Also it's very dark. Some of the things I'd like to have photographed were so deep in shadow I didn't even try. This particular capital was in the twilight zone. I doubted it would come out but I gave it a shot- and processed the result. The image is grainy- but then so is original stone.
A person sits on another person's head holding a fish in one hand and something indeterminate in the other. Is this the boy who supplied Jesus with the loaves and fishes with which he fed the 5,000? Seems unlikely: for one thing he apears to have a beard and moustache and for another the indeterminate object looks more like a bowl than a loaf. But I don't have any other suggestions. I've not seen anything like it before.
