Anyone who has given the British Museum’s Sainsbury Gallery of African Art anything more than a very brief visit (in and out to gawk at the Benin bronzes) will surely have admired the extent to which the curators have attempted, through a series of short films on loop, to show how some of the artefacts on display have been used – and the lives they continue, in many cases, to lead in West and Central Africa in particular. Viewers can learn about pottery, bronze casting, the rivalries between asafo banner-bearing Fante youth companies in Ghana and, most memorably for me, about the extraordinary masquerades performed by secret societies.
