Camden informs us that he instituted the custom of the flitch of bacon of Dunmow. He says: "On the Priory here" (Dunmow), "Robert Fitzwalter (a powerful baron in the time of Henry the Third) instituted a custom that whoever did not repent of his marriage, nor quarrelled with his wife within a year and a day, should go to Dunmow and have a gamon of bacon. But the party was to swear to the truth of it, kneeling upon two hard pointed stones set in the Priory churchyard for the purpose, before the prior, the convent, and the whole town." Sir Robert, Kt., his grandson, was summoned to Parliament by writ, 23rd Edward I. (1295) and died in 1325. In 1275 he alienated Baynard's Castle, by licence, to Robert Kilwardby, Archbishop of Canterbury, who removed hither the Dominican or Black Friars from Holborn, but took special care to reserve all the rights and official duties connected with his barony. In the year 1303, before Sir J. Blount, Kt., Lord Mayor, a specification of his duties to the City was drawn out, which he swore upon the Evangelists to observe, and to the utmost of his power to maintain the rights and liberties of the citizens. His privileges and immunities in connection therewith are also given, which were confirmed by Sir John on the part of the Corporation. As this document presents some curious features of London life in the beginning of the 14th century, it is given below _in extenso_. The Rights that belonged to Robert Fitzwalter, Chastilion and Banner-Bearer of London and Lord of Wodeham. "The said Robert and his heirs ought to be and are chief Banner-bearers of London in and for the Castlry which he and his ancestors have of Baynard's Castle in the said City. In time of war the said Robert and his heirs ought to serve the City in manner hereinafter written. "That the said Robert ought to come upon his Horse of Service, with 20 men at arms, mounted, harnessed with mail or iron, even to the great door of the Minster of St. Paul, with a Banner of his Arms displayed before him. And when he has thus come, then ought the Lord Mayor of London, with the Sheriffs and Aldermen, come on foot out of the Minster to the said door, with his banner in his hand, and the banner ought to be gules, an image of St. Paul d'or, the feet, hands, and head, argent, with a sword argent, in the hand of the said Image.
