Paradise of fools

In Vallombrosa, where th' Etrurian shades

High overarch't imbowr; or scatterd sedge

Afloat, when with fierce Winds Orion arm'd

Hath vext the Red-Sea Coast, whose waves orethrew

Busiris and his Memphian Chivalry,

While with perfidious hatred they pursu'd

The Sojourners of Goshen, who beheld

From the safe shore thir floating Carkases

The links offer explanations.  
An Italianate illusion of leaves and wind, flows into reminiscing on the reforming of  the red sea over dead Egyptians.

From Aroar to Nebo, and the wild

Of Southmost Abarim; in Hesebon

And Heronaim, Seons Realm, beyond

The flowry Dale of Sibma clad with Vines,

And Eleale to th' Asphaltick Pool.

’Twas brillig, and the slithy toves

      Did gyre and gimble in the wabe:

All mimsy were the borogoves,

      And the mome raths outgrabe.

Hmm....  study your old Testament and your classics to pull this one apart.  It reminds me of how Shakespeare mixes biblical and classical references together as if they were from the same source (with a touch of Lewis Carroll perhaps).

The rhythm and texture are evocative of Frankenstein. I enjoyed hearing that the monster picks up the discarded knapsack of Frankenstein and finds a book of Milton's Paradise Lost, and Petrarch, and Goethe.  From this he learns to read.  I am guessing that Mary Shelley, in her teens, was impressed by the importance of these books (important books).  They are her books that resonate.

Great quotes:

The mind is its own place, and in it self

Can make a Heav'n of Hell, a Hell of Heav'n.

Better to reign in Hell, then serve in Heav'n.

Both glorying to have scap't the Stygian flood

As Gods, and by thir own recover'd strength,

Satan and the fallen angel travel to Hell over the river Styxs.  An example of the mixing of biblical and classical mythology.

I am inspired by this essay by Wm Moeck.  The Monster reads Milton: Paradise Lost
