Tucked behind the Summertown Library, in South Parade, lies the Turrill Sculpture Garden, created to celebrate the Millennium. It's a delightful space, best described as an unexpected oasis in the middle of a bustling shopping centre, which offers a tranquil place for visitors to sit and read, or just ponder on the state of the universe. Five talented letter cutters have now carefully placed their work among the foliage for an exhibition, Words Set In Stone, which remains on show until September 20.

The first piece of work visitors will encounter is All shall be well, the famous words of Julian of Norwich, carved on limestone by Pip Hall and standing on a bed of pebbles over which water ripples. Bil Brown, who began carving in 1949, and is still carving now, gives us The Quick Brown Fox Jumps Over the Lazy Dog (pictured), a line familiar to all those taught to touch type in the traditional way. He has worked this on slate and set the words and the pictures of both dog and fox in gold. Bernard Johnson, who took up stone carving as a hobby in 2000, developing it into a career three years later, has nine pieces on show, including the Italic Alphabet nicely worked in French limestone.

Giles Macdonald worked in Portland stone for his piece which announces that The Earth Too is a Goddess. John Neilson gives us And in that place our shadows run.

This exhibition will be officially opened by the very talented Oxford poet Jenny Lewis, who will read some of her poems in the garden tonight between 6pm and 8pm.
