[Vinograd, Thiengen 4 (with erroneous pagination); Mehlman 205.] Thiengen, Eliezer & Joseph ben Naphtali Hertz,1560. $10,000 - $15,000 ❧ ONE OF THE EARLIEST ASCHKENAZI SIDDURIM. The fourth of only six Hebrew books printed in 1560 in this small German town (today known as Waldshut- Tiengen) situated along the Swiss border in the province of Baden-Württemberg. All Thiengen Hebrew imprints are scarce - indeed all are entirely unknown to Adams’ comprehensive census of Hebrew Books held in Cambridge University Libraries. The press was shuttered by the leaders of the Swiss Confederation fearing that the Talmud might be printed there. The inclusion here of Pirkei Avoth has the accompanying commentary by Rashi, but of a different text to the standard commentary more commonly known. OF PARTICULAR NOTE are the important 16th-century manuscript glosses all written in a Kabbalistic vein. The scholar Rabbi Dovid Kamenetsky suggests that this volume most certainly belonged to R. Yeshaya Horowitz (the Shela’h HaKodosh) and that the marginalia might very well be in his hand.
