possible question for part 1:
While other texts in Ashmole 61 incorporate some elements of the supernatural into the plot, the themes in Sir Orfeo seem to rely heavily on the existence of the Faery Kingdom. How does this magical realm and its characters function in the romance? What purpose does it serve?
This would suit Part 1, indeed, and the focus on function and purpose is something to bear in mind in considering the role of the supernatural elsewhere in the manuscript, too–in both overtly Christian terms and in more ambiguous cases (as with Orfeo). I think taking a look back at the second half of the manuscript, especially, with an eye to the involvement of the supernatural would be a useful study tool.
