HR Giger: Erotomechanics VIII (work-423) (1979) by HR Giger references "L'Origine du monde" (1866) by Gustave Courbet via "Landing Ground at Nazca" (1976) by Chris Foss ?

 Leading from

 ‘Landing Ground at Nazca’ (for the book "Visitors from Outer Space") (1976) by Chris Foss 

and

Erotomechanics VIII (work 423) (1979) by HR Giger  

and

Gustave Courbet's L'Origine Du Monde (1866) 

a) The three one above the other above the other with Courbet's "L'Origine Du Monde" (1866) on top.

 

b) My idea would be that Giger probably saw how the space ship was obviously the futuristic version of the pubis for "L'Origine du monde"

c) So the crisscrossing Nazca lines from Foss' piece would become the Eiffel Tower like lattice of garters and suspenders etc, but it's not as if there's a direct reference to any particular Nazca line from Foss' piece in Giger's
