Some books and stories are built around a proverb. Some of Tolkien's books have been analyzed as having "governing proverbs" where "the acton of a book turns on or fulfills a proverbial saying." Some stories have been written with a proverb overtly as an opening, such as "A stitch in time saves nine" at the beginning of "Kitty's Class Day", one of Louisa May Alcott's "Proverb Stories". Other times, a proverb appears at the end of a story, summing up a moral to the story, frequently found in Aesop's Fables, such as "Heaven helps those who help themselves" from "Hercules and the Wagoner". In a novel by the Ivorian novelist Ahmadou Kourouma, "proverbs are used to conclude each chapter".
