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

“The last important source for understanding the Thrones and the Dionysian hierarchies before the discovery of the Hermetica is Dante (c. 1265–1321). The Dionysian order is central to the structure of the Paradiso of Dante’s Divine Commedy and therefore the Thrones must be encountered on the celestial ascent.

Above are mirrors, Thrones you call them,
from which shines to us God the adjudicator
thus we ensure that it is right to say all these things

Here she was silent, and she appeared
to turn toward other things, reentering, onto the wheel
and again into the dance.
Dante, Paradiso Canto 9″ [via]
