Quantum Cloud XV is a monumental stainless steel sculpture from Antony Gormley's celebrated Quantum Cloud series, created in 2000. The work features an explosive network of linear steel elements that coalesce into a dense, anthropomorphic core, embodying Gormley's exploration of the relationship between the human body and space. Part of the prestigious Doris and Donald Fisher Collection at SFMOMA, this large-scale sculpture represents a pivotal moment in Gormley's practice of creating complex, three-dimensional forms that challenge perceptions of mass, volume, and presence.
