Exceedingly Rare Hebrew Book by one of the First Rabbis, and great Spiritual Leaders of Lithuania PRINTED 1737. ORIGINAL. I could not locate any other copy of the book in the standard library catalogues including that of the Jewish Theological Seminary. No copies appear in the auction databases. The book: "Sefer Gaon Zvi " [Book of the Sage Zvi] Cum Licentia Superiorum, [Prague, 5497 [1737]. Folio, wide margins, handsome copy, some browning, 18th century paper boards, peeling to spine, Complete. R. Zvi-Hirsh Horovitz, rabbi in three communities of Keidan-Vizhun-Birzh. Resident in Keidan. Among the first rabbis in Zamut. Known to have been rabbi here sometime after R. Elyakim-Getsel or R. Yehoshua-Heshel . The strains of the rabbinate interfered with his studies, and he left for Zabludova (Poland) where he devoted himself to Torah. In Russia it often happened that family names were made from a first Jewish name, and from Hirsh could have come Hirshovitsh and translates into modern day Hirshovitz.
