What is the author's style in Wandering Willie's Tale by Walter Scott?

Wandering Willie mentions at one point that he has heard this story told many times, and the impression conveyed is that of a folk tale handed down through the generations. The story presents itself as part of an oral tradition among ordinary folk, not the work of an individual author. That the story is told in Scots-English dialect reinforces its folk nature and helps transport the reader from the modern rationalistic world to a world of legend in which mysterious, supernatural events can occur.
