In all of his work, Alan Saret shows great interest in using mutable material to create non-static sculptures. As he stated: “The flexure of each material draws a line in space which corresponds identically to its physical properties. Nature, therefore, draws the final line in the art.” In The Hole at P.S.1, Fifth Solar Chthonic Wall Temple, sunlight is the natural medium that influences the general shape of the sculpture. As part of MoMA PS1’s initial exhibition Rooms, this site-specific installation consists of a carefully sized and shaped hole dug out of the brick wall. When the sunlight faces the exterior side of the building, a focused stream light enters the hallway and shines down to the floor.
