Drumcliffe, County Sligo, isn’t where the poet W. B. Yeats popped his clogs – the south of France has that honour – but it is where that most eloquent of Irishmen ended up. Or is it? Dying in 1939, he was buried in France for nine years before his wish to be buried within sight of the Benbulben Mountains of Ireland was respected. Rumours have since gone round that the remains beneath his epitaph “cast a cold eye on life, on death, horseman, pass by” are those of a French dentist, not the Irish wordsmith.
