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

“According to the best demonstration of the astrologers as we find it summarized in the book of the Constellations of the Stars, these movements are three: one according to which the star moves along its epicycle; a second according to which the epicycle moves together with the whole heaven in concert with that of the Sun; a third according to which that whole heaven moves, following the movement of the starry sphere, from west to east, one degree every one hundred years.” [via]
