Bibliographic record
Abstract
This thesis presents an interdisciplinary approach to a 12th century illuminated manuscript, a Leccionarium (Alc. 433), produced in Alcobaça Monastery which currently is being preserved at Biblioteca Nacional de Portugal in Lisbon. The aim of the work was to trace the biography of this illuminated manuscript, through the liturgical studies and to obtain the chronological timeline of the use of materials in Alcobaça scriptorium, through centuries. The representative folia of Alc. 433 were characterised with h-XRF, UV-Vis-NIR-FORS, and hyperspectral images. The result indicates that Alc. 433 was produced in the last quarter of the 12th century, followed by addition of some folia in 13th, 14th, and the beginning of 17th century. Materials identification revealed the use of different pigments in different periods: vermilion and minium (red), copper proteinate (bottle green), yellow lake pigments, azurite and lapis lazuli (blue). The PCA study of yellow lake dye reproduction indicates the use of turmeric yellow lake pigment in the initial core. Furthermore, the analysis of iron gall ink also shows that the initial core of Alc. 433 contains the similar ratios of elements with Alc. 11 (primitive manuscript of Alcobaça) thus proved the Alc. 433 was also the produced in the earliest period of the active year of Alcobaça scriptorium; RESUMO: O Estudo da Trajetória Biográfica do Manuscrito Português Iluminado do Século XII: Leccionarium Alc. 433 da Coleção de Alcobaça Detida pela Biblioteca Nacional de Portugal Esta tese apresenta uma abordagem interdisciplinar de um manuscrito iluminado do século XII, um Leccionarium (Alc. 433), produzido no Mosteiro de Alcobaça e que se encontra preservado na Biblioteca Nacional de Portugal em Lisboa. O objetivo deste trabalho foi traçar a biografia deste manuscrito iluminado, através do seu estudo litúrgico e obter a linha cronológica da utilização de materiais no scriptorium de Alcobaça, ao longo dos séculos. Os fólios mais representativos do Alc. 433 foram caracterizados h-XRF, UV-Vis-NIR-FORS e imagens hiperespectrais. O resultado indica que o Alc. 433 foi produzido no último quarto do século XII, e que foi enriquecido com a adição de fólios e/ou cadernos nos séculos XIII, XIV e inícios do século XVII. A identificação dos materiais revelou o uso de diferentes pigmentos em diferentes períodos: vermelhão e minium (vermelho), proteinato de cobre (verde garrafa), pigmento lago amarelo, azurite e lápis-lazúli (azul). O estudo PCA da reprodução do corante lago amarelo indica o uso de açafrão no núcleo inicial do pigmento. Além disso, a análise das tintas de escrita evidenciou uma analogia de composição da tinta ferrogálica utilizada no núcleo inicial do manuscrito Alc.433 e da tinta ferrogálica utilizada no texto do Alc.11 (outro manuscrito produzido nos primeiros anos do scriptorium de Alcobaça) o que comprovou assim que também o Alc. 433 foi produzido na mesma época, isto é, em torno de 1175.

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.
