Paradise Lost Book 03
Hail, holy Light, offspring of Heaven firstborn, 
Or of the Eternal coeternal 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. 
Or hear"st thou rather pure ethereal stream, 
Whose fountain who shall tell?  before the sun, 
Before the Heavens thou wert, and at the voice 
Of God, as with a mantle, didst invest  *** 
The rising world of waters dark and deep, 
Won from the void and formless infinite.
