A Fifteenth-Century Plan of the Cathedral of Seville
Bibliographic record
Abstract
This article focuses on a recently identified and hitherto unpublished drawing of Seville Cathedral, recently located in the Bidaurreta convent (and thus described in this article as the ‘Bidaurreta drawing’). This document is of international importance as it constitutes a rare example of a medieval drawing of a Gothic cathedral, and is indeed the oldest known complete ground plan of any Gothic cathedral. It is also the only plan preserved intact that depicts any fifteenth-century Gothic building in Castile. The drawing, which this article suggests dates from the third quarter of the fifteenth century, is a modified copy of a 1433 plan of Seville Cathedral. It records the building as it was in 1433 and some of the subsequent changes, undertaken as part of a building campaign that ultimately lasted until 1506, by means of which the cathedral took on its present form: 126.18 m in length, 82.6 m in width and 30.48 m high (Figs 1-2). This article traces the reconstruction work in detail by examining the original documentary sources, many not previously discussed in English, together with the evidence of the drawing itself.

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.
