The three Divine are in this hierarchy, First the Dominions, and the Virtues next;
And the third order is that of the Powers. The in the dances twain penultimate
The Principalities and Archangels wheel; The last is wholly of angelic sports.
These orders upward all of them are gazing,
And downward so prevail, that unto God
They all attracted are and all attract.

The Divine Comedy of Dante Alighieri (ed. 1867)
