From a really penetrating book review by David Ulin in, yes, the Los Angeles Times, a fascinating historical idea/fact:
"No one remembers," [author Lawrence Osbourne] tells us, "that Dionysianism was the most popular religion of the late [Roman] empire before the arrival of Christianity. It was Christianity's principal rival...We have even forgotten that Dionysianism was a religion at all."
Book is The Wet and the Dry, by Lawrence Osbourne. Makes one wonder if this "religion" has simply morphed into the wine and spirits culture of today.
