Hill's poetry encompasses a variety of styles, from the dense and allusive writing of
King Log (1968) and
Canaan (1997) through the simplified syntax of the sequence "The Pentecost Castle" in
Tenebrae (1978), on to the more accessible poems of
Mercian Hymns (1971), a series of 30 poems (sometimes called "prose-poems", a label which Hill rejects in favour of "versets") which juxtapose the history of
Offa, eighth-century ruler of the Anglo-Saxon kingdom of
Mercia, with Hill's own childhood in the modern Mercia of the
West Midlands.
Seamus Heaney said of Hill: "He has a strong sense of the importance of the maintenance of speech, a deep scholarly sense of the religious and political underpinning of everything in Britain." Kenneth Haynes, editor of
Broken Hierarchies, commented: "the annotation is not the hard part with Hill's poems... the difficulty only begins after looking things up". Elegy is Hill's dominant mode; he is a poet of phrases rather than cadences. Regarding both his style and subject, Hill is often described as a "difficult" poet. In an interview in
The Paris Review (2000), which published Hill's early poem "Genesis" when he was still at Oxford, Hill defended the right of poets to difficulty as a form of resistance to the demeaning simplifications imposed by 'maestros of the world'. Hill was consistently drawn to morally problematic and violent episodes in British and European history and has written poetic responses to the
Holocaust in English, "Two Formal Elegies", "September Song" and "
Ovid in the Third Reich". His accounts of landscape (especially that of his native Worcestershire) are as intense as his encounters with history. Hill has also worked in theatre – in 1978, the
National Theatre in
London staged his 'version for the English stage' of
Brand by
Henrik Ibsen, written in rhyming verse. Hill's distaste for conclusion, however, has led him, in 2000's
Speech! Speech! (118), to scorn the following argument as a glib get-out: 'ACCESSIBLE / traded as DEMOCRATIC, he answers / as he answers móst things these days | easily.' Throughout his corpus Hill is uncomfortable with the muffling of truth-telling that verse designed to sound well, for its contrivances of harmony, must permit. The constant buffets of Hill's suspicion of lyric eloquence—can it truly
be eloquent?—against his talent for it (in
Syon, a sky is 'livid with unshed snow') become in the poems a sort of battle in style, where passages of singing force (
ToL: 'The ferns / are breast-high, head-high, the days / lustrous, with their hinterlands of thunder') are balanced with prosaic ones of academese and inscrutable syntax. In the long interview collected in
Haffenden's
Viewpoints there is described the poet warring himself to witness honestly, to make language as tool say truly what he believes is true of the world. ==Criticism==
