We have had a photocopy of a 300 year old magical manuscript in our archives for fifty years and have used it or research, study, rituals, and publications but until we began a serious study of Valentinian Gnosticism we had no idea what secrets were hidden in this Elizabethan era manuscript that we had been using for years. The structure of the Celestial and Terrestrial versions of the Tetragrammaton was set forth in the First Conjuration of the Goetia. Elizabethan magicians were NeoPlatonists and Hermetics. They were partial to Christian Gnosticism and venerated the most high God, honoring Jehovah as the God of the Earth Sphere. I now wonder if Sloane 2731 influenced us to realize the two Tetragrammatons years before we discovered them in the text of the First Conjuration.
