870
Thus saying, from her side the fatal Key,
Sad instrument of all our woe, she took;
And towards the Gate rouling her bestial train,
          the huge Portcullis high up drew,
Which but her self not all the Stygian powers
Could once have mov'd; then in the key-hole turns
Th' intricate wards, and every Bolt and Bar
Of massie Iron or sollid Rock with ease
Unfast'ns: on a sudden op'n flie
With impetuous recoile and jarring sound 880
Th' infernal dores, and on thir hinges great
Harsh Thunder, that the lowest bottom shook
Of Erebus.
