Dionysian Mysteries

"We have no texts explaining the rites and ceremonial of the Dionysiac mysteries in the Greco-Etrusco-Roman world, although there are allusions which can often be clarified with the aid of Indian texts... By studying Shivaite rites [from India], the only ones which have continued down to our own times, the real practices of the Dionysiac rites and “mysteries” may be reconstructed."
