And if it be Prometheus stole from Heaven
The fire which we endure[530]--it was repaid
By him to whom the energy was given
Which this poetic marble hath arrayed
With an eternal Glory--which, if made
By human hands, is not of human thought--
And Time himself hath hallowed it, nor laid
One ringlet in the dust--nor hath it caught
A tinge of years, but           the flame with which 'twas wrought.
