Henri Lhote (1903-1991) was a French explorer and ethnologist who is best known for his discovery of remarkable cave paintings in the Sahara at Tassili-n-ajjer^[442]. One of these was dubbed the ‘Great Martian God’ and exploited by Erich von Däniken in the promotion of his ‘ancient astronauts’ ideas. Jürgen Spanuth notes^{[017 p.22]} that in 1950 Lhote organised an expedition to Tanzerouft in the Sahara with the hope of finding Atlantis although there was no subsequent claim by Lhote of such a discovery.
