A choral work inspired by the photograph of the same name taken from lunar orbit in 1968, considering the positive and negative sides of the human race's mastery and control of the world. The work was commissioned by the UK choir Ex Cathedra for its 40th anniversary, which fell in the same year (1969) as the 40th anniversary of the Moon landing. It was written for 40-part choir, on the model of Thomas Tallis's famous Spem in alium.
