"The other shape,
If shape it might be call'd, that shape had none,
Distinguishable in member, joint, or limb;
Or substance might be call'd that shadow seem'd;
For each seem'd either; black it stood as night,
Fierce as ten furies, terrible as Hell,
And shook a dreadful dart; what seem'd his head
The likeness of a kingly crown had on.
Satan was now at hand; and from his seat
The monster, moving onward, came as fast
With horrid strides; Hell trembled as he strode."
-- John Milton
