In the Western Occult Tradition, each planet has traditionally possessed both a spirit and an intelligence: ethereal souls (sometimes called daemons) responsible for the baleful and beneficial influences (respectively) of the individual planet. After all, even humans have souls, and the planets of the Celestial realm are far more spiritual, existing closer to God and constructed of a much more rarefied matter. It was therefore logical to occultists that the planets also possessed their own souls.
Identity of the Intelligence
The name of Saturn's intelligence, responsible for the planet's beneficial influences, is Agiel.Construction of the Planetary Sigil
This sigil, published by Henry Cornelius Agrippa in his Three Books of Occult Philosophy and frequently repeated in other publications, is constructed through numerology and magic squares. The name Agiel is spelled out in Hebrew, and then each Hebrew letter is associated with a number, as the Hebrew language inherently does. Each number is located on the magic square associated with Saturn, and a line is drawn to pass through each number.Aesthetic Choices
The terminating circles at each end of the line appear to have been added for purely aesthetic reasons. Many hold that the sigil can also be freely rotated, either for aesthetic purposes or to further disguise the meaning and method of construction of the sigil.Purpose of The Sigil
This sigil would be used to attract the beneficial influences of Saturn, which according to Agrippa includes the ability to bring forth, to make a man safe, to make a man powerful, and to cause success of petitions with princes and powers. Marsilio Ficino and others also associated Saturn with intellectuals, whose minds are more lofty and divine than those of common folk. This is because Saturn is the highest planet in occult cosmology and therefore closest to God.Read more: More Correspondences of Saturn
