The 13th Century roll of arms had been auctioned by Southbys to a foreign purchaser, but the sale was blocked by the British Culture Ministry.
The Dering Roll was produced in England in the last quarter of the 13th century. It is eight and a half feet long and contains the coats of arms of approximately one-quarter of the English baronage of the reign of King Edward I. As the earliest surviving English roll of arms it is a key document of medieval English knighthood. As a statement of the knights who owed feudal service to the constable of Dover Castle, it carries outstanding local as well as national significance.
