Each planet has its own seal or signature, as well as the signature of
its intelligence and the signature of its demon. These signatures were
supposed to represent the characters of the planets' intelligences and
demons respectively. The signature of Mars is shown in fig. 26, that of
its intelligence in fig. 27, and that of its demon in fig. 28.

These various details were inscribed on the talismans each of which
was supposed to confer its own peculiar benefits--as follows:
On one side must be engraved the proper magic table and the astrological
sign of the planet, together with the highest planetary number,
the sacred names corresponding to the planet, and the name of
the intelligence of the planet, but not the name of its demon.
On the other side must be engraved the seals of the planet
and of its intelligence, and also the astrological sign.
BARRETT says, regarding the demons:[1] "It is to be understood
that the intelligences are the presiding good angels that are set
over the planets; but that the spirits or daemons, with their names,
seals, or characters, are never inscribed upon any Talisman,
except to execute any evil effect, and that they are subject
to the intelligences, or good spirits; and again, when the spirits
and their characters are used, it will be more conducive to the effect
to add some divine name appropriate to that effect which we desire."
Evil talismans can also be prepared, we are informed, by using a metal
antagonistic to the signs engraved thereon. The complete talisman of
Mars is shown in fig. 29.
