With the simple words
the artist evokes The Crucifiction of Christ.
The Question Mark Inside was commissioned by Dean and Chapter of St Paul's Cathedral as the first large-scale public artwork in the cathedral's history.
It was created for all Londoners, regardless of belief, to mark the 300th anniversary of the topping-out of Sir Christopher Wren's architectural masterpiece in 2008.
The work posed the simple question, 'What makes life meaningful and purposeful?' and invited responses from the public during the anniversary year.
Inevitably, the artist investigated belief, non-belief and the politics of both positions.
The resulting texts, from the domestic to the sexual to the sublime, were projected onto the exterior of the cathedral dome, the West Front at Ludgate Hill, and the interior of the Whispering Gallery.
