Nicholaus de Heybech of Erfurt, Table Maker and Copyist
Bibliographic record
Abstract
Nicholaus de Heybech (fl. 1384–1394) is the author of a clever and compact solution to a major challenge for medieval astronomers: finding the time from mean to true syzygy. His table and associated canon for that purpose are now found in 30 manuscript copies, which means that this table was one of the most widely diffused single tables in Alfonsine astronomy. In this article, we present two different and hitherto unnoticed tables by Nicholaus de Heybech for determining mean syzygy, which nicely complement the table that is already known, and we gather the information available on another aspect of his activity beyond table making, as a copyist of texts and tables mainly in mathematical astronomy.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
