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

“Dee would certainly have known of the famous first translation into Latin by the Neoplatonist and suspected heretic, Johannes Scotus Erigena/Eriugena, (c. 815–877), but it seems unlikely that he was aware of Eriugena’s rather controversial commentaries. These commentaries were not rediscovered until 1681 along with the condemned De division nature.” [via]
