Shulchan Aruch Even HaEzer. Furth, [1760]. Tens of Handwritten Novellae and References
Shulchan Aruch Even HaEzer "Afi Ravrivei' with Chelkat Michokek and Beit Shmuel, Furth, [1760]. Tens of handwritten novellae and references, apparently written c. 1840.
[2], 192 leaves. 32 cm. Most of the glosses are clear and legible.
The leaves of the Shulchan Aruch are full of thousands of references, annotations and elucidations in an Ashkenazic hand by an anonymous gaon. Even a cursory glance allows one to appreciate the amazing erudition of the author who is familiar with halachic literature, primarily responsa literature. Note that he does not quote the Shu"t of Ashkenazic sages, only tens of responsa works from Sephardic and Italian sages. The author undoubtedly had an impressive library – rare for those times. His library included many more works of responsa than that of the author of the "Pitchei Teshuva".
These are not merely referrals to other works, but short summaries of what is written there. The author was undoubtedly an illustrious sage, teacher and posek halacha, who was an expert in marriage and divorce.
Unidentified author. Owner signatures on the title page and in the book itself:
On the title page, near the bottom of the image of Moses: צבי הירש..אבד"ק
Owner stamp on a number of locations in the book: יעקב אהרן ראבינאוויטש אב"ד ה [אוסטראווי]. This is the son of Admor Aryeh Mordechai Rabinowitz b"r Yehoshua Asher of Parisov the son of the Yehudi HaKadosh of Peshischa. The manuscript was definitely written earlier, perhaps by one of his forefathers. It was apparently written between 1825-1865 (indicated by some comments like: Sha'arei Teshuva and Yad Efraim which were reprinted, etc.).
