Aesop's Fables.

Aesop's Fables are a collection of fables credited to Aesop, a slave and story-teller believed to have lived in ancient Greece between 620 and 560 BCE.

The fables remain a popular choice for moral education of children today.

Many of the stories, such as The Fox and the Grapes (from which the idiom "sour grapes" derives), The Tortoise and the Hare, The North Wind and the Sun, The Boy Who Cried Wolf and The Ant and the Grasshopper are well-known throughout the world.
