Besides their great value as historical monuments, monumental brasses are interesting as authentic contemporary evidence of the varieties of armour and costume, or the peculiarities of palaeography and heraldic designs, and they are often the only authoritative records of the intricate details of family history. Although the intrinsic value of the metal has unfortunately contributed to the wholesale spoliation of these interesting monuments, they are still found in remarkable profusion in England, and they were at one time equally common in France, Germany and the Low Countries. In France, however, those that survived the troubles of the 16th century were totally swept away during the Reign of Terror, and almost the only evidence of their existence is now supplied by the collection of drawings bequeathed by Richard Gough to the Bodleian Library.
