Thou, O Spirit

And chiefly Thou O Spirit, that dost prefer
Before all Temples th’ upright heart and pure,
Instruct me, for Thou know’st; Thou from the first
Wast present, and with mighty wings outspread
Dove-like satst brooding on the vast Abyss
And mad’st it pregnant: What in me is dark
Illumine

—John Milton, Paradise Lost (1667), 1.17-23.
