Yesterday's post by John Cutrone about St. Barthlomew, the patron saint of bookbinders and book artists, on his Book of Days blog led to a conversation on the Book Arts List about other patron saints of bookbinding. You can read about them in the following posts. The picture above is from The Man Who Loved Books by Jean Fritz, illustrated by Trina Schart Hyman.

A post about the children's book about Saint Columba, The Man Who Loved Books, on The Art of Children's Picture Books blog. This is a favorite of mine.
