The Sigillum Dei (seal of God, or signum dei vivi, symbol of the living God, called by John Dee the Sigillum Dei Aemaeth, or Seal of the Truth of God. “Ameth” is Hebrew for “truth.” ) most widely known through the writings and artifacts of John Dee, a 16th century occultist and astrologer in the court of Elizabeth I. Was a late Middle Ages magical diagram, composed of two circles, a pentagram, and three heptagons, and is labeled with the name of God and his angels. It was an amulet (amuletum) with the magical function that, according to one of the oldest sources (Liber iuratus), allowed the initiated magician to have power over all creatures except Archangels, but usually only reserved for those who can achieve the blessed vision of God and angels (beatific visionary).
Dee’s system of angelic magic, known as Enochian, is heavily rooted in the number seven, a number which is also strongly connected with the seven traditional planets of astrology.
The Outer ring contains the names of seven angels, each associated with a planet. To find a name, start with a capitalized letter on the ring. If there is a number over it, count that many letters clockwise. If there is a number under it, count that many letters counterclockwise. Continuing the procedure will spell out the names:
These are the Angels of Brightness, who comprehend the seven “inward powers of God, known to none but himself.”
Inside the outer ring are seven symbols based on the letters forming “Galethog,” with “th” being represented by a single sigil. The name can be read counter-clockwise. These seven sigils are the “Seats of the One and everlasting GOD. His 7 secret Angels proceeding from every letter and cross so formed: referring in substance to the FATHER: in form, to the SON: and inwardly to the HOLY GHOST.”
The names of the “Seven Angels who stand before the presence of God,” each also associated with a planet, were written vertically into a 7-by-7 grid. By reading the grid horizontally, you get the seven names listed in the outer heptagon. The seven original names were:
The resulting new names are written clockwise.
The next five levels are all based off of another 7-by-7 grid of letters. Each is read in a different direction. The letters are names of more planetary spirits, originally written in a zigzag pattern, starting in the upper left corner (the “el” of each name was removed in the creation of the grid):
The names between the outer heptagon and heptagram are constructed by reading the grid horizontally. They are the “Names of God, not known to the Angels; neither can be spoken nor read of man.”
The names within the points of the heptagram are the Daughters of Light. The names within lines of the heptagram are the Sons of Light. The names within the two central heptagons are the Daughters of the Daughters and the Sons of the Sons.
The planetary spirits are repeated around the pentagram. The letters spelling out Sabathiel (with the final “el” again removed) are scattered around the outside. The next five spirits are spelled out closer to the center, with the first letter of each name within a point of the pentagram. Levanael is at the very center, surrounding a cross, a common symbol of earth.
