Giulio Bartolocci OCist (1 April 1613 – 19 October 1687) was an Italian Cistercian Hebrew scholar and author of the four-volume Bibliotheca Magna Rabbinica.
Richard Simon, in writing in his Bibliothèque Critique about Bartolocci's work, says: Complaints were also made that he devoted space to refutations of Jewish arguments and that his translations from the Talmud were faulty.
It is not a mere bibliographic and biographic compilation, but contains also a number of dissertations on Jewish customs, observances, and religious ideas; on the Sambation, on the beginnings of Hebrew typography, and the like.
Some Hebrew treatises are reprinted in full; for example, "Alphabet of Ben Sira," "Megillat Antiochus," "Otiot de-R. Aḳiba," and a part of Eldad ha-Dani's mythical journey.
Adriaan Reland of Holland attempted to publish in Amsterdam such an extract of the Bibliotheca, but he failed to execute the plan, there appearing in print the biographies alone of such famous exegetes as Rashi, Abraham ibn Ezra, David Ḳimḥi, Levi ben Gershom, and Judah Abravanel, which were embodied in his Analecta Rabbinica (Utrecht, 1702).
