Hierarchies Recapitulated from Part VII: The “Seven” Thrones in In Operibus Sigillo Dei Aemeth by David Richard Jones.

“Further, this correspondence would identify the Thrones with the names drawn from the Circumference and the seven Seals, the Archangels drawn from the Septagon would be the Trumpets and the planetary Angels about the pentagram would be the Angels. Compare Part I of this series where these divisions are laid out in detail.” [via, see]
