Abstract

fetched live from OpenAlex

The present book is a highly technical study in which the authors describe and analyze the astronomical texts of Abraham Zacut , an outstanding intellectual figure in the Spanish Jewish community who lived, as the title indicates, in a very interesting period: the transition from manuscript to print. Zacut benefited from contact with Christian astronomers in Salamanca who had access to a vast corpus produced by astronomers from all over northern Europe. He also took advantage of the Jewish tradition in astronomy that developed mainly in southern France and Spain during the late Middle Ages. When the Jews were expelled from Spain in 1492, he moved to Portugal where he remained until 1496. Later, in Tunis, he made an adaptation of one of his works, the H . ibbur, for the year 1501 and prepared, around 1513, a new set of tables for Jerusalem using the Jewish calendar.

Not 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.
