Sepher Yetzirah [“Book of Creation”; cosmogony]. With commentaries of Abraham ben David of Posquieres (RABaD) and Moses Nachmanides (RaMBaN).

<<OF THE UTMOST RARITY. ONLY KNOWN EXTANT COPY.>> <<FROM THE LIBRARY OF THE LATE SCHOLAR AND BIBLIOGRAPHER RABBI CHAIM LIBERMAN>> (Librarian and Secretary of R. Yosef Yitzchak Schneerson of Lubavitch). Liberman writes in his Ohel Rochel Liberman (Vol. I, p. 352-54) that he came across an entry by Shabthai Bass in his Sifthei Yeshanim referring to a Prague edition of the Sepher Yetzirah. “For many years, I searched for this Prague edition without success, for I did not find it (recorded) in any of the catalogues of the famous libraries. Until once a book dealer offered me a copy of the Sepher Yetzirah which had the place of printing on the title page removed and in its place was handwritten “Venice.” When I saw the name of the printer as Abraham Heida… I knew this was (the elusive) Prague edition. I fell upon this discovery and purchased it.” Later, Liberman was disappointed that his Prague treasure included the first sixteen leaves and f. 22 only. The rest of the text in this volume is from the first Mantua edition. Liberman identified the publication date via the introduction here, where the printer states that over 62 years have passed since the Sepher Yetzirah was first published - thus dating this Prague edition to 1624-25. He notes that the title-page of this copy had explicitly stated “Nidfas Sheniah” (second edition), but was altered to read “Nidfas BeVenetsiah.” <<The only extant copy of the second edition of the Sepher Yetzirah. @
