Where the imagery of Christmas is concerned, I am an old fogey. I like to be surrounded by cards bearing paintings of the Holy Family by Old Masters; or, failing that, pictures of robins; or even, if it comes to it, snowy village scenes with a horse-drawn carriage pulled up outside the inn, the church tower looming through the fog, urchins gambolling back and forth, and so on.

And yet I also find myself drawn to the Nativity scenes created in stained glass by the Irish artist Harry Clarke, which often stray quite a long way from familiar styles and formulas.
