"MOONRISE. west. may" by Ugo Rondinone is a cast polyurethane sculpture that reflects the artist's ongoing exploration of natural phenomena and temporal cycles through abstract forms. Rondinone frequently uses industrial materials like polyurethane to create works that contemplate landscape, light, and the passage of time, often titling pieces with references to celestial events or seasons. This work exemplifies his practice of translating ephemeral natural moments into durable sculptural objects that invite viewers to reconsider their perceptions of the everyday world.
