The arms of Lord Lurgan (granted or confirmed 1840) afford another instance of a chapeau of unusual colour, his crest being: "Upon a chapeau azure turned up ermine, a greyhound statant gules, collared or." There are some number of cases in which peers whose ancestors originally bore their crests upon a wreath have subsequently placed them upon a chapeau. The Stanleys, Earls of Derby, are a case in point, as are also the Marquesses of Exeter. The latter case is curious, because although they have for long enough so depicted their crest, they only comparatively recently (within the last few years) obtained the necessary authorisation by the Crown. At the present time the official form of the chapeau is as in Fig. 663, with the turn up split at the back into two tails. No such form can be found in any early representation, and most heraldic artists have now reverted to an earlier type. Before leaving the subject of the cap of maintenance, reference should be made to another instance of a curious heraldic headgear often, but _quite incorrectly_, styled a "cap of maintenance." This is the fur cap invariably used over the shields of the cities of London, Dublin, and Norwich. There is no English official authority whatever for such an addition to the arms, but there does appear to be some little official recognition of it in Ulster's Office in the case of the city of Dublin. The late Ulster King of Arms, however, informed me that he would, in the case of Dublin, have no hesitation whatever in certifying the right of the city arms to be so displayed (Plate VII.). In the utter absence of anything in the nature of a precedent, it is quite unlikely that the practice will be sanctioned in England. The {382} hat used is a flat-topped, brown fur hat of the shape depicted with the arms of the City of Dublin. It is merely (in London) a part of the official uniform or livery of the City sword-bearer. It does not even appear to have been a part of the costume of the Lord Mayor, and it must always remain a mystery why it was ever adopted for heraldic use. But then the chain of the Lord Mayor of London is generally called a Collar of SS. Besides this the City of London uses a Peer's helmet, a bogus modern crest, and even more modern bogus supporters, so a few other eccentricities need not in that particular instance cause surprise. {383} CHAPTER XXIV THE MANTLING OR LAMBREQUIN
