Yes, I know, an odd, random thought that came to me and I just started drawing. But it’s true, hair on the body is impure in religious art, even the newer comics. Try doing a Google search for Adam and Eve and take a look at all of the classical artwork–no hair! I believe hair may represent our earthly sexual desires–it’s more animal-like. It reminds you of sex (think Sean Connery without a shirt on). Interestingly enough, modern porn likes to shave off hair down below, not for the sake of purity but so you can see everything clearly. Thus they have thwarted the artists of Adam.
I’m sure there’s more to it than that, but find me a hairy Adam…must be one somewhere?
