The "Testament of Solomon," details King Solomon's supernatural authority over various demons, including the spirits of fallen giants. Through a magical ring given by an archangel, Solomon summons and interrogates these entities, compelling them to assist in building the Temple and revealing their names, origins, and weaknesses to specific angels. The narrative highlights the demons' malevolent influence on humanity and their eventual subjugation by Solomon, though it concludes with a prophecy of his kingdom's downfall due to his later idolatry and the demons' eventual re-emergence. The accompanying analysis further connects these events to the alleged discovery of Solomon's ring and the imprisoned spirits by the Knights Templar, linking them to the origins of secret societies.
