I am sure that she never intended these passages to be perpetuated in her Medieval People and I have therefore done what I could to replace them with a reconstructed version of her first draft. The reconstruction had to be done from somewhat disjointed notes and cannot therefore be word-faithful. The readers must therefore bear in mind that the first two and the last page of the essay are mere approximations to what Eileen Power in fact wrote.
