The bizarre, satiric reunion of Satan with his daughter, Sin, and their offspring, Death, a parody of the Trinity, among other things. The shift of style to allegory for satiric purposes. Satan’s journey through Chaos on his way to earth. Chaos as “the deep” of Genesis 1, but also the Chaos of the Creation myths of Hesiod, Ovid, and Lucretius. The surreal picture of an undignified Satan having to fly, creep, swim, as Chaos turns moment by moment from solid to liquid to gas. The moving personal invocation to God as an inward light at the opening of Book 3, compensating for the painful solitude of Milton’s blindness. One of the most beautiful parts of the poem.
