The Hydrospatial City may well be Gyula Kosice’s defining work. Begun in 1946 and completed in 1972, this single-room installation features space-like sculptures that dangle from the ceiling, refracting light onto the floor. Kosice, who was born in Czechoslovakian in 1924, conceptualized and created the piece while living in Argentina, where he spent most of his life, and where he died as a citizen in 2016. In The Hydrospatial City, his aim was to imagine what architecture might look like in space—unconnected and floating but united by a formal aesthetic. (Considering humankind has yet to experiment with the idea, Kosice’s vision may well be spot-on.) This wasn’t Kosice’s only space-related work; he produced a variety of interactive sculptures from the 1940s through the 1980s, in which light and movement figured heavily. “Gyula Kosice: Intergalactic” also features a collection of these works. —Jack Sullivan
