulls, are all depicted with a very large phallus. He went down into the Underworld to bring back his mother Semele, and he presides over the Anthesteria, which was a celebration of the dead. Zagreus was believed to have for a mother Persephone, and for a father either Zeus or Hades – and in fact, Zagreus was sometimes identified as being an alternate identity of Hades. This chthonian side of Dionysos was developed in his mysteries: the initiation, the purifications, the teaches of sacred formulas have for a main purpose to allow the dead to escape all the dangers that threaten their travel to the afterlife ; and ultimately, to allow them to find happiness in the Hades.
