“Useful Knowledge” in Charles-Alexandre Lesueur’s visual and textual accounts of Missouri in 1826
Bibliographic record
Abstract
Artist and naturalist Charles-Alexandre Lesueur (1778-1846) valued his work as useful to science generally and to France in particular, including during the time he lived and traveled in North America from 1816 to 1837. Starting with Daniela Bleichmar’s concept of “visual epistemology: a way of knowing based on visuality, encompassing both observation and representation,” this essay claims that Lesueur’s art and scientific practice adhered closely to a belief in the authority of art from direct observation in nature, and they served different professional, educational, community, and potentially commercial purposes. It charts the conditions under which he produced the art, the purpose(s) of the art, the types of art (sketches, paintings, prints, landscape drawings), and the intended audience through four types of subjects from the expedition to Missouri in 1826: the challenges of scientific fieldwork, Blacks in Missouri, lead mining, and inland but especially riverside towns.

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.
