RARE third edition, dating from 1823, of the theological textbook written by the German-Jewish member of the Haskalah movement, Jehuda Löw Ben-Zeev. The book was meant to teach the basics of the Jewish faith and the Jewish religion in a catechistic manner. The book was revolutionary in several aspects: in its approach to readers of both genders, by utilizing Leibnizian logic as basis for Judaism, and by its strict adherence to Biblical scriptures only. This bilingual edition was aimed at a larger section of the population: the left pages are printed in Hebrew, and the right pages in Hebrew transliteration of German. 200x125mm. 227 pages. Marbled quarter-leather Hardcover. Cover worn and rubbed. Cover corners slightly tattered. Cover edges slightly loose from binding. Spine worn and bumped. Spine edges and hinges peeling. Humidity stains on few first and last pages. Previous owners` names on whitepages and title page. Pen inscription on rear whitepage. Few pages slightly torn, with tears taped together, not detracting from readability save the last page Hebrew side outer edge (damage to several letters of the text). Page 224 outer edge damaged (text slightly damaged). Pages yellowing, some pages slightly stained. [SUMMARY]: Despite of the mostly external damage and the wear sustained in the nearly two centuries since its printing, this rare Haskalah-era Jewish theological textbook is still in good reading condition.
