'Cogent and playful expressions of Eliasson's exploration of gravity are to be found in works like The moss valley series. [Here,] the horizon line is pushed all the way to the top of the frame, so that we have the feeling of sinking into the earth, [especially as] we know Eliasson was standing on soft ground.'
