Joseph ben Solomon Ṭaiṭaṣaq on the Construction of an Astrolabe: Study, Diplomatic Edition, and Annotated Translation
Bibliographic record
Abstract
This article presents the Hebrew edition and English translation of a treatise on the construction of an astrolabe composed by Joseph ben Solomon Ṭaiṭaṣaq in the last quarter of the fifteenth century, extant in a single manuscript never previously studied. This article ties the astrolabe described by Ṭaiṭaṣaq to a specific tradition of astrolabe construction, which is reflected in two components of the rete and is also witnessed in the Middle Ages in a single Latin/Catalan astrolabe preserved at the Museum of Fine Arts in Boston. Ṭaiṭaṣaq's instrument and the Catalan astrolabe share two remarkable and unique characteristics which may suggest a common literary source for their construction, a common astrolabe workshop, or a common craftsman tradition.

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.
