Elwin Ransom
Elwin Ransom may be based on C. S. Lewis' friend J. R. R. Tolkien ("Elwin" means "Elf friend" in Anglo-Saxon), though he seems to have autobiographical elements. In "That Hideous Strength" Ransom, with his royal charisma and matter-of-fact breezy acceptance of the supernatural, appears less like Tolkien than like Charles Williams (or some of the heroes in Williams' books).
Proverb
Probably the most famous user of proverbs in novels is J. R. R. Tolkien in his "The Hobbit" and "The Lord of the Rings" series. Herman Melville is noted for creating proverbs in Moby Dick and in his poetry. Also, C. S. Lewis created a dozen proverbs in "The Horse and His Boy", and Mercedes Lackey created dozens for her invented Shin'a'in and Tale'edras cultures; Lackey's proverbs are notable in that they are reminiscent to those of Ancient Asia - e.g. "Just because you feel certain an enemy is lurking behind every bush, it doesn't follow that you are wrong" is like to "Before telling secrets on the road, look in the bushes." These authors are notable for not only using proverbs as integral to the development of the characters and the story line, but also for creating proverbs.
