Christ Enthroned (Book of Kells) - multiple monastic scribes(c.800)
Iron Gall ink, various imported pigments on vellum.
They really captured the spirit of this style in "Secret of Kells." Just looking at this made Aislinn's haunting spell-song for Pangur Ban start in my head:
You can go where I cannot Pangur Ban, oh Pangur Ban
🥰
I really need to find this and watch it ;)
