This glass is a rare example of an anti-Jacobite glass. The inscription on the glass, ‘The Ever Glorious Memory’, refers to King William III. He defeated James II at the Battle of the Boyne in Ireland on 1 July 1690, ensuring continued Protestant rule, or the Protestant Ascendancy, in the majority Catholic Ireland. Protestant Irish ‘Orange’ lodges drank toasts to the memory of King William in much the same way as the Jacobites toasted the Stuart monarchs.
