'Nomads of Mauritania' aims at understanding the cultural identity (religious beliefs, language, values, relationships with others) of the Mauritanian nomads through their geographical environment, an original history, their lifestyle, caste system, diet, housing and crafts and how it is revealed by their art, materially expressed on the everyday objects and the body and defined for the first time as geometrical-abstract and respectively as ephemeral usual art and ephemeral living art.
