.....Here they're priest/type workers are preparing this corpse similar as the vatican workers prepare their corpses, to be put into position and displayed as seen below this photo...
They remove body parts as well....the soles of the feet, palms of the hands and tongue are sliced off and presented to the surviving spouse... and then what's left of the body is smoke cured over a fire pit, but not before sprucing them up before .. robing/coating them in clay and ochre............ The most-respected warriors are placed on 'special' lookout points on the cliffs, watching out for invaders....rather like catholics believe the spirits of the departed watch over them....
This man is honoring his dead by visiting, though he doesn't appear to have his head bowed, nor hands folded , nor on bended knee before this corpse.
They could be Catholic!
Gives a quite different twist to the phrase: Man Cave!
