Thracian god, Bacchus - Bertrand Russell

Dionysus, or Bacchus, was originally a Thracian god. The Thracians were very much less civilized than the Greeks, who regarded them as barbarians. Like all primitive agriculturists, they had fertility cults, and a god who promoted fertility. His name was Bacchus. It was never quite clear whether Bacchus had the shape of a man or of a bull. When they discovered how to make beer, they thought intoxication divine, and gave honor to Bacchus. When, later, they came to know the vine and to learn to drink wine, they thought even better of him. His functions in promoting fertility in general became somewhat subordinate to his functions in relation to the grape and the divine madness produced by wine.
