I've never needed to use a seal for Arzel, but I'm going to try something a little different soon. So I decided, based on previous experience with Hebrew angelic names having a connection in and of themselves, to place Arzel's name within a circle of the Hebrew for psalm 80:10...were he's linked to the mountains and (specifically) the ceders (hence his name) being shadowed by the branches of the transplanted vine etc
Thanks to raum for posting the reference to the Psalm in another thread.
So play around with this if you like and see what transpires It might even be worthwhile trying a proto-hebrew script given the age of the psalm.
