 Thus the "happiness" of Croesus is presented as a moralistic "exemplum" of the fickleness of Tyche, a theme that gathered strength from the fourth century, revealing its late date.The story was later retold and elaborated by Ausonius in "The Masque of the Seven Sages", in the "Suda" (entry "Μᾶλλον ὁ Φρύξ," which adds Aesop and the Seven Sages of Greece), and by Tolstoy in his short story "Croesus and Fate".According to Herodotus, Croesus desired to discover which of the well known oracles of his time gave trustworthy omens.
