Quite a few differences, actually. And I think they do matter.
The 2nd version has a crown, a scepter (broken), an apple (bitten), the chains, horns. Etc.
Artistically, I like it. I’m not sure I would want it in a church building, but the artist does a very good job (in my opinion) of making the point that earthly beauty doesn’t count for much in terms of our eternal state. He’s good looking, but he’s miserable. And the more one looks, the less good-looking he gets. Take the face for example. From a distance, he looks attractive. Get closer and look at the details, and all that beauty becomes an illusion.
From a distance, his face looks handsome. Get closer and he looks ugly. He has a tear coming from his left eye. His skin bulges as if there were worms crawling underneath his skin. His hair looks like a $700 haircut from a distance, but get closer and it resembles a bed of writhing snakes. His horns are there, but only if you look closely. In other words, the beauty is deceptive. I certainly see the genius of the artist in conveying that idea: Satan looks attractive from a distance, but it’s all an illusion. The closer one gets to Satan, the more the evil appears. Seriously, artistic genius.
I also like it because it immediately reminds me of a very popular theme in Christian art: Christ after the scourging, or ecce homo.
I’ve seen better, but have a hard time finding a good example to post.
Here’s the point:
The statue of the devil is the opposite of that of Christ.
Christ wears His crown of thorns and holds His scepter. From a distance, it looks like defeat, but in reality, get closer and the defeat becomes victory. His hands are bound, but crossed over His chest in a classic gesture of prayer. Contrast that with the chain that permanently binds Satan to the rock.
Satan’s hands are free of any binding, but chaotic, confused, angry (note how the knuckles stand-out showing how tightly his left hand grips the broken scepter.
The broken scepter itself is in his left hand (not the right hand, the hand of justice). Justice is reversed!
