From November 21, 2018, the Musée Barbier-Mueller will present an exhibition focused on asen, iron altars specifically those of the former kingdom of Dahomey. It will explore an array of issues important to our understanding of these striking sculptures. Key among these are artist hands, questions of use, the history of these arts, and how asen enhance our understanding of the broader regional history of the southern area of the Republic of Benin where they are found.
