Wilton Diptych. The Wilton Diptych is a small portable diptych of two hinged panels, painted on both sides, now in the National Gallery, London.
It is an extremely rare survival of a late Medieval religious panel painting from England. The diptych was painted for King Richard II of England, who is depicted kneeling before the Virgin and Child in what is known as a donor portrait.
He is presented to them by his patron saint, John the Baptist, and by the English saints King Edward the Confessor and King Edmund the Martyr. The painting is an outstanding example of the International Gothic style, and the nationality of the unknown artist is probably French or English.
The Wilton Diptych is painted on two panels of Baltic oak, set in frames of the same material and joined by two hinges so that it may be closed to protect the inner painting. The inner faces of the panels are in excellent condition for their age, though some glazes have been lost, but the outer faces have paint losses from handling.
The painting is in tempera, the ground paint being mixed with egg yolk and laid in thin glazes. The background and many details are inlaid with gold leaf and in places the panel has been tooled beneath the gilding to enhance the decorative quality. In the panel with the Virgin and Christ Child, the garments are universally blue, the pigment coming from the semi-precious stone lapis lazuli. Richard's robe
