Get yourself a copy of "The Gaelic Otherworld" by the Rev. John Gregorson Campbell if you only buy one paper copy of a book this year Dodge. It's two older books put together, which have been archived, but the compilation version comes with an anthropological commentary by the School of Scottish Studies head prefessor. It analyses the stories to show the unsanitised version of how hard life was, and the things we told ourselves in stories just to be able to cope with them.
