Good stuff, have you any links to this or is this all from memory?
Yes I remember that one, something about seeking the Heart of Ahriman or something? Some squire wears Conan's armour (as Conan has been paralysed by that sorcereor) and is killed.
I think in the UK we think of this genre as Heroic Fantasy where the male characters are larger than life and all women are knock-outs. On the other hand as someone has already said Kane is an anti-hero and is more like Sword & Sorcery and I wouldn't say he was Heroic Fantasy.
This was all from memory, but I could annotate much of it. Here are some examples, sort of, as I still dont' have the exact sources handy. But as you said Conan was captured after the battle where his double was killed, so to everyone else he was dead. The guy that brought the cliffs down on the fake Conan, and destroyed most of the army, the "Flower of Aquilonian Chivalry', was Xaltotun the resurrected evil wizard of Acheron. He was a symbol of the Anti-Christ. So Conan was imprisoned in the bad guys dungeon for precisely three days, just like Jesus was before the resurrection. The first person to see Jesus reborn was Mary Magdellan. For Conan the first person he sees is Zenobia who helps him escape and he eventually marries, so she is like Mary. When he gets out and finally high tails it back to Aquilonia, the first person he sees there is one of his loyal 'publicans' which is essentially a 'King's Man' in this definition. The publican, when he sees Conan, asks are you a ghost? Conan replies "No man I am flesh and bone. Give me a paste (a pattie of breaded fish or meat) and some wine'. In the Bible when Jesus first appears to the other aposltes they ask him if he is a ghost to which he replies, 'No, I am flesh and blood. Give me some fish and wine and I will show you". There are more examples, I did a paper on it in college, which I don't have, and I had lots of footnotes to almost word for word quotes from the Bible to the Conan story. I grew up in a town about 30 miles from Howard's and I assure you he knew the Bilbe well.
So the point (and I do have one) of that is that this book has a battle between the 'good' armies of the west, like Aquilonia and its allies against the 'evil' armies of the east, and their leaders who resurrected Xaltotun, who was going to bring back Acheron and enslave all of the known world. (Don't get me started on the East vs West thing). So it was an epic struggle of good versus evil and nations for the fate of the world, which is, apparently the definition of 'High Fantasy'. Which is apparently almost synonomous with 'Heroic Fantasy'. Where as sword and sorcery is something more like D&D type small scale 'scenarios' of danger, drama, and, well, swords and sorcery. Michael Moorcock is credited with creating the anti hero character, Elric. Moorcock is also the person that coined the phrase 'Sword and Sorcery' and the anti hero is something more associated with S&S than High Fantasy, or Tolkienesque Fantasy. Moorcock, Fritz Lieber, and many others credit Howard as the father of Sword and Sorcery because most of Howard's printed work on him was just him wondering around and having bizarre adventures. To confuse matters more Steven R. Donaldson's character 'Berek Half'-Hand' was an anti-hero type figure, who actually is the protaginist in a 'High Fantasy' type story. Howard's 'Hour of the Dragon' was never published as one piece in his lifetime. But my point is that in 1935 Howard's "Hour of the Dragon" could be considered the first modern "High Fantasy" novel. Further, I think Lovecraft probably introduced Howard's type work to Tolkien. So Howard is really the progenitor of High Fantasy and Sword and Sorcery.
If you want some resource material of where I am getting this classification of 'Sword and Sorcery' vs 'High Fantasy" just google 'Sword and Sorcery' and there is a wiki article on it and some other stuff. There is also a recent book called 'Swords and Dark Magic' which has a forward on the subject.
Given some time and some motivation I could reference exact lines and versus, but no one has the time and, therefore, I don't have the motivation.
