The Good-Night

Now, as in Tullia's tomb one lamp burnt clear 
Unchanged for fifteen hundred year, 
May these love-lamps we here enshrine, 
In warmth, light, lasting, equal the divine. 
Fire ever doth aspire, 
And makes all like itself, turns all to fire, 
But ends in ashes; which these cannot do, 
For none of these is fuel, but fire too. 
This is joy's bonfire, then, where love's strong arts 
Make of so noble individual parts 
One fire of four inflaming eyes, and of two loving hearts.

— John Donne, "XI: The Good-Night," from "Eclogue: at the Marriage of the Earl of Somerset" (see Busman's Honeymoon)
