At the heart of eighteenth-century Jewish Italy stands a figure and a work that are inseparable: Isaac Ḥizqîyȧh ben Samuel Lampronti and his encyclopedic monument, the Paḥad Yiṣḥaq ("the Fear of Isaac," an allusion to the verse in Genesis where Jacob swears "by the Fear of his father Isaac"). The title, chosen with an elegance characteristic of Italian erudition, plays on the author's first name as much as on the biblical motif. Rabbi Isaac Lampronti, the eighteenth-century author of the Talmudic encyclopedia Paḥad Yitshak, lived in Ferrara, Italy, and was a striking example of the singular style of Italian Jewish scholarship in all its eclecticism and erudition.

The work occupies a singular place in Jewish intellectual history: it constitutes the first major attempt to systematize the whole of halakhic knowledge in an alphabetical form, anticipating by more than a century the great modern encyclopedic undertakings. The first major Jewish encyclopedia in alphabetical arrangement was the Paḥad Yiẓḥak (13 vols., 1750–1888) by Isaac ben Samuel Lampronti, a physician of Ferrara, who worked on this reference work covering the Talmud, rabbinic literature, and responsa.

The present volume traces, through archive and research, the journey of a man who was at once rabbi, physician, and pedagogue, and the genesis of a work whose encyclopedic ambition reflects the dual culture—sacred and secular—of the Italian Judaism of the Enlightenment.

Isaac Lampronti was born into the Jewish community of Ferrara, a city of the Papal States where Italian, Sephardi and Ashkenazi traditions had intermingled over the centuries. Isaac Lampronti was born on 3 February 1679 and died on 16 November 1756; he was an Italian rabbi and physician, best known as the author of the rabbinic encyclopedia Paḥad Yitzḥak, born in Ferrara.

The family roots extend beyond the peninsula, into the Mediterranean East. Lampronti was born in Ferrara; his great-grandfather, Samuel Lampronti, had emigrated from Constantinople to Ferrara in the sixteenth century. His father, a man of means, died when Isaac was six years old. This Constantinopolitan ancestry places the family within the vast network of Sephardi and Levantine diasporas that flowed through northern Italy in the early modern period.

The child was entrusted very early to traditional instruction. Isaac was sent to school in his eighth year, his teachers being Shabbethai Elhanan Recanati and S. E. Sanguineti; in his fourteenth year he went to Lugo, to the school of R. Manoah Provençal. The very name Lampronti, Italian in sound, and the use of the two Hebrew given names Yiṣḥaq Ḥizqîyȧh — Isaac Hezekiah — illustrate the dual belonging, local and Jewish, that would mark his whole life and work.

Lampronti's trajectory embodies one of the most distinctive traits of Italian Judaism: the conjunction of talmudic science and medical science within a single person. After his rabbinic studies, he made his way to the illustrious university of Padua. Lampronti studied under the great Italian rabbis of his generation: Manoah Provençal in Lugo, Judah Briel in Mantua, and Isaac Ḥayyim Cantarini in Padua; in addition, he studied philosophy and medicine at the university of Padua.

Padua then represented a unique crossroads for the Jewish scholars of Europe. Padua was an important center of Hebrew studies on account of its rabbinic academies and because Jews were drawn there from all over Europe to study at its university, which was open to Jews. This exceptional openness — rare in the Europe of the time — allowed generations of rabbi-physicians to combine mastery of talmudic law with that of the natural sciences.

Returning to his native city, Lampronti placed his knowledge at the service of the community. Isaac Hezekiah ben Samuel Lampronti (1679–1756), rabbi, physician, and educator, returned to Ferrara at the age of twenty-two and began teaching in the talmud torah of the Italian community, then also in that of the Sephardic community. Medical practice remained for him a vocation as much as a profession. Notwithstanding his other occupations, he continued to practice medicine, visiting his patients early in the morning, because, he said, the physician has a surer eye and judges his patient's condition better after the night's rest; he enjoyed a great reputation as a physician, and his contemporaries generally added to his name the epithet of "famous physician."

Even before becoming the author of an encyclopedia, Lampronti was an educator concerned with transmission. His return to Ferrara placed him at the center of the community's scholastic and religious life. Having returned to Ferrara at the age of twenty-two, he began teaching in the talmud torah of the Italian community and later also in the talmud torah of the Sephardic community; he introduced numerous improvements to the curriculum.

This reformist and pedagogical dimension casts a particular light on the great encyclopedic project: the Paḥad Yiṣḥaq is not only a scholarly summa, but also an instrument of transmission, conceived by a man whose entire life was devoted to teaching. The figure of the rabbi-physician of Ferrara embodies the synthesis characteristic of his milieu. No Jew better illustrated this fusion of halakhic and scientific expertise than Isacco Lampronti (1679–1756), the most illustrious Jewish citizen of Ferrara; educated both in rabbinic science and in medicine, Lampronti had studied with the distinguished rabbi-physician Isaac Cantarini, and then, like many of his Jewish contemporaries, had completed his medical studies at the University of Padua. It was this combined authority that gave his work its credibility and its depth.

Lampronti's masterwork far surpasses everything else he accomplished. R. Lampronti's principal reputation rests upon his monumental Paḥad Yiṣḥaq, of which he himself wrote two editions, the first comprising 120 and the second 35 manuscript volumes. The scale of this manuscript labor bears witness to a lifelong discipline.

The structure of the work makes it a true reasoned dictionary of Jewish law. The Paḥad Yiṣḥaq is the most complete and best-known encyclopedia in the field of halakha; it is arranged alphabetically, each entry including material from the Mishna, the Talmud, the posekim, the rishonim, and the responsa literature; it gives particular weight to the responsa literature of the Italian rabbis. This attention to the Italian decisors makes the Paḥad Yiṣḥaq an irreplaceable source for the history of Judaism in the peninsula, preserving responsa and rulings that, without it, might have vanished.

The ambition of the project is summed up by contemporary scholarship. Isaac's Fear (Pachad Yitzhak) was the first multi-volume encyclopedia of Jewish law, compiled by Isaac Lampronti (1679–1756), rabbi and physician of Ferrara; David Malkiel's study explores the religious, cultural, and intellectual life reflected in the work.

The publication of the Paḥad Yiṣḥaq was an undertaking that extended far beyond the lifetime of its author, and whose vicissitudes attest both to the scope of the work and to the devotion of subsequent generations. Originally published for the letters "Aleph-Mem" in large folio volumes in various regions of Italy from 1750 to 1799, the letters "Nun-Taf" were first published in Lyck-Berlin from 1864 to 1888 by the Mekize Nirdamim society in smaller octavo volumes.

The publication schedule, spread over nearly one hundred and forty years, illustrates the difficulty of bringing such a publication to completion. The Paḥad Yiẓḥak comprises thirteen volumes published between 1750 and 1888. The first part appeared during Lampronti's lifetime or shortly thereafter, in Italy; the second half of the alphabet awaited the nineteenth century and the effort of the learned society Mekize Nirdamim, devoted to the publication of unedited Hebrew manuscripts.

The details of the final publications reveal a truly transnational collective work. The Paḥad Yiṣḥaq of Rabbi Yitzchak Lampronti appeared in four volumes: letters Nun-Samech, Lyck, 1866-1885; letters Kuf-Resh, Berlin, 1855; letter Shin, Berlin, 1886; letter Taf, Berlin, 1887. Thus the encyclopedia of a physician of Ferrara, begun under the Papal States, was completed in the Berlin of emancipation and the Wissenschaft des Judentums, a sign of the work's European posterity.

Beyond its function as a register, the Paḥad Yiṣḥaq bears the imprint of a singular intellectual spirit, in which the author's scientific culture engages in dialogue with rabbinic tradition. The work is distinguished by its determination to harmonize divergent subjects and opinions. The Paḥad Yitzhak of Isaac Lampronti (1679–1756) of Ferrara, written in the eighteenth century, attests to an effort to integrate and mediate disparate traditions, to reconcile and accommodate conflicting juridical opinions and religious ideals — in short, an effort of tolerance.

This spirit of accommodation is not merely an encyclopedic method: it reflects the intellectual stance of a scholar trained both in Padua and in the rabbinic academies, capable of holding together Talmudic reasoning and naturalist observation. It was precisely this twofold competence that made him an exceptional figure. No Jew better embodied this fusion of halakhic and scientific expertise than Isacco Lampronti, the most illustrious Jewish citizen of Ferrara.

The intersection of science and tradition that runs throughout the work makes the Paḥad Yiṣḥaq far more than a mere instrument of consultation: it is a testimony to the way in which the Italian Judaism of the Enlightenment strove to think together fidelity to the Law and openness to secular knowledge.

The Paḥad Yiṣḥaq remains, in the history of Jewish literature, a foundational milestone. The first large-scale halakhic encyclopedia arranged alphabetically, it foreshadowed the vast undertakings of codifying knowledge that would characterize the modern age. The first great Jewish encyclopedia in alphabetical arrangement was the Paḥad Yiẓḥak of Isaac ben Samuel Lampronti, a physician of Ferrara, covering the Talmud, rabbinic literature, and responsa.

The man and the work merge together in Italian and Jewish memory: a rabbi-physician whose dual vocation embodied the ideal of a total knowledge, and whose encyclopedic monument preserved, in particular, the legal memory of the Italian communities. The Paḥad Yiṣḥaq is the most complete and best-known encyclopedia in the domain of halakha, giving particular importance to the responsa literature of the Italian rabbis. Born in Ferrara to a family that had come from Constantinople, trained in Padua, mourned in 1756, Lampronti left a work whose publication, completed in Berlin in 1888, alone speaks to the European reach of this "Fear of Isaac."
