Iain Sinclair Black apples of gower

Iain Sinclair, the celebrated author and psycho-geographer, walks back along the blue-grey roads and cliff-top paths of his childhood in south Wales, rediscovering the Gower peninsula.

Provoked by the strange and enigmatic series of paintings Afal du Brogwyr (Black Apple of Gower) made by the artist Ceri Richards in the 1950s, Sinclair leaves behind the familiar murky elsewheres of his life in Hackney, London, carrying an envelope of photographs and old postcards, along with fragments of memory.

He soon realises that a series of walks over the same ground - Port Enyon Point to Worm's Head have become significant waymarks in his life.

His recollections of a meeting with the poet Vernon Watkins, the art of Richards and the poetry of Dylan Thomas lead him to his final quest, the Paviland Cave where in 1823 human remains 36,000 years old were discovered.
