This is a detailed catalogue raisonné of eighty-eight fifteenth and sixteenth century South Netherlandish paintings, with an introductory essay on the formation of this section of the royal collection between the sixteenth and nineteenth centuries. The principal pictures are of the highest importance: the Trinity Panels by Van Der Goes, Federico da Montefeltro attending a Reading attributed to Justus of Ghent, Quinten Metsys' portrait of Erasmus, Gossaert's Adam and Eve and his Children of Christian II of Denmark, and Bruegel's Massacre of the Innocents. There are interesting paintings, several previously unpublished, by less well-known artists and a large number of royal portraits. This is an important but little-known group of pictures, whose history is interesting in itself and casts important light on the development of taste at the British courts.
