The American artist James Turrell is famous for his Skyspaces. A Skyspace is chamber with an opening to the sky. Turrell bathes the roof with light that subtly changes colour, which affects our perception of the colour of the sky itself. Julian May travels to ARoS, the Art Museum in Aarhus, Denmark to meet James Turrell as he prepares his latest SkySpace, entitled As Seen Below – The Dome. It is a monumental work, which from the ground outside looks like tumulus, an ancient a grass covered burial mound. To experience the work Julian goes through an underground tunnel that brings him into the huge domed space flooded with changing coloured light. Through the opening the sky appears at once immensely deep, yet close.
