When I tackled Bartleby as an illustration, I knew I didn't want to do an 1800s thing. I wanted to keep visually to the milieu that we associate with classic fantasy RPGs, so I went more "monk-ish." And since I've been digging through a lot of old books lately (like the books that led to the recent Arthur Rackham clip art post), I had a Walter Crane thing in mind. I have a great respect for Crane as book illustrator and writer (more specifically than just an artist). In his book Of the decorative illustration of books old and new, Crane states:
"...I have endeavoured to draw the line between the purely graphic aim, on the one hand, and the ornamental aim on the other—between what I should term the art of pictorial statement and the art of decorative treatment; though there are many cases in which they are combined, as, indead, in all the most complete book-pictures, they should be."
He's really talking about illustrations that have a quality of ornament, rather than being simply renderings of subjects. And, IMHO, nobody has (or ever will) do that better than Walter Crane. My Bartleby illustration (below top) is my my homage to him; and the typeface choice (Troy) is a nod to its creator William Morris (one of the people who inspired Tolkien, and a frequent printer-collaborator with Crane).
The Ariphas illustration (below middle) is a little on the goofier side. I may end up redoing this so it's a little less "cartoony", but I also trust the instincts of my initial thoughts and sketches (like the ones that led me here).
Gnunnug (the illustration below bottom) is actually a listing from the original Petty Gods book that didn't have an illustration. The listing doesn't explicitly say Gnunnug has seven fingers and toes on each limb, but it seemed natural that he wood (being the petty god of the number seven).
