Paris Post War: Art and Existentialism 1945-55

'How can a wall help

A wounded man?

And yet

During a battle some always come

And put their backs to them

As if death, in that way

Allowed them to die

More at their leisure

And with a little liberty.'

From Les Murs by Jean Dubuffet and Eugene Guillevic (Les Editions du Livre, Paris, 1950). Translated by Barbara Wright.

Paris Post War: Art and Existentialism 1945-55 at the Tate Gallery until 5 September.
