We slipped into the Chapter House of Canterbury Cathedral in order to see the exhibition of Romanesque stained glass from the South Window.   Some of the figures date from before the fire of 1174, so are amongst the earliest stained glass in the country, designed by an artist known only as the Master of Methuselah.   They are what remains of 86 figures originally placed in the clerestory of the choir, so invisible to the human eye.   This did not prevent an extraordinary display of vigour and humane realism:-
