Ipousteguy began making sculpture in 1949 and worked almost exclusively, and most notably, in that medium for the rest of his life. His early work was often characterized by a core abstract form that was seemingly surrounded by a fractured shell. He spoke of "breaking Brancusi's egg," in reference to the elegant forms and uninflected surfaces of Constantine Brancusi's sculpture. Cénotaphe represents the artist’s earlier work, before his shift to various representations of the human form. Its geometric, planar quality reflects Ipousteguy's affinity for open and penetrable sculptural spaces. A cenotaph is an empty grave, a funerary memorial to a person whose remains are elsewhere. Austere and calm, Cénotaphe evokes its subject as a meditative, elegiac metaphor.
