In accordance with the famous proclamation of Henry VIII. (Nov. 16, 1538) which enacted 'that Thomas Becket' should no longer 'be esteemed, named, reputed nor called a sayncte, but Bysshop Becket, and that his ymages and pictures through the hole realme shalle be putte downe,' etc., it was enacted in 1539 that this reverse of the common seal should be destroyed. 'The beautiful reverse of the common seal, after doing duty for over three centuries, was therefore broken up, and presumably its silver used to make a new matrix. This is of the same size as its predecessor, but, in accordance with the resolution, it bears for device simply the city arms, _argent a cross gules and in the dexter quarter the sword of St. Paul_, with helm, mantling and crest, _a dragon's wing expanded argent charged with a cross gules_. The legend is: _Londini. Defende. Tuos. Deus. Optime. Cives._'[267] In connection with the arms it may be noticed that the supporters which are usually described as griffins are really dragons, in allusion to St. George. CHAPTER IX _Officials of the City_ The chief of the officials of the City of London was for many years after the Conquest the Castellan and Bannerer. When William the Conqueror obtained possession of London he built a castle on the river at each end of the city, to intimidate the Londoners. The Tower was at the east end, and at the west end was what according to Dugdale was called at first _The Castle_. This was placed under the charge of Baynard, one of the Conqueror's followers, after whom it came to be known as Baynard's Castle. The hereditary office of Castellan was held by the family of Fitz-Walter, by virtue of their possession of Baynard's Castle, the key of the city. The duties attached to this office are among the most important and interesting in the story of mediæval London, and it is to be presumed that Baynard held the various privileges afterwards possessed by the family of Fitz-Walter, but no notice of this is recorded. Robert Fitz-Richard was the first baron by tenure. He is said to have been the younger son of Richard Fitz-Gilbert, ancestor of the Earls of Clare. He was steward to Henry I., from whom he obtained the barony of Dunmow, and the honour of the soke of Baynard's Castle, both which had been forfeited to the Crown in 1111 by reason of the felony of William, Baron of Dunmow, son of Ralph Baynard, the Norman associate of William the Conqueror, after whom the castle was named. In connection with this soke Robert held the hereditary office of Standard-Bearer of the city, the duties of which will be stated further on. He died in 1134, and was succeeded by his son, Walter Fitz-Robert. The latter's son was Robert Fitz-Walter, the most famous member of the family, and the one who transmitted to his descendants the permanent surname of Fitz-Walter.
