Abstract

fetched live from OpenAlex

L’étude de laboratoire des autoportraits présumés de Goya conservés dans les musées d’Agen, Castres et Bayonne permet de préciser leur attribution. Le tableau d’Agen, dont l’attribution et la datation ont été discutées, présente en radiographie des détails caractéristiques d’un autoportrait peint devant un miroir ; il a vraisemblablement été peint vers 1783 afin de préparer l’insertion du portrait du modèle dans la Prédication de saint Bernardin de Sienne de l’église San Francisco el Grande de Madrid. Le Portrait de l’artiste conservé au musée de Castres n’a pas les caractéristiques techniques d’un original de Goya ; il s’agit, selon l’auteur de ces lignes, d’une réplique non autographe réalisée dans l’entourage du maître. En revanche, l’étude de laboratoire et la restauration récente du tableau de Bayonne, souvent négligé, semblent indiquer qu’il s’agit d’une œuvre autographe préparant le portrait de l’artiste peint à l’arrière-plan de la Famille de Charles IV (Madrid, musée du Prado).

Not 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.
