Seder HaDoroth
The Seder HaDorot or "Book of Generations" by Lithuanian Rabbi Jehiel Heilprin is a Hebrew-language chronological work that serves as a depot of multiple Hebrew language chronological books and manuscripts. The work presents all given dates in the Hebrew Calendar format.
As well, Heilprin analyzed alternating and sometimes conflicting dates to produce a final decision and/or at times presents two plausible dates for a given event.
Composition
This work consists of three independent volumes or parts:- The first of these, entitled Yemot 'Olam, is a history from the Creation down to his own time. The author always endeavors to give, by means of calculation, the dates of Biblical personages. He bases his work on the Yuḥasin of Abraham Zacuto, on the Shalshelet HaKabbalah of Gedaliah ibn Yaḥya, and on the Ẓemaḥ Dawid of David Gans. It seems that this first part was written when the author was still young, for the last event which he registered was one occurring in 1697.
- The second part, Seder HaTanna'im WehaAmora'im, contains lists of the Tannaim and Amoraim in alphabetical order with their dates.
- The third part is a kind of catalogue containing first the names of all the authors, then those of their works, both arranged in alphabetical order. Heilprin based this part on the Sifte Yeshenim of Shabbethai Bass, but added a great number of other titles. He states in the preface the many advantages of a knowledge of the chronological order of the Talmudists, which indeed in certain cases is absolutely necessary.
Of Heilprin's numerous other works mentioned in the Seder HaDorot, the only one which has been published is Erke HaKinnuyim, a dictionary of synonyms and homonyms occurring in the Bible, Talmud, and other works, chiefly cabalistic.
