“No act of kindness, no matter how small, is ever wasted.”
The Lion and the Mouse.
Variant: No act of kindness, no matter how small, is ever wasted.
Aesop was a Greek fabulist and storyteller credited with a number of fables now collectively known as Aesop's Fables. Although his existence remains unclear and no writings by him survive, numerous tales credited to him were gathered across the centuries and in many languages in a storytelling tradition that continues to this day. Many of the tales are characterized by animals and inanimate objects that speak, solve problems, and generally have human characteristics.
Scattered details of Aesop's life can be found in ancient sources, including Aristotle, Herodotus, and Plutarch. An ancient literary work called The Aesop Romance tells an episodic, probably highly fictional version of his life, including the traditional description of him as a strikingly ugly slave who by his cleverness acquires freedom and becomes an adviser to kings and city-states. Older spellings of his name have included Esop and Isope. Depictions of Aesop in popular culture over the last 2500 years have included many works of art and his appearance as a character in numerous books, films, plays, and television programs.
