The terrible parallels hit you like a bucket of cold water in the face -- at least if you have been immersed for a while in Scotland's Highland Clearances. Check out the image to the right. Looks like it could be from a Scottish Clearance in Sutherland or Glengarry, or perhaps Lewis, Uist or Barra. In fact, it's from County Clare in Ireland -- Mathia Magrath's house "after destruction by the Battering Ram." I know this because today we checked out the Irish Famine Exhibition at St. Stephen's Green Shopping Centre in Dublin. The exhibition, which runs until Oct. 15, brought the famine experience front and centre for me. Between 1845 and 1851, approximately one million Irish people died of starvation or disease and a couple of million emigrated, many of them to Canada. Many of those were forcibly evicted by landlords spouting the free-market doctrine of laissez faire. The end result: an Irish diaspora that has produced a globe-scattering of something like 70 million people of Irish descent. The decades immediately after the famine brought mostly silence about that trauma. More recently, scholars and others have turned increasingly to the Great Hunger, as it is also called. Today in Dublin, you can see famine monuments in St. Stephen's Green and on the north bank of the Liffey. You can visit the marvellous EPIC: The Irish Emigration Museum. And you can spend an hour poking around on the Jeannie Johnston, a replica famine ship. If you have time for only one stop, the exhibition at St. Stephen's Green includes a 15-minute film that summarizes the saga. Millions displaced, not hundreds of thousands. Terrible to contemplate. Preparing to leave Dublin, all I can think about is how the Irish famine changed the world.
