Aesop (620-560 BC) has been known in history and in legend since the sixth century BC, or earlier, as a gifted Greek storyteller and the author of the world's best-known collection of fables. A Phrygian slave, there is speculation that he was freed as a result of his wit. Though little is known about his life, his remarkable wisdom regarding human nature, conveyed through his fables, has brought him great renown.
