A Cosmographia de Claudius Ptolomaeus:um manancial de conhecimentos doado pelo imperador D. Pedro II à Biblioteca Nacional
Bibliographic record
Abstract
The Geographia, by Claudius Ptolomaeus, an amount of knowledge donated by the emperor D. Pedro II to the National Library, constitutes a multiple work of a peculiar feature: the text is almost totally composed of toponyms (8.000) but the ideas expressed are so important that although being written in the II Century B. C., thus near the turn of the century (1472-1475), it is republished in Latin, considered the language of culture at that moment. Two aspects were chosen to be studied here: 1. The life of the work since its first publication, up to the beginning of the Middle Ages, its survival supported by the innovating ideas in the elaboration of maps, which are the source of great questionings about the geographic space in the period of the great discoveries. Written in Alexandria, in Roman Egypt, the Geographia called the Arab’s attention, in the IX Century, and in the beginning of the XV (1406), translated into Latin, it is presented in Europe as codex manuscript. In this century a number of handwritten copies were made and they are still preserved. In the last quarter of the century (1472/1475) the first editions in closed version were published, all in Latin. 2. Linguistic commentaries and analysis of the characteristics of the 1486 edition, of the collection of Empress Thereza Christina Maria, donated by the emperor D. Pedro II to the National 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.
