A chronological catalogue of stained glass commissions executed by Thomas Willement, listing dates and locations across Britain, describing designs—armorial windows, portraits, religious figures, ornamental borders, and restorations—placed in churches, colleges, private estates, and royal or civic buildings. Each entry notes patrons, heraldic devices, subjects copied from earlier works, and occasional presentations, with details of composition such as shields, crests, mosaic grounds, and altar or staircase placements. The account emphasizes craftsmanship and provenance by specifying commissions, donors, and where panels were installed or transferred.
