Ucanal Stela 29 and the Cosmopolitanism of Terminal Classic Maya Stone Monuments
Bibliographic record
Abstract
The Terminal Classic period (ca. AD 800–1000) in the Southern Maya Lowlands witnessed a precipitous decline in the erection of carved stone monuments, a decline that corresponds to shifts in political ideologies and the disappearance of many prominent royal dynasties. Although Southern Lowland sites are often considered peripheral to the events and innovations occurring elsewhere in Mesoamerica during this time, a recently discovered stela, Stela 29, at the site of Ucanal in Peten, Guatemala, underscores the active role of the site in broader political movements in the ninth century. Our iconographic, textual, and stylistic analysis of this stela, in concert with other Terminal Classic monuments from the site, reveals a vernacular cosmopolitan aesthetic whereby local Classic Maya styles were infused with images and elements that referenced connections with peoples from northern Yucatan, the Gulf Coast, and Central Mexico.

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.
