Gustav Yom-Tov Eisenschloss

Gustav Yom-Tov Eisenschloss, a professor in the history and religious-studies departments, is Shmuel Ash’s teacher and scholarly mentor. His work on Jesus in Jewish sources predates Shmuel’s proposed thesis, and when Shmuel abandons the project, Eisenschloss responds not with indifference but with an urgent appeal to keep investigating. Through him, the novel joins the history of Jewish writing about Jesus to a small, revealing encounter between a determined scholar and a student who has lost confidence in his own idea.

Scholar and Mentor

Shmuel begins his master’s research on Jesus from a feeling of intellectual exhilaration, convinced that he has found a bold, original subject. As he follows the sources, however, he discovers that the central idea had already appeared before his birth, in the 1930s, in a footnote to a short article by Eisenschloss, his great teacher. The discovery turns the professor’s scholarship into the immediate cause of Shmuel’s disillusionment: the work Shmuel thought he had originated has already been anticipated by the mentor whose authority he respects.

Eisenschloss’s scholarship also belongs to a longer history of arguments over how Jewish sources described Jesus. He is identified as one of the modern scholars who regards the passage about Jesus in Josephus’s Jewish Antiquities as impossible for a Jewish author to have written in its surviving Christian-sounding form, and considers it likely that Christian hands rewrote and inserted the passage later. The disagreement between that version and the account attributed to Agapius, which presents Josephus as describing the beliefs of Jesus’s followers rather than affirming Jesus’s messiahship or resurrection, illustrates the textual problems that make Shmuel’s field both compelling and difficult.

Shmuel’s Withdrawal

About three weeks before Yardena’s wedding, Shmuel definitively gives up the thesis, which he had begun with extraordinary enthusiasm. The obstacle is not simply that the topic is difficult: his investigation has persuaded him that the supposedly new insight is not new at all. When, in early December, sleet begins to fall in Jerusalem, he informs Eisenschloss and his other teachers in history and religious studies that he is leaving his studies.

Eisenschloss is astonished. He urges Shmuel to reconsider, arguing that a Jewish perspective on Jesus could open fertile territory in the Talmud, the Tosefta, the Midrash, popular tradition, and medieval writing. He imagines important advances still to be made and warns that abandoning the inquiry halfway through will prove a serious mistake. His appeal suggests that he sees the subject not as exhausted by his own earlier footnote but as a broad field that Shmuel could continue to explore.

Concern and Personal Attachment

The professor’s insistence acquires a more personal note when he asks whether discreet help might be found if Shmuel is facing financial difficulties. He grips Shmuel’s hand so forcefully that the student’s fingers crack, then declares that they will not give up so quickly—not on Jesus, the Jews, or Shmuel. The research, in his formulation, is inseparable from his concern for the student, whom he hopes to guide back toward confronting his inner debt.

Outside the office, Shmuel smiles as he recalls student parties at which he used to impersonate Eisenschloss. His performance reproduced the professor’s sudden, cuckoo-clock-bird movements and his habit of addressing people in the didactic first-person plural, even when speaking to his wife in their bedroom. The recollection gives the encounter an affectionate comic counterpoint: Shmuel can recognize and imitate the professor’s mannerisms even as he is unable to accept the professor’s advice.

Place in the Novel’s Intellectual History

Eisenschloss’s brief appearance helps establish the distinction between a promising question and a genuinely new discovery. His earlier article has already touched the idea that excites Shmuel, but his response to the student’s withdrawal is to insist that the subject remains fertile across many kinds of Jewish sources. In that tension, scholarship is shown as neither private inspiration alone nor a closed store of established conclusions: a predecessor’s work can defeat a claim to originality while still inviting further inquiry.

The broader research follows Jewish encounters with Christian accounts of Jesus across periods and genres, including rabbinic passages that were later removed from many printed Talmud editions out of fear of Christian retaliation, medieval polemical writing, and Yehuda Arie of Modena’s argument that Jesus was a Pharisaic Jew who did not claim divinity. Eisenschloss is not credited with all these positions; rather, his own note is the discovery that first unsettles Shmuel, while his later encouragement points toward the much wider history the abandoned project might have pursued.
