“The study of the biographical trajectory of a Portuguese 12th c. illuminated manuscript: the Leccionarium Alc. 433 from Alcobaça collection held by the Biblioteca Nacional de Portugal”
Bibliographic record
Abstract
Medieval illuminated manuscripts are among the best testimonies of the life of medieval scriptoria. This work traces the biographical trajectory of a Lectionary according to the Cistercian rite – the Alc. 433 - through the liturgical studies and the material characterisation of its painted illuminations, with the aim of obtaining the chronological timeline of the use of colour materials in the Portuguese scriptorium of Alcobaça. For this, liturgical analysis of the manuscript combined with the material characterisation of a selection of representative folia of Alc. 433 with non-invasive in- situ analysis (h-EDXRF, UV-Vis-NIR-FORS, and hyperspectral imaging analysis) was used. The result indicates that it was produced in the last quarter of the 12th century, followed by the addition of some folia in the 13th, 14th, and the beginning of the 17th century. Materials identification revealed the use of the most common inorganic pigments for this period. As for organic colour materials, turmeric was identified as a yellow lake pigment.

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.
