When I was growing up, my grandmother had a book on Scottish folk tales. It was a hardcover, with a whitish cover; illustration on the front cover was of a little old scribe like fellow, seen from the back, with a tam and a candle as he wrote.
The massively prolific old-timey Scottish collector of folk tales was Andrew Lang. Doing a Google image search on his name, etc., throws up endless examples of his book covers. I’d suggest scrolling through those to see whether anything rings a bell.
been following the different links, but haven’t found it so far.
i remember that it had a couple of tales about Sir Michael Scot in it; one about how he lost his shadow to the Devil, and another about how he cursed some farmers into dancing for failure to feed him once.
Being an Ontario boy can be helpful, I thought I remembered that book from a primary school library or something. I put a few keywords into google search and there it was.
