In the Western occult tradition, each planet can be represented by a seal or diagram. The seal is based off of the planet's magic square, with the seal theoretically touching every number within the square, although in practice that is not always apparently the case.
The Seal of Jupiter follows the convention of overlapping every number of the magic square of Saturn. In addition, the seal's construction reflects the method of the square's construction. The diagonal lines intersect with numbers which were inverted in the first stage of the square's construction, similar to the seal of Jupiter.
The rest of the numbers are included via a symmetrical design. The use of curves instead of striaght lines may or may not reference the astrological symbol for the Sun. The circles in the four corners are most likely for aesthetic reasons, as appears to be the case with the other seals.
