For Victor in 2001, I made an ornamental letter C based on a Celtic design. C is the first letter of Carsrud, Victor's last name, and also the first letter of Campbell, the Scottish clan that he descends from. When I was in Ireland the previous summer, I saw a lot of Celtic designs firsthand, and I bought a few books about Celtic artwork. The best is George Bain's Celtic Art: The Methods of Construction. Bain's book is absolutely full of ideas and instructions on how to create knots, spirals, keys, animals, and more. The basis of this design is a lowercase letter e, which is copied from the Book of Kells (we got to see the Book of Kells in Dublin!).
