Ooh yes DD - very interesting - if my memory serves correctly - this is a very old carving in a French church or cathedral, and it depicts the suicidal hanging of naked Judas Iscariot - with a little help to send him on his way from a couple of demons.
Somewhere in my archive I have a colour version. When I get time I will have a rummage and see if I can find it.
Found it.
Now when I first saw this carving, I wondered if the stone mason was being a bit naughty and sneakily carved Judas holding onto his dick with his right hand - or - was it just a badly carved finger???? Have a look and see what you think for yourself
Those demons surely knew about hung men spraying their death load upon dying (and mandrake growing where the semen spilled onto the ground), and are happily anticipating that moment. I'd help myself a little too before it was too late to experience this last moment of bliss.
