'His spirit is their power, and they his slaves
In air, and light, and thought, and language, dwell;
And keep their state from palaces to graves, _390
In all resorts of men--invisible,
But when, in ebon mirror, Nightmare fell
To tyrant or impostor bids them rise,
Black winged demon forms--whom, from the hell,
His reign and dwelling beneath nether skies, _395
He loosens to their dark and blasting ministries.

'In the world's youth his empire was as firm
As its foundations...Soon the Spirit of Good,
Though in the likeness of a loathsome worm,
Sprang from the billows of the formless flood, _400
Which shrank and fled; and with that Fiend of blood
Renewed the doubtful war...Thrones then first shook,
And earth's immense and trampled multitude
In hope on their own powers began to look,
And Fear, the demon pale, his sanguine shrine forsook. _405

'Then Greece arose, and to its bards and sages,
In dream, the golden-pinioned Genii came,
Even where they slept amid the night of ages,
Steeping their hearts in the divinest flame
Which thy breath kindled, Power of holiest name! _410
And oft in cycles since, when darkness gave
New weapons to thy foe, their sunlike fame
