Colossal has reported on Ancestral Futures, the sweeping solo exhibition by Tomas Saraceno at Haus der Kunst in Munich. Spanning more than two decades of the artist's practice, the show takes as its central premise that the knowledge gained in the past is critical to understanding and creating a shared tomorrow. Born in Argentina and based in Berlin, Saraceno has built a multidisciplinary practice that plays with scale and spectacle to draw attention to the life-giving ecosystems in which everyone is bound, merging art, architecture and science into alluring, often participatory works. At Haus der Kunst, his ecological and collaborative projects take centre stage in a presentation that asks how enormous, systemic concepts such as space, time and matter might be rendered tangible and accessible. The spider and its web return as a central metaphor and material example of the networks that undergird life, earning Saraceno his reputation as the art world's favourite arachnophile. Interactive installations invite visitors to crawl through sprawling structures, while the decade-long Webs of At-tent(s)ion series welcomes several species of spiders into the museum to spin their sticky structures inside boxes. The continual return to the web, the report notes, is a clear reminder that all beings are connected and that nature's processes are cyclical. Exhibition views show Saraceno's collaborative works installed at Haus der Kunst, with photography credited to Agostino Osio and the museum, shared with permission. The exhibition positions the artist's ecological imagination as both retrospective and prospective: looking to ancestral and arachnid knowledge as a resource for envisioning a more just future.
