That's the intriguing title of an article at Flashbak (with a tip o' the hat to Ace of Spades for the link). Here's an excerpt.
What image could be more ubiquitous in science fiction and fantasy art than the mighty well-armed He-Man with damsel at his feet?
I call it the “Conan Pose” after the most well-known and biggest repeat offender of the trope.
The device is as simple as this: (1) the man is a rugged warrior who is generally armed ...
... and (2) the woman is positioned beneath him and is generally defenseless.
Like the Women Running from Houses theme, which you see again and again in gothic romance, the “Conan Pose” is repeated ad nauseum in the science fiction and fantasy world and beyond.
There are many more examples at the link. Fun from a literary-historical perspective, and even more fun because they make feminazi's and Social Justice Warriors froth at the mouth! I have to agree that in terms of modern culture, they're irredeemably sexist and male-chauvinist; but that sort of thing will probably always be with us. I'm just waiting for the feminist version, with an Amazonian female dominating male hangers-on!
