Dying Earth is a fantasy series by the American author Jack Vance, comprising four books originally published 1950 to 1984. Some have been called picaresque. They vary from short story collection to fix-up (novel created from older short stories) perhaps all the way to novel.
The first book in the series, The Dying Earth, was ranked number 16 of 33 "All Time Best Fantasy Novels" by Locus in 1987, based on a poll of subscribers, although it was marketed as a collection and the ISFDB calls it a "loosely connected series of stories".
