In 'The Stairwell', his tenth collection, Michael Longley's themes and forms reach a new intensity. The second part of the book is a powerful sequence of elegies for his twin brother, Peter, and the dominant mood elsewhere is elegiac. The title poem begins: 'I have been thinking about the music for my funeral.' The two parts are also linked by Homer. Longley is well-known for his Homeric versions, and the Iliad is a presiding presence - both in poems about the Great War and in the range of imagery that gives his twin's death a mythic dimension. Yet funeral music can be life-affirming. Longley has built this collection on intricate doublings, not only when he explores the tensions of twinship. The psychologically suggestive word 'stairwell' is itself an ambiguous compound.
