Hand in your coats, turn right and you'll come to the Yeats Rooms. The two paintings hang side by side on your left. One, The Liffey Swim, is probably one of the most famous modern Irish works.
El Greco's St Francis Receiving The Stigmata is the first of a series of short reflections on pieces in the National Gallery of Ireland on Merrion Square. I do have a rather handsome photograph of the painting, which I would like to post alongside the essay, but unfortunately the copyright provisions of the National Gallery seek to prevent me from doing so.
