I've been getting a lot of book-related posts from Catalonia which fits in with that.

I recently listened to a CD "Igry Bagou" (Games of the Gods) from 2005 by the Belarus ethnographical vocal group Guda. They have some songs related to the Indo-European god Yaryla, who was Christianized as Yurya (St George). He is associated with thunder and the spring, in opposition to the dragon, who is a principle of darkness and the underworld. Seems to be an emanation of the supreme god Perun/Piarun. Which helps explain why he is so significant in some European traditions despite being such a dead loss as a historically real Christian saint (Gibbon had the goods on him).
