Imaginary Space meets Actual Space in Thirteenth-Century Cologne: Eliezer Ben Joel and the Eruv
Bibliographic record
Abstract
Abstract Eliezer Ben Joel ha-Levi’s Laws of Eruv, a crucial text in the medieval history of the eruv, redefines ancient definitions of space to fit that of a medieval town. It uses talmudic terminology to describe medieval reality; it reinterprets this terminology to fit this reality; and rules in a way that enables the whole Jewish quarter to be seen as one private space. This ruling shows that in medieval Europe the eruv was redefined to encompass the entire Jewish neighborhood. Thus, predating the walled Jewish quarter and Ghettos, the Jews defined their habitats in the town as a close (although not yet an exclusive) Jewish space, and created a city within a city: a Jewish one within the Christian one. This phenomenon corresponds to the rise of the “community” as the boundary line of Jewish identity.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
