Steles, rotors, light sculptures and monumental works for the public space ? over the past 20 years the range of Heinz Mack?s sculptures has remained as comprehensive as it is diverse. He has created spectacular works like "The Sky over Nine Columns" in Venice in 2014. This lavish catalogue raisonné documents Mack?s sculptures between 2003 and 2020.00Apart from the range of materials such as natural stone, metal, wood, plaster, sand and glass, the sculptures of Heinz Mack are characterised by their elemental, powerful nature in connection with light and/or movement. In his late works the artist continues to develop themes from earlier work phases, such as the stele with its ability to transform light and determine space. Typical of the last twenty years is his increased focus on sculptures of stone like granite or marble, sometimes of monumental size.
