Lol. More like Dune lifts wholesale from Sabres of Paradise, translating the stories about Imam Shamyl into space, only adding some bits of LSD inspired trippiness. If anything, Herbert toned down the historical accounts. On the other hand, Lesley Blanch went for the dramatic over the historical in Sabres. The story about the Sultan that drowned his son's mistress, for example, was from a Greek movie version.
