Has anyone read any really good books on Dionysus? I'm looking for good historical research about his nature and how he was worshipped/contacted by the ancients. I am not looking for some neopagan rehash garbage about what a wonderful drunk version of Jesus he was/is.
I know that there were human sacrifices made to him etc. I want to understand his festivals, his lore etc. as researched by serious scholarly types.
If anyone can point me to anything I'd appreciate it. Even if it to someone else that may be able to help, it would be a start.
