FRANK R. PAUL'S JOVIANS / JUPITERIANS

In 1940, science-fiction art pionneer Frank R. Paul did pieces showing what life could be on other planets. In his own words:

Jupiter's inhabitants need to be massive, or tremendous strenght to cope with the enormous gravity ot this giant world. They would probably be forced to a clumsy mode of locomotion, since long legs would be impossible. An earhtman would need a tractor to get about.

Paul depicts massive sextupeds able to move on 4 or 6 legs, usually using the first, longer ones for prehension. He presents us a civilisation that has developed industrialisation and advanced urbanism but that does not seem to have started its space age.
