"Paradise Lost" has long proved popular with revolutionary thinkers.

On winter nights in the early sixteensixties, a blind poet lay awake in his bed and dreamed of the universe. Before his eyes swam suns and stars. A celestial light, visible to him alone, revealed a procession of images: first, a great battle in Heaven, between Satan's rebel angels and the armies of God, who chased the rebels into a new realm, Hell; next, God's creation of Earth and the inhabitants of Paradise, chief among them Adam and Eve; then a glimpse of Satan, who flew from Hell to tempt Eve to eat the fruit from the Tree of Knowledge; and, finally, man's exile from Paradise.

It may be an apocryphal story but feels true to the poem; it was as if God had filled the poet to the brim, until he had to be drained by the hands of mere mortals.
