My contention (once I got past my teenage years) was that the Wheel of Pain, in the original Conan the Barbarian movie, was supposed to be alegorical...a symbol of Conan's difficult upbringing as a slave. Most people, however, seem to view it as literal...that he had to push this wheel around for ~10 years...presumably as a grain mill.
Is there some kind of source, either in movie or outside of the movie, that could explain this more definitively? Answers claiming "it's totally such-and-such" without supporting evidence are okay (though more than one answer of the same kind should be avoided in lieu of voting up a pre-existing one) and no answer without some kind of support will be marked as accepted.
