I did learn several comments of Rishonim on a Suggia in Masechet Shabbath and read a footnote (from Harav Moshe Hershler) on the Ramban (Edition Hamachon Hatalmud Haisraeli).
He refers to a comment by Ran, Shita Leharan and Ritba. I understand that there is a discussion about the identity of the authors of the old edition of Chidushe Haritba, the new edition of Chiddushe Haritba (edition Mosad Harav Cook), the old edition of the Chiddushe Haran and the new (I have a new edition but older than the Mosad Harav Cook edition). Some experts attribute the old edition of Chiddushe Haritba to the Ran, the old Ran's Chiddushim to an unknown Rishon.
Can someone clarify the topic for me?
- Who wrote the old Chidushe Haritba and the new;
- Who wrote the old Chidushe Haran and the new?
- Is there still a controversy?
