One of the things I found fascinating about him was his research of ancient books to find how to divide a page in pleasing proportions, He studied the page layout of ancient monks and Gutenberg’s 9×9 layout and eventually demonstrated the geometry and published about his findings.
I then did an experiment to see what the “grid” would be for 8.5 x 11 inch pages. The dimensions are shown below.
If you are attempting to create a historical theme with a “feeling” of being “old, ancient, or spiritual,” this is a good format. It’s great for storybooks and fairy tales. It may be appropriate for a thematic brochure. The idea is the page layout alone creates a subconscious “reminder” of days gone by. In reality, it’s not “perfect” for every application. But trying it out on your page dimensions can give you new perspective.
