La Follia chord peogression is usually written as:
i - V7 - i - VII - III - VII - i - V7 (first eight bars)
i -V7 - VII - III - VII - i,V7 - i (second eight bars)
I can understand how this progression works for the most part but I don't really understand the motion VII - i from the point of view of classical functional harmony. Is there any explanation for its use from this point of view? (I'm not looking for an analysis from the point of view of popular music or jazz, I'm aware of some ways to rationalize the progression from those standpoints).
