The concept of the light steles goes back to the Sahara project that Heinz Mack first came up with in 1958. Based on the idea of a mirrored stele placed in a desert and catching the gleaming light making it a vibrating sun pillar. The first realized object in aluminum was on display in Paris in 1959. Numerous other variants in different materials follow, either free-standing or in transparent object boxes. Basicall, the steles are elongated versions of Mack’s light reliefs, that make the motion of light visible through reflection of bowed metal plates - an ambition that shows in all Heinz Mack’s art.
