Murmur

The Fifty-fourth Spirit is called Murmur, or Murmus, or Murmux. He is a Great Duke, and an Earl; and appeareth in the Form of a Warrior riding upon a Gryphon, with a Ducal Crown upon his Head. There do go before him those his Ministers with great Trumpets sounding. His Office is to teach Philosophy perfectly, and to constrain Souls Deceased to come before the Exorcist to answer those questions which he may wish to put to them, if desired. He was partly of the Order of Thrones, and partly of that of Angels. He now ruleth 30 Legions of Spirits. And his Seal is this, etc.
