The Bacchae

The Bacchae, being from one point of view a religious drama, a kind of "mystery play," is full of allusions both to the myth and to the religion of Dionysus.

1. The Myth, as implied by Euripides. Semelê, daughter of Cadmus, being loved by Zeus, asked her divine lover to appear to her once in his full glory; he came, a blaze of miraculous lightning, in the ecstasy of which Semelê died, giving premature birth to a son. Zeus, to save this child's life and make him truly God as well as Man, tore open his own flesh and therein fostered the child till in due time, by a miraculous and mysterious Second Birth, the child of Semelê came to full life as God.
2. The Religion of Dionysus is hard to formulate or even describe, both because of its composite origins and because of its condition of constant vitality, fluctuation, and development.
(a) The first datum, apparently, is the introduction from Thrace of the characteristic God of the wild northern mountains, a God of Intoxication, of Inspiration, a giver of superhuman or immortal life. His worship is superposed upon that of divers old Tree or Veg- etation Gods, already worshipped in Greece. He becomes specially the God of the Vine. Originally a god of the common folk, despised and unauthorised, he is eventually so strong as to be adopted into the Olympian hierarchy as the "youngest" of the Gods, son of Zeus. His "Olympian" name, so to speak, is Dionysus, but in his worship he is addressed by numbers of names, more or less mystic and secret-Bromios, Bacchios or Baccheus, Iacchos, Eleuthercus, Za- greus, Sabazios, &c. Some of these may be the names of old spirits whom he has displaced; some are his own Thracian names. Bromos and Sabaja, for instance, seem to have been Thracian names for two kinds of intoxicating drink. Bacchos means a "wand." Together with his many names, he has many shapes, especially appearing as a Bull and a Serpent.
