This is a really interesting question as compared to other Greek gods the worship of Dionysos has been difficult to stamp out. I hope that my readers have a basic grasp of history, in that in Europe for a 2,000 year period Monotheism rose up and sort to quell (putting it lightly) any form of worship other than that dedicated to Christ.
Even upon the threat of death Dionysos continued to receive honour well into Christen times. The performance of transvestism during wine making rituals was not formally banned until 691AD by the Council of the Church in Constantinople. Although the theatres were formally closed by Emperor Justinian in the 6th century, performance continued to be an aspect of medieval life, entertaining nobles and common people alike. If we look past the Dark Ages we given an insight into the no-so-long dead cult of Dionysos including a revive in the Renaissance by Lorenzo the Great and later activities like The Hellfire Club in Britain and Ireland in the 18th century. During the 1960’s Dionysos saw a revival through stage performance and music, and also the Rave movement of the late 1980’s and early 90’s, including the use of the aptly named drug Ecstasy.
Point being, comparable to other Greek / Roman deities Dionysos in some form or another has lasted through multiple epochs of time. His cult has changed depending on circumstances but the essence of it has always remained the same.
Dionysians, who call themselves that as an actually as devotees, now face differing dilemmas, including the taboo topics of animal sacrifice, prohibitions against drugs and alcohol, social issues regarding supposed excess etc. These sigmas exist within the ‘pagan community’ itself with some so-called pagan writers (Sam Webster) advocating the abandon of the god.
It is now, as custodians of Dionysos, that we strive to educate and produce art demonstrating the marvellous power and inspiration of the great god Dionysos.
