Dionysus ...was the god of the grape harvest, winemaking and wine, of ritual madness and ecstasy ...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. ... His festivals were the driving force behind the development of Greek theater. [Girard points out that Greek theatre replaced actual sacrifice with symbolic enactment, resulting in similar collective catharsis.]
The earliest cult images of Dionysus show a mature male, bearded and robed. He holds a fennel staff, tipped with a pine-cone and known as a thyrsus. Later images show him as a beardless, sensuous, naked or half-naked youth: the literature describes him as womanly or "man-womanish".[6] In its fully developed form,
his central cult imagery shows his triumphant, disorderly arrival or return, as if from some place beyond the borders of the known and civilized. His procession (thiasus) is made up of wild female followers (maenads) and ithyphallic [erect, therefore dangerous penii], bearded satyrs. Some are armed with the thyrsus, some dance or play music. The god himself is drawn in a chariot, usually by exotic beasts such as lions or tigers, and is sometimes attended by a bearded, drunken Silenus. ... Dionysus is represented by city religions as the protector of those who do not belong to conventional society and thus symbolizes everything which is chaotic, dangerous and unexpected, everything which escapes human reason and which can only be attributed to the unforeseeable action of the gods.[7]

The name Dionysos is of uncertain significance. The dio- element has been associated since antiquity with Zeus (genitive Dios): the -nysos element is cited as of unknown, possibly non-Greek origin. In Dionysiac tradition, the place of the god's childhood and education is called Nysa. Nisah is an epithet of the Hindu god Shiva, and means "supreme". "Nisam" is Sanskrit for bliss, nisâ, joy. Nysa, the Happy mountain, is the equivalent of Kailâsa, the Earthly Paradise, home of Shiva and his current wife, Parvati. [13] Dionysus and Shiva bear many resemblances other than name etymology, and aside from both being gods of love and ecstasy, namely, their association with the bull and the snake.

The cult of Dionysus was closely associated with trees, specifically the fig tree, and some of his bynames exhibit this, such as Endendros "he in the tree" or Dendritēs, "he of the tree". Peters suggests the original meaning as "he who runs among the trees", or that of a "runner in the woods"

Dionysus had a strange birth that evokes the difficulty in fitting him into the Olympian pantheon. His mother was a mortal woman, Semele, the daughter of king Cadmus of Thebes, and his father was Zeus, the king of the gods. Zeus' wife, Hera, discovered the affair while Semele was pregnant. Appearing as an old crone (in other stories a nurse), Hera befriended Semele, who confided in her that Zeus was the actual father of the baby in her womb. Hera pretended not to believe her, and planted seeds of doubt in Semele's mind. Curious, Semele demanded of Zeus that he reveal himself in all his glory as proof of his godhood. Though Zeus begged her not to ask this, she persisted and he agreed. Therefore he came to her wreathed in bolts of lightning; mortals, however, could not look upon an undisguised god without dying, and she perished in the ensuing blaze. Zeus rescued the fetal Dionysus by sewing him into his thigh. A few months later, Dionysus was born on Mount Pramnos in the island of Ikaria, where Zeus went to release the now-fully-grown baby from his thigh. In this version, Dionysus is born by two "mothers" (Semele and Zeus) before his birth, hence the epithet dimētōr (of two mothers) associated with his being "twice-born".

In the Cretan version of the same story, which Diodorus Siculus follows,[28] Dionysus was the son of Zeus and Persephone, the queen of the Greek underworld. Diodorus' sources equivocally identified the mother as Demeter.[29] A jealous Hera again attempted to kill the child, this time by sending Titans to rip Dionysus to pieces after luring the baby with toys. It is said that he was mocked by the Titans who gave him a thyrsus (a fennel stalk) in place of his rightful sceptre.[30] Zeus turned the Titans into dust with his thunderbolts, but only after the Titans ate everything but the heart, which was saved, variously, by Athena, Rhea, or Demeter. Zeus used the heart to recreate him in his thigh, hence he was again "the twice-born". Other versions claim that Zeus recreated him in the womb of Semele, or gave Semele the heart to eat to impregnate her.

According to the myth Zeus gave the infant Dionysus into the charge of Hermes. One version of the story is that Hermes took the boy to King Athamas and his wife Ino, Dionysus' aunt. Hermes bade the couple raise the boy as a girl, to hide him from Hera's wrath
