Constantin Brâncuși created the first version of Bird in Space in 1923.
Bird in Space is a series of sculptures in which Brâncuși reduced a bird to a tall, polished form that suggests upward flight rather than depicting feathers or anatomy. The first version dates from 1923, and Brâncuși continued developing the idea in additional marble and bronze works.
The sculpture became central to a famous 1927 American customs case. Officials initially classified a bronze version as a manufactured object rather than a work of art because it did not resemble a recognizable bird. The court ultimately accepted the sculpture as art, helping broaden public discussion about modernist abstraction.
Brâncuși’s smooth surfaces, tapered silhouette, and emphasis on pure form reflect his search for essential qualities rather than literal representation. Bird in Space is therefore not one unique object but a related series of versions made over time.
