 It was the first post-Howard attempt at serious world-building of a fantasy setting in the Howard vein, prefiguring the numerous sword & sorcery settings of the 1960s and 1970s.Just as de Camp attempted to do for the Barsoom novels of Edgar Rice Burroughs with his "Krishna" stories, the Pusadian stories represent both a tribute to Howard's prehistoric "Hyborian Age" and an attempt to "get it right", reconstructing his model's concept logically, without what he regarded as Howard's anthropological and geological absurdities.Unlike Howard, de Camp brought a thorough knowledge of ancient history and geography to his project, along with a wealth of research on prior literary treatments of speculative prehistoric civilizations, as reflected in his definitive study "Lost Continents" (1954).
