Aesop, according to various sources, was born in Phrygia, Lydia, Thrace, or Sardis, and lived from about 620 to 560 B.C. Little is known about his life, but Aristotle mentioned his acting as a public defender, and Plutarch numbered him as one of the "Seven Wise Men." It is generally believed he was a slave, freed by his master because of his wit and wisdom. As Aesop became famous for his fables, which used animals as a code to tell the truth about political injustice, he incurred the wrath of the rulers, either in Athens or Delphi, and was executed. In about 300 B.C., Demetrius Phalereus of Athens made the first known collection of Aesop's fables, which then spread far beyond the Greek world.
