a barony, the owner was given a chapeau or cap of maintenance as part of his armorial achievement on petitioning for the same. This chapeau is described as "gules doubled ermine" for barons in possession of the caput of the barony. An azure chapeau is appropriate for the heirs of ancient baronial families who are no longer owners of the estates. This chapeau was a relatively recent armorial invention of the late Lord Lyon Thomas Innes of Learney. Accordingly, a number of ancient arms of feudal barons do not display the chapeau, and now it is no longer granted. At the Treaty of Perth in 1266, Norway relinquished its claim to the Hebrides and Man, and they became part of Scotland. In 1292, Argyll was created a shire and "The Barons of all Argyll and the Foreigners' Isles", which had preceded the kingdom of Scotland, became eligible to attend the "Scots" Parliament – appearing in the record of the parliament at St. Andrews in 1309. Historically they have a chapeau, "gules doubled ermines", ermines being white tails on black. There is a unique exception: the Barony of the Bachuil is not of feudal origin like other baronies but is allodial in that it predates (562 A.D.) Scotland itself and the feudal system, dating from the Gaelic Kingdom of Dál Riata. In recognition as allodial Barons par la grâce de Dieu not barons by a feudal crown grant, the Baron of the Bachuil has the only chapeau allowed to have a vair (squirrel fur) lining. A chapeau, if part of an armorial achievement, is placed into the space directly above the shield and below the helmet. It may otherwise be used on a visiting card, the flap of an envelope, or to ensign the circlet of a crest badge as used on a bonnet. Feudo-baronial mantle Particularly Scottish in character is the feudo-baronial mantle or robe of estate - described as gules doubled silk argent, fur-edged of miniver and collared in ermine, fastened on the right shoulder by five spherical buttons Or. This may be displayed in a pavilioned form, draped behind the complete achievement of arms - or the armorial shield alone - tied open with cords and tassels, and surmounted by the chapeau. Again, Lord Lyon is no longer granting these heraldic mantles. Helmet The helmet is now the chief mode of recognition of a Scottish baron. The Lord
