"The Frost King" is a short story about King Jack Frost written by Helen Keller, then 11. Keller's teacher, Anne Sullivan, had mentioned that the autumn leaves were "painted ruby, emerald, gold, crimson, and brown," and Keller, by her own account, imagined fairies doing the work. Keller wrote a story about how a cask of jewels, being transported by fairy servants, had melted in the sun and covered the leaves.
