There can be scarcely a country in Europe (and further afield) where this story is not known in at least one form; usually several.  F.J. Child mentioned a number of Italian sets, in which the heroine's name is variously Monchesa (or Monchisa), Mampresa, Monferrina, and so on.   This earlier thread:  The Outlandish Knight  includes links to quite a lot of related material available online at -relatively- reliable sites.

We would all, I think, be very interested to see an Italian-language version (standard Italian or dialect, it doesn't matter) if you would like to post it here; even more so if you are able to give us a tune as well.  Thankyou for mentioning this; I look forward to hearing more.
