The Wilton Diptych is a comprehensive account of one of England's greatest surviving medieval treasures, now in the collection of The National Gallery, London. The painting depicts King Richard II (1367-1400) being presented to the Virgin Mary and Christ by John the Baptist and two English Kings, revered as saints. The brilliant color and lavish use of gold give it the appearance of a luxury object, yet its primary function was religious, as an altarpiece for the king's private devotions. The author analyzes the iconography, historical context, style, materials, and techniques used to create this precious work, and discusses the likely identity of the artist and the possible evidence that this picture was known to and referenced by William Shakespeare in his play Richard II. Further study of the intricate detail, varied techniques, and decorative effects shows connections to French metalwork and manuscript illumination, while newly commissioned photography reveals exquisite details unseen by the naked eye.

A Closer Look is the new series title for the updated and refreshed National Gallery Pocket Guide range. The series has been enhanced with a stronger format, attractive design, new photography, and additional information. The philosophy of modern conservation is different from that of previous eras: the emphasis now is on long-term stabilization by methods that alter the structure of a painting as little as possible. Nevertheless, if paintings are obscured by discolored varnishes and old repaints, they are cleaned, and this has often led to anxiety and debate as long-admired images are transformed. A Closer Look: Conservation of Paintings discusses the material nature of paintings and the ways that they have changed, both naturally and at the hands of previous restorers. It also describes the main types of conservation treatment carried out on panel and canvas paintings and some of the complex issues involved in cleaning and restoration.
