Illuminating Methods, Picturing Instruments: Tycho Brahe's Instrumental Images
Bibliographic record
Abstract
Abstract This article considers the function of twenty-two hand-colored prints of mathematical instruments in Tycho Brahe's Astronomiae instauratae mechanica (Instruments of the renewed astronomy; 1598), a hand-painted presentation treatise dedicated to Emperor Rudolf II and conferred on a network of individuals connected to the imperial court in Prague. Although the accompanying text communicates the instruments’ use and composition, the images demand close inspection because they articulate Brahe's observationally driven astronomy. They do so through structured, repeated, and consecutive representations; through expanded viewer access, achieved by adhering to multiple perspectives; through the juxtaposition of colors, which focuses attention on the heads of the instruments (the part that does the measuring); and through the use of gold paint, which emphasizes the head and brings to mind the very metallic nature of the instruments. Much like an astronomer taking multiple measurements of cosmological phenomena, these images allow viewers and readers, as they leaf through the pages of the treatise, to become virtual participants in Brahe's instauration of astronomy.

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.
