The sun (?) as a blazing seven pointed star. In the middle there are three interlocked triangles that we also know from the sixth degree of the Ancient and Accepted Scottish Rite (“Intimate Secretary”). There the symbol also has a Hebrew-like character in each triangle. There seem to be no other references to (a predecessor of) that degree.
Cooper writes: “The image at the top right is indicative of the Sun and Moon (our planetary system) again with the Trinity at the centre and again represented by three triangles.”
