Prometheus Unbound: What The Movie Was Actually About
This blogpost contains many and frequent spoilers for Prometheus, so if you're planning on seeing it, I recommend you don't spoil yourself.
Prometheus contains such a huge amount of mythic resonance that it effectively obscures a more conventional plot. I'd like to draw your attention to the use of motifs and callbacks in the film that not only enrich it, but offer possible hints as to what was going on in otherwise confusing scenes.
Let's begin with the eponymous titan himself, Prometheus. He was a wise and benevolent entity who created mankind in the first place, forming the first humans from clay. The Gods were more or less okay with that, until Prometheus gave them fire. This was a big no-no, as fire was supposed to be the exclusive property of the Gods. As punishment, Prometheus was chained to a rock and condemned to have his liver ripped out and eaten every day by an eagle. (His liver magically grew back, in case you were wondering.)
Fix that image in your mind, please: the giver of life, with his abdomen torn open.
We'll be coming back to it many times in the course of this article.
