Caresco surhomme; ou le Voyage en Eucrasie. 1904
1 of 3 coloured illustrations for this superb old French scifi. "Dr. Caresco was the one of the first modern mad scientists in litterature.
Caresco rules the island of Eucrasia, an island whose inhabitants are changed by surgery to better do their jobs; the captain of the plane which brings "guests" to Eucrasia is a limbless trunk with telescopic vision--the better to help him fly, you see. The island itself is in the shape of a human body. The natives of Eucrasia are addicted to various sensual pleasures, but submit (for the most part) to Dr. Caresco's rule, for fear that he will castrate them or worse.
Caresco is brilliant as well as mad. Making use of Omnium, a mysterious and unexplained power source, Caresco creates scientific prodigies: a machine capable of stripping the years from a person and reversing the aging process, a very fast underground train system, food pills, Omnium-powered diving suits, and so on. But Caresco is mad as well as brilliant, given to things like collecting the spleens of all those he operates on, and eventually he dies, Eucrasia being blown up by a volcano."
