A short but, as always with this author, superbly researched account of a catastrophic period in Irish history, still little remembered. As Dickson points out, at least an eighth of the country's population perished in a 21-month period, proportionately far higher than the much longer Great Famine of the following century. If the scale of the disaster has not resonated as strongly in subsequent years, Dickson suggests that this is because the unprecedented weather was blamed for the human suffering it caused, and - notwithstanding the distinctly varied responses of gentry and clergy - it touched all classes keenly. The 19th century famine, by contrast, was (rightly) regarded as an affront to decency and a wholly unacceptable failure by government in an era of prosperity and plenty. Though a concise monograph, Arctic Ireland nonetheless provides much food for thought.
