A Commentary on the Categories from the School of Alberic in Padua, Biblioteca Universitaria 2087: An analysis of the manuscript
Bibliographic record
Abstract
This article examines Padua, Biblioteca Universitaria 2087, the only known manuscript preserving the anonymous twelfth-century commentary on Aristotle’s Categories known as C15, traditionally linked to the School of Alberic. While C15 has been studied for its logical content, the manuscript itself has received little attention. Through a codicological and palaeographical analysis, this study reconstructs the material history, structure, and context of production of the codex. The manuscript is shown to be largely a palimpsest, copied on reused parchment possibly originating from an earlier grammatical handbook, including fragments of Eutyches’ De verbo. Analysis of the ruling, mise en texte, and scripts – three hands in a transitional Caroline minuscule –supports a dating to the second or third quarter of the twelfth century and suggests a North-Western European school context. The material features of the codex confirm its origin as a study manuscript produced within a medieval educational environment closely linking grammatical and logical teaching.

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.
