Discussions of cross-dressed medieval romance heroines commonly mention the tale of Grisandole. For the sake of completeness, I tracked down this comprehensive analysis of the tale. Although Grisandole's cross-dressing doesn't include any of the accidental homoeroticism of many such tales, this article is a great example of how medieval romances were built up out of pre-existing material, and how many parallel versions of a core tale co-existed, swapping elements out or in depending on the local taste.
