The poems in Seamus Heaney's collection The Spirit Level keep discovering the possibilities of 'a new beginning' in all kinds of subjects and circumstances. What is at stake, in poem after poem, is the chance of buoyancy and balance, physical, spiritual and political. Private memories, classical scenes, humble domestic objects - a whitewash brush, a sofa, a swing - are endowed with talismanic significance, while friends and relatives are invoked for their promise and steadfastness.
