C. S. Lewis
Lewis and fellow novelist J. R. R. Tolkien were close friends. They both served on the English faculty at Oxford University, and were active in the informal Oxford literary group known as the Inklings. According to Lewis's memoir "Surprised by Joy", he was baptised in the Church of Ireland, but fell away from his faith during adolescence. Lewis returned to Anglicanism at the age of 32, owing to the influence of Tolkien and other friends, and he became an "ordinary layman of the Church of England". Lewis's faith profoundly affected his work, and his wartime radio broadcasts on the subject of Christianity brought him wide acclaim.
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.
