Andreas Libavius and the Transformation of Alchemy: Separating Chemical Cultures with Polemical Fire
Bibliographic record
Abstract
Andreas Libavius (or Liebau, ca 1550--1616) was an enormously learned, prolific and, in his day, respected writer whose supposedly pivotal role in the history of chymistry has been asserted a good deal more often than it has been analyzed. 1 Having studied philosophy, history, and medicine at Wittenberg and Jena, Libavius became a city physician and school inspector at Rotenburg ob der Tauber for a time, and gained something of a reputation for his Latin poetry. Most of his career, however, was spent as teacher or headmaster at assorted secondary schools, inculcating logic and rhetoric into teenage boys. The interests that he pursued in his spare time were encyclopedic, encompassing theology, philosophy, literature, logic, and medicine; but his primary concern and the subject of by far the greatest number of his published works-works dryly described by Hugh Trevor-Roper as being 'of Teutonic length, depth and weight ' [2006, 86]-was the tantalizingly ill-defined topic that Libavius himself generally referred to as 'alchemy'.

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.
