The Eyes of the Overworld

The Eyes of the Overworld is a picaresque fantasy fix-up novel by American writer Jack Vance, published by Ace in 1966, the second book in the Dying Earth series that Vance inaugurated in 1950. Retitled Cugel the Clever in its Vance Integral Edition (2005), the story takes place in Vance's Dying Earth setting, where the Sun is dying and magic and technology coexist. It features the self-proclaimed Cugel the Clever in linked episodic stories. Cugel is an anti-hero character; while he is typically a crafty scoundrel who seeks to turn a profit from a situation, he retains some good values at times. In the novel, Cugel is caught stealing from a wizard, who forces Cugel to travel to a faraway realm to find a rare magical jewel.

The components of the fix-up were five short works published in The Magazine of Fantasy & Science Fiction from December 1965 to July 1966, and one original to the book.

The 1934 film The Spectacle Maker, based on the 1913 Frank Harris story "The Magic Glasses", also features magic spectacles which show the wearer beautiful illusions instead of reality, as the eponymous "Eyes of the Overworld" do.
