In The Aesop Romance, Aesop is a slave of Phrygian origin on the island of Samos, and extremely ugly. At first he lacks the power of speech, but after showing kindness to a priestess of Isis, is granted by the goddess not only speech but a gift for clever storytelling, which he uses alternately to assist and confound his master, Xanthus, embarrassing the philosopher in front of his students and even sleeping with his wife. After interpreting a portent for the people of Samos, Aesop is given his freedom and acts as an emissary between the Samians and King Croesus. Later he travels to the courts of Lycurgus of Babylon and Nectanabo of Egypt – both imaginary rulers – in a section that appears to borrow heavily from the romance of Ahiqar. The story ends with Aesop’s journey to Delphi, where he angers the citizens by telling insulting fables, is sentenced to death and, after cursing the people of Delphi, is forced to jump to his death.
