20th century works inspired by the Henu Barque ?

a) On December 31st, 2018, I realised that  "El sueño de Sancho" (The dream of Sancho) (1978) by Jorge Camacho appeared to reference "Jessica" from The Illustrated Dune, (1978) by John Schoenherr

 b) "Jessica" from The Illustrated Dune, (1978) by John Schoenherr

b) The plant on the upper left with a horned look to it becomes a similarly placed horned form in Camacho's painting, but he created an animla like head with something growing from the top as if it were on a stalk.

 c) Jessica's head band perhaps becomes the stalk.

d) The flower on the upper right becomes Sancho Panchez holding a stick

e) The strange flower with flesh tentacles across the lower part of the drawing becomes the face with a arm like nose, while the far right tentacle becomes the red brown animal tail like form on the right.

   

f) Sleeve from Jessica's garment and the space between the two wires and the handle
