 The "Vestiarium" was the work of the dubious "Sobieski Stuarts" and has been proven to be a forgery and a hoax.A group of MacArthurs from the Isle of Skye were hereditary pipers to the MacDonalds, and this tartan shares the same basic form of the MacDonald, Lord of the Isles tartan.Another MacArthur tartan is the "MacArthur of Milton Hunting" tartan.
