History
Dionysiac
In every Greek city the god Dionysus was worshipped by fraternities and sororities and also by mixed communities. Dionysus was a god of fruitfulness and vegetation but especially of wine. The Dionysiac festivals provided an opportunity for stepping outside of the daily routine. The festivals included not only drinking wine and engaging in sexual activity but also participating in such significant features of Greek civilization as choral singing and mimes. In many cases, only the initiated could participate in the ceremonies. As almost every Greek did join in, initiation into the Dionysiac cult might be compared to tribal initiations. It seems that initiation into the Dionysiac Mysteries was accompanied by initiation into sexual life.
