While not religious or a Christian except by upbringing (CoE), I've always been fascinated by religious art. Especially the crucifixion. It's the absolute central tenant of Christian doctrine so has been covered endlessly, ruthlessly, one may argue.
This one I've actually seen. And it's an incredible piece of art for its size. Especially as some of the crucifixion pieces are gigantic. Life-like, almost.
Very interesting piece, as always.
