This group gathers the spirits ranked as Kings among the seventy-two demons of the Ars Goetia, the first part of the Lesser Key of Solomon, a seventeenth-century grimoire that catalogues the spirits said to have been bound by King Solomon. The spirits are given noble and military ranks (king, duke, prince, marquis, earl, president, knight), modelled on an earthly court.
The browser will find the spirits of kingly rank. The atlas presents the Goetia as a historical textual tradition, describing each spirit's attributes and seal as the grimoire gives them, without endorsing the practice of conjuration.
