That is a painting not a photograph.
It is nice that the Catholic Church of that day was a little less barbaric than the secular world, but it still makes one wonder how anyone claiming to be Christian could be that cruel. The bible makes it clear what they should have done with the blasphemer: kicked him out of the church and treated him with the same disdain as a pagan.
Oh, but if you do that, you don't get to confiscate his property and lands "for the Church", as was done then.
