Founded in 1824 The National Gallery is situated in Trafalgar Square, London. 
The Wilton Diptych (detail) is a painting, carving or piece of metalwork on two panels usually hinged like a book. 
This diptych is thought to have been painted as a portable altarpiece for King Richard II. The artist is unknown and is so called because it came from a House in Wiltshire.
