Robert E. Howard was, I am coming to understand, a master of his craft.
What is the difference between a real savage and a noble savage? Let us look into the iron shadows of the moonlight for an answer.
This story is well suited to the question, for it just so happens to have a lovely, half-clad and large-eyed brunette in distress; a highly civilized oriental aristocrat bent on her dishonor; a rough and semi-civilized pirate chief who hates Conan with hot passion (and wants him hanged on a hook); eldritch monuments from a forgotten civilization, haunted perhaps with the ghosts of an accursed peoples; and an apelike monstrosity equally likely to originate from the darkness of prehistory as the darkness of the netherworld.
In other words, we have one antagonist from each season of the rise and fall of cultures from primitive to civilized to decadent to dark ages and back to prehistory again.
As they say, Read the Whole Thing. And I have further contrasts of Conan with more modern fiction here, if you’re into that sort of thing.
