Poul Anderson And Frank Herbert

In Poul Anderson's Technic History:

the planet Aeneas resembles Frank Herbert's Dune that it is a dry, humanly colonized planet that is a potential flashpoint for an interstellar jihad;

the planets Satan and Mirkheim resemble Dune in that they are single sources of unprecedented wealth - except that Dune is more so (see the combox here).

Herbert's Dune series focuses on a single fictional planet whereas the Technic History presents:
