(Chidushim on Torah and Talmud).

A noteworthy work of rabbinic scholarship containing intricate, erudite and sharp pilpulim. The anonymous author was clearly a profound Talmid Chacham who focuses here on the most difficult Talmudic topics, often in great depth. He frequently cites and refers to his other works on Talmud. Although the work is anonymous, the verso of p. 287 has a manuscript note in another contemporary hand: “Kethivath Yado Hamaor Hagadol Hamefursam Mo’ Gershon Nero Yair Veyizrach.” Plus in German “Gerschon Michel Jud. Rabiner … in Frankfurt (?)”. The manuscript was written in the later half of the 18th century as the author cites Kreithi Upleithi by R. Jonathan Eybuschetz (published in Altona 1763) at bottom of p. 120 and p. 140.
