This talisman combines the Third and Fourth Pentacle of Mercury from the Greater Key of Solomon. It's written that it's influences correspond to “invoking all spirits subject to Mercury” for the purposes of “finding hidden treasure, enchancing artistic and scientific ability, increasing psychic communication, convey personal magnetism, and open the door to secret knowledge.”
These seals were lifted from the “Greater Key of Solomon”, a foundational grimoire of Western Esotericism that contains influences of Judaic mysticism/Kabbalah, Roman astrology and Hermetic alchemy.
“Every one knoweth in the present day that from time immemorial Solomon possessed knowledge inspired by the wise teachings of an angel, to which he appeared so submissive and obedient, that in addition to the gift of wisdom, which he demanded, he obtained with profusion all the other virtues; which happened in order that knowledge worthy of eternal preservation might not be buried with his body.” [The Greater Key of Solomon (1999), Liddell & Mathers]
