The following material is a 24 September correction
from my 23 September posting. For I discovered -- in a thoughtful email from Ghrist --
that the proper citation of "space" was not from line 50 of Book 1 but from line 89 of Book 7.
(I invite you go to Project Gutenberg for Paradise Lost in its entirety.)
Here, below, I have replaced my original posting of lines 44-74 of Book 1
with lines 80 - 97 of Book 7 -- lines taken from my shelf copy of Milton's Paradise Lost,
the 1968 Signet Classic Edition, edited by Christopher Ricks.
In the selection below and throughout his epic, Milton replaces past visions of hell down-in-the-earth and heaven up-in-the-sky with more complex and abstract configurations.
