An Historical Summary of Angelic Hierarchies from Part VII: The “Seven” Thrones in In Operibus Sigillo Dei Aemeth by David Richard Jones.

“These Thrones, who are assigned to govern this heaven, are not great in number, though the philosophers and the astrologers have estimated it diversely according to how diversely they have estimated its rotations, although all are agreed on this point: that there are as many of them as there are movements made by the heaven.” [via]
