Sigurd, you will know Descripto Insularum Orcadiarum: by Jo Ben. Translation with notes published by Scottish History Society 1908 ppvi-xiii, 302-323. Earliest contemporary account of Orkney to which GMB referres in his 1952 brochure about Orkney, which later became the more elaborated Orkney Tapestry. I think it would be helpfull for the understanding of the text to have some of your comments on the notes shown there ... :-) Wolfgang
