Hail holy Light, offspring of Heav'n first-born. Bright effluence of bright essence increate.john milton: 1665 Paradise Lost (published1667), bk.3, l.5-6.
And yet the doing is ours, not His. He inspired it, we wrought it out. He quickened, but we brought forth. His the heart-beat, but ours the hand-stroke; His the influence, ours the effluence.george c. lorimer: P. 125. (Dictionary of Burning Words of Brilliant Writers (1895))
Hail, holy light! offspring of heaven firstborn! Or of th' eternal co-eternal beam, May I express thee unblam'd? since God is light And never but in unapproached light Dwelt from eternity, dwelt then in thee, Bright effluence of bright essence increate!John Milton, Paradise Lost (1667; 1674), Bk III, line 1.
