Unfortunately, no I don't know any good online sources. I used to blog on the topic, but that was a few years ago and I don't trust my memory or ability to academically site stuff as much as I used to.
If you ever have the chance to check out Kerenyi's book on Dionysos, though, it's AMAZING. Beautifully written, and split between the more Minoan Zagreus, and Greek Dionysus. It's probably my favorite book, ever.
I'd like to start writing about this topic again some day, but like you need to clear some stuff up first. :)
sweet, ill look for the book. The research never ends :P
I just googled Zagreus, and its very interesting. Gives more meaning to Dionysus' imortality and twice born quality, though I wonder if he could be considered thrice born.
I could definitely see that. He can be a difficult figure to keep up with, since he seems to have jumped around a lot geographically. I vaguely remember reading something about his ties to Hinduism, even!
yeah he is sort of like wine in that way haha, it grows everywhere differently. It is basically impossible to actually understand the diversity of wine, or of Dionysus.
