British Library; Until 19 September
This new exhibition - subtitled "Power, Propaganda and Art" - points to the varied functions of maps. In fact, most of the maps here seem to emphasise both their aesthetic magnificence and their function as symbols of power. Vast canvases of expensive thread, continents outlined in gold leaf and portraits of kings adorning the tops of their colonial conquests need little explanation. The structure of the exhibition, portioned into "throne room", "bedchamber" and other rooms in a royal court, adds to this effect.
