The Seal of Methratton and the Explanation
Eheia, the name of the Divine Essence. His idea is called Kether, signifies a Crown or Diadem, hath his influence by the Order of Seraphim, or as the Hebrews call them Hayioth Hacadesh, i.e. Creatures of Holiness, and then by the Primum Mobile, whose particular Intelligence is called Methratton, that is the Prince of Faces, whose duty it is to bring others to the face of the Prince. And by him the Lord spake to Moses.
