And speaking of embarrassing, some amusing posts way back there were discussing the possibility of filming the trilogy, although the characters' nakedness in Perelandra would present an artistic difficulty. That got me to thinking about nakedness as a theme that runs not just through Perelandra, but through OotSP and THS, as well.
In OotSP, Ransom is, at first, naked in his naivety and vulnerability, kidnapped and escaped on a foreign planet where he fears death from sacrifice if he is caught, and death from starvation or exposure if he is not caught. He has no hope of returning home, and no hope of finding the comfort of friends if he manages to keep himself alive. He is effectually stripped of all solace and hope, made utterly alone. Of course, thank Maledil that that nakedness doesn't last longer than one day and night! Ransom neither starves nor remains alone and friendless. And his fears of being made a human sacrifice are put to rest, at least until the next book!
Then in Perelandra, Ransom is physically naked, as Adam was and is. But this time there is no danger of exposure or starvation; the world supports life almost effortlessly, and nakedness is both necessary, because of the warmth, and beautiful, because the body relaxes in the state of existence it was originally built for, basking in the warmth of God and His creation.
Then in THS, it is the world that is stripped naked; human motives and temptations and faults, the traps and snares of the devil, the goodness and grace and mercy of God, are all exposed in their true shapes and colors. The polarity of good and evil is no longer a convention of story and myth, but a clarifying image of the way things really are. Every thought and every action is either for God or against him. Both good actions and bad actions have their momentum and can snowball without warning. Both Jane and Mark come to realize that their own actions can determine the fate of others. Both Jane and Mark are made naked as part of a healing and reconciliating process; they are taught that their past views and attitudes were mistaken. They both come to God along opposite but like paths; Mark by discovering what true evil means, and Jane by witnessing what the truly good can do about it.
