Aesop (620-564 BCE) was a storyteller that was believed to have lived in Ancient Greece. He is celebrated for a number of fables now collectively known as Aesop's Fables. In the few scattered sources about his life, Aesop was described as a slave who by his cleverness acquires freedom and becomes an adviser to kings and city-states. Although Aesop's existence remains unclear, numerous tales credited to him were gathered across the centuries and in many languages in a storytelling tradition that continues to this day.
