I don't think I've ever seen anyone look so different from picture to picture! Even basic facial features look different.
In the black and white one, he looks a lot like Edgar Allen Poe, but of course is not, since he looks like someone else entirely in all the other pictures.
In the first pic, he looks sad, serious, concerned and caring, the type who has the courage of his convictions.
In the second pic he seems gruff and a bit grumpy, maybe due to how long he had to sit still to pose.
In the second pic, I see an inhumanly tall being behind his left shoulder, that looks like maybe an angel or guide, and on his right side, something that looks like the stereotypical head of a devil, turned to look at him with great hatred. So, I'm going to take a flying leap here and say that I think he may have written about things having to do with theology, good and evil and the nature thereof, possibly in what was considered a heretical way at that time.
I need my morning coffee.....more later.
