Seal of Saturn
The Seal of Saturn is a magical symbol representing the intelligence of the planet Saturn. The magical tradition of using seals or signatures for spiritual energies or entities is quite old. Similar seals can be found on two thousand year old Coptic magical papyri; which is the latest written stage of the Egyptian language.
This particular example probably dates to medieval times, and is drawn from the “magic square” of Saturn, an ancient table of numbers believed to contain the magical essence of the planet. The magic square of Saturn is a table of the numbers one through nine, arranged in such a way that all rows add to 15. The seal is created by tracing the numbers in the square in order.
