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. Plot summary Cugel is easily persuaded by the merchant Fianosther to attempt the burglary of the manse of Iucounu the Laughing Magician, which is filled with precious magical items. Caught by Iucouno's trap, Cugel agrees that in exchange for his freedom he will undertake the recovery of a small hemisphere of violet glass, a magic "Eye of the Overworld", to match one already in the wizard's possession. A small sentient alien entity of barbs and hooks, named Firx, is attached to Cugel's liver to encourage his "unremitting loyalty, zeal and singleness of purpose". Firx's only form of communication with its host is to cause pain to his liver if Firx senses that Cugel is lapsing in his mission and his return home. Iucounu then uses a spell to transport Cugel via flying demon to the isolated Land of Cutz, which is very far away. There, Cugel finds two bizarre villages, one occupied by wearers of the magic violet lenses, the other by peasants who work on behalf of the lens-wearers, in hopes of being promoted to their ranks. The lenses cause their wearers to see, not their squalid surroundings, but the Overworld, a vastly superior version of reality where a hut is a palace, gruel is
