British-born, German-based sculptor Tony Cragg rose to prominence in the 1980s as a leading voice in the cohort known as New British Sculpture. Seeking a new, European sensibility, homegrown out of the continent’s neo-avant-garde positions, this group, which also included Antony Gormley and Anish Kapoor, took inspiration from a broad range of practices. But the awe-inspiring technique of their work—Kapoor’s mirrored surfaces, Gormley’s cubistic distillation of space into three-dimensional grids, or Cragg’s fractal-like complexity—have tended to overshadow their art historical roots. In the case of Cragg, whose 2005 sculpture Discussion is up for auction on June 25th by the Swiss auction house Koller, this genealogy forms the basis for the artist’s iconic style, often in surprising ways.
