The crowned one
firemaiden said:Is there any support for the graal connection going back further than the RWS?
Yes, it was a common theme based on Robert de Boron's stories.
The courts were often named after popular medieval romances and the nine worthies. For example the cup of knights was labeled "Lancelot" in some decks.
I am following this thread with interest but have northing good to add at this point.
