Abstract
Giovanni Mercati (1866-1957) fu uno dei protagonisti della storia della Biblioteca Vaticana nella prima metà del Novecento. La sua conoscenza con Ehrle risale al 1897; da allora e per quasi quarant’anni i due ecclesiastici collaborarono intensamente al programma di rinnovamento della biblioteca dei papi voluto da Leone XIII. L’analisi del rapporto fra i due – sotto il profilo umano, scientifico e istituzionale – si allarga a una considerazione della modernizzazione della Biblioteca Vaticana tra la fine dell’Ottocento e il primo quarantennio del XX secolo. Della prima fase, sotto il pontificato di Leone XIII (1878-1903), fu protagonista Ehrle; la seconda fase, sotto Pio XI (1922-1939), fu animata da Eugène Tisserant (1884-1972). Mercati attraversa i due momenti con un ruolo particolare. Con i tre personaggi (Ehrle, Mercati, Tisserant) si chiude comunque un’epoca e tramonta una concezione secolare della biblioteca papale. Giovanni Mercati (1866-1957) was one of the protagonists of the Vatican Library’s history during the first half of the twentieth century. Since his first acquaintance with Franz Ehrle in 1897, and for almost forty years, Mercati joined Ehrle’s efforts to renew the Popes’ library in accordance with a programme established by Leo XIII. Analysing the relationship between Mercati and Ehrle, from a human, scientific and institutional point of view, enables a survey of the modernisation of the Vatican Library from the end of the nineteenth century through the 1940s. Ehrle was the protagonist of a first phase, coinciding with Leo XIII’s pontificate (1878-1903); Eugène Tisserant (1884-1972) was the driving force of a second phase, under Pius XI (1922-1939), whilst Mercati played a key role during both phases. Ehrle, Mercati and Tisserant marked a time which saw the waning of a time-honoured concept of the papal library.

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.
