As you can see, Ravignat calls this “The Jewel of a Sovereign Prince of the 87th” of Memphis Misraim. The counting of his reconstructed Traditional Egyptian Freemasonry differs from the counting in manuscripts he used. He gives no source for the image, but it appears to be from MS.-370 of the Fonds Gaborria, “Rite de Misraïm. Sup… Grand Cons… Gén… des Grands Ins… Intend… Rég… Généraux. 77e degré, 14e classe”, but there it is a signature of the 77th degree” .
In Ravignat’s ritual the image is described as: “a silver Half-Moon with three points surrounding a gold square with a point in the center”.
