How does Milton create the elevated, epic style that gives Paradise Lost its power?

Milton's Paradise Lost's epic style
results from several techniques:

(1) Milton uses an
unconventional syntax and lengthy sentences, making his lines difficult to read.  But in
so doing, he engages the reader in the text.

(2) Biblical
and classical allusions that lend formality to the
lines.

(3) Powerful lines that are easy to remember because
of their alliteration, assonance, and parallel
structure:

"Better to reign in Hell than serve in
Heaven."

or

"The mind is its
own place, and in itself

Can make a Heaven of Hell or a
Hell of Heaven."

(4) The
creation of such a fascinating character as Satan, who in his pride and unconquerable
will, provides a riveting antagonist:

"What though the field be
lost?

All is not lost; the unconquerable
will,

And study of revenge, immortal
hate,

And courage never to submit or
yield:

And what is else not to be
overcome?"

(5) Imagery that
creates indelible impressions on the reader:

Him the Almighty
Power

Hurled headlong flaming from the ethereal
sky

With hideous ruin and combustion
down

To bottomless perdition . .
