I watched the movie "The Secret of Kells" last month, and I LOVED it. For my BFA, I am going to do Irish or Welsh mythology and tales illustrated in the style of The Book of Kells, and other illuminated celtic manuscripts (Mulling, Dimma, Durrow, etc). I started looking at scans of the pages of these books and I was blown away. I've been becoming increasingly obsessed with them the past week, and have started practicing a lot of the designs in my sketchbook.
Look how beautiful these are:
The Chi Rho page in the Book of Kells
BOOK OF DURROW. Top: Carpet Page, Bottom: Gospel of Mark
Another from the Book of Durrow
Some more from The Book of Kells
Here's a cool article I just found: http://www.news.cornell.edu/stories/Sept09/KellsAngels.html
