Alfred Lord Tennyson is now remembered – if he is remembered at all – as the gloomily bearded Poet Laureate, author of such clanking Victorian works as ‘The Charge of the Light Brigade’, and the mournful author of the lugubrious elegy In Memoriam. In this dazzling new biography, Richard Holmes reawakens this somnolent Victorian figure, brings him back to sparkling life, and unexpectedly transforms him.

The brilliant child of an obscure dysfunctional Lincolnshire family, terrorised by a drunken father, torn by unhappy love affairs but sustained by vivid friendships (especially that of Edward FitzGerald, the author of ‘Omar Khayyam’) Young Tennyson emerges in his first forty years as a memorable poet, hypnotically musical (‘The Lady of Shalott’) yet intensely engaged with the new astronomy, geology, biology – and even the psychiatry – of the age before Darwin.

Tennyson’s imagination and intellect were haunted by the eruption of three new fundamentally transformative scientific ideas – biological evolution, the notion of a godless, unpitying universe and of planetary extinction.

Tennyson’s work during these ‘vagrant years’ is suffused with an unsuspected and strangely modern magic. Holmes’s extraordinary biography allows us to witness Tennyson wrestling with mind-altering ideas of geology and deep time, the vastness, beauty and terror of the new cosmology, and the challenges of social revolution. And how these inspired him to grapple with the idea of human mortality, the threat of suicide and depression, the struggle between love and loneliness, agnosticism and belief.
