The Making of the Historic Heraldic Window for St. Paul’s Cathedral, London (Ontario): Christopher Wallis, Stained Glass, and the Heraldic Arts
Bibliographic record
Abstract
This paper explores the stained glass art of Christopher Wallis (1930–2021) through the Historic Heraldic Window he created for St. Paul’s Cathedral in London, Ontario. The window, created in 1990, celebrates the cathedral being granted heraldic arms on 28 May 1989, by the newly created Canadian Heraldic Authority (1988); the arms were the first granted to a religious institution in Canada by the fledgling government agency. By this time, Wallis had established himself as a leading heraldic glass artist, both domestically and internationally. For St. Paul’s, he designed and created a large heraldic window for the cathedral’s west transom entrance window. This paper analyzes original contracts to explore the window’s creation, imagery, and overall appearance in St. Paul’s west transom.

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.
