Custom houses In old English law, a cocket was a custom house seal; or a certified document given to a shipper as a warrant that his goods have been duly entered and have paid duty. Hence, in Scotland, there was an officer called the clerk of the cocket. It may have given its name to cocket bread, which was perhaps stamped as though with a seal. Destruction The importance of the seal as a means of authentication necessitated that when authority passed into new hands the old seal should be destroyed and a new one made. When the pope dies it is the first duty of the Cardinal Camerlengo to obtain possession of the Ring of the Fisherman, the papal signet, and to see that it is broken up. A similar practice prevailed in the Middle Ages and it is often alluded to by historians, as it seems to have been a matter of some ceremony. For example, on the death of Robert of Holy Island, Bishop of Durham, in 1283, the chronicler Robert Greystones reports: "After his burial, his seal was publicly broken up in the presence of all by Master Robert Avenel." Matthew Paris gives a similar description of the breaking of the seal of William of Trumpington, Abbot of St Albans, in 1235. The practice is less widely attested in the case of medieval laypeople, but certainly occurred on occasion, particularly in the 13th and 14th centuries. Silver seal matrices have been found in the graves of some of the 12th-century queens of France. These were probably deliberately buried as a means of cancelling them. When King James II of England was dethroned in the Glorious Revolution of 1688/9, he is supposed to have thrown the Great Seal of the Realm into the River Thames before his flight to France in order to ensure that the machinery of government would cease to function. It is unclear how much truth there is to this story, but certainly the seal was recovered: James's successors, William III and Mary used the same Great Seal matrix, fairly crudely adapted – possibly quite deliberately, in order to demonstrate the continuity of government. A related practice of destruction is found among blacksmiths: their touchmark (a stamp used on the hot metal
