Belfagor is an astronaut’s helmet on a sarcophagus plinth. It's the attempt to capture the space surrounding alpture and give nothingness a physical shape. Void has no boundaries, but even though the statue is solid it may give you a sense of it. The name is taken from an French TV series of the Sixties, Belphégor, le phantôme du Louvre, which haunts the Egyptian Collection of the Museum. 

Belfagor was carved by hand from shell limestone (pietra di Vicenza). The second, slightly modified version of the statue is made of polyurethane painted white.
