Ars Quatuor Coronatorum
The Transactions of Quatuor Coronati Lodge No. 2076
Quatuor Coronati Lodge No. 2076, consecrated in 1884 under the United Grand Lodge of England, is the world's first and foremost lodge of Masonic research. Its founding members — among them Sir Charles Warren, William Simpson, and Robert Freke Gould — established a new discipline: the rigorous historical and archaeological study of Freemasonry, free from the romantic mythologizing that had long characterized the Craft's self-understanding.
The Lodge's journal, Ars Quatuor Coronatorum (AQC), has been published annually since 1888. Its papers — delivered before the Lodge and published with formal discussion by respondent brethren — represent the most sustained body of Masonic scholarship in existence. Contributors have included historians, orientalists, archaeologists, and antiquaries of the first rank.
Through its “Correspondence Circle,” QC Lodge extended membership far beyond the nine chair-holding brethren, creating an international network of researchers whose contributions appear throughout these volumes. The result is a unique archive: serious historical scholarship produced from within the institution it studies.

Source & method
All volumes are public domain, sourced from Internet Archive digitizations of originals held by university libraries (primarily Brigham Young University and the University of Toronto). Original scans are typically 400–600 dpi; these were downsampled to 300 dpi and split into 15-page chunks for processing.
Transcription is performed by vision-language model — the AI reads the actual page images (no traditional OCR engine is involved) and produces structured markdown preserving the original layout, footnotes, tables, and typographic conventions.
A small number of pages across several volumes are unavailable due to content safety filters in the transcription pipeline. These gaps are noted in each volume's entry above.
