Excerpt from The Corpus Hermitic? 2. All things being undefined and yet unwrought, the light things were assigned unto the height, the heavy ones had their foundations laid down underneath the moist part of Dry Space, the universal things being bounded off by Fire and hanged in Breath to keep them up.
And Heaven was seen in seven circles; its Gods were visible in forms of stars with all their signs; while Nature had her members made articulate together with the Gods in her. And [Heaven's] periphery revolved in cyclic course, borne on by Breath of God.

Excerpt from Paradiso -- Canto XXVIII
The Angelic Orders
Perhaps as close a halo seems to circle
The starlight radiance that paints it there
Around the thickest mists surrounding it,

25 As close a ring of fire spun about
The Point so fast that it would have outstripped
The motion orbiting the world most swiftly.

And this sphere was encircled by another,
That by a third, and the third by a fourth,
30 The fourth by a fifth, the fifth then by a sixth.

The seventh followed, by now spread so wide
That the whole arc of Juno’s messenger
Would be too narrow to encompass it.
