Barbus Müller” are anonymous artworks, which certainly have a French origin. Usually carved in granite, Volvic stone or basalt, these sculptures of 60 to 70 centimetres high represent stylized characters whether they are male (Les Barbus) or female (Les Vénus). These two-headed creatures are equipped with a prominent head where the eyes and mouth have an important place, which reminds the monoliths of Easter Island. The name of these characters comes from the name of the Swiss collector Josef Müller who discovered them in 1940 in an antique dealer. In 1947, Jean Dubuffet publishes his first booklet “L’Art Brut” on these statuaries.
