Abstract
As Europeans ventured more frequently on transoceanic voyages in the 16th century, it became essential for navigators to be able to carry out mathematical computations. Iberian educators rose to the occasion, developing textbooks and curricula to transmit these abstract concepts. At the same time that they strove to present new mathematical techniques, these maritime authors also captured the tacit skills that had been practiced for centuries. Thus, even though few working sailors put pen to paper, it is possible to recover aspects of their epistemology from these texts. Because books traveled so easily across borders, these academic sources also had far-reaching effects, inspiring similar educational programs across maritime Europe. This article recommends adopting a comparative perspective, since much can be learned by tracing the evolution of these shared practices as they traveled from Spain and Portugal to the Netherlands, France, and England, and back again.

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.
