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.
-- John Milton (1608-1674)
-- Paradise Lost, Book ii, Line 666
