Job: A Masque for Dancing is a one-act ballet produced in 1931. The scenario is by Geoffrey Keynes, the choreography by Ninette de Valois, and the music by Ralph Vaughan Williams. The ballet is based on the Book of Job from the Hebrew Bible and was inspired by the illustrated edition by William Blake. The music was first given in concert in 1930 and the ballet had its stage premiere on 5 July 1931. It was the first ballet to be produced by an entirely British creative team. It was taken into the repertoire of the Vic-Wells Ballet and its successors, and has been intermittently revived.
