The glory of the One Who moves all things
shines through the universe and is reflected
by all things in proportion to their merit.

[La gloria di colui che tutto move
per l’universo penetra, e risplende
in una parte più e meno altrove.]

Dante Alighieri (1265-1321) Italian poet

The Divine Comedy [Divina Commedia], Book 3 “Paradiso,” Canto 1, l. 1ff (1.1-3) (1320) [tr. Musa (1984)
    (Source)

God as the "unmoved mover" derives from Aristotle (Metaphysics 12.7), frequently referenced in medieval Scholastic writings.

Musa provides this variant translation as "a more interpretive rendering" in his notes (and a rendering similar to Ciardi's). His more literal translation, which he uses in the main text, is given below.

Launches thro' boundless space the stellar Band,
And shines effulgent, or involves his Throne
In darkness, as he wills ....
