The moon (?) as a six-pointed star (of David) with 16 ‘blazing flames’. There appears to be something in the middle too.
Cooper writes: “The first image (top left) is suggestive of the universe with the Trinity (three triangles) at its centre.”
In his essay about The Harodim in Acta Macionica Volume 25 (6018), Jan Snoek presents the title page of the constitutions of the Grande Loge d’Angleterre Parfaite Observance no.1″ (1783) which has the ‘star of David’ with a triangle in the middle. The title page has some other interesting symbols, but not in the context of this website (I think).
Also the Grand Chapter of London appears to have had a ‘star of David’ with a triangle in the middle in their seal from 1769 (!) to 1817. See here (accessed 1 March 2024)
