Paradise Lost

I'm on book 4, around line 160. I'm kind of enjoying it. I like the writing style but I am having trouble following the action. For example:

164: Well pleased they slack their course, and many a league
165: Cheered with the grateful smell old Ocean smiles.
166: So entertained those odorous sweets the Fiend
167: Who came their bane, through with them better pleased
168: Than Asmodeus with the fishy fume,
169: That drove him, though enamoured, from the spouse
170: Of Tobit's sone, and with a vengeance sent
171: From Media post to Egypt there fast bound.

Satan's enjoying the smells of Eden. Milton compares this experience to some other literary/historical characters I am not familiar with - Asmodeus, Tobit, Media (is that a character?). That said, the scene seems interesting. Satan was reminded of how things were when he was an angel. He was taken by how lovely Eden was. He thought about going back and asking for forgiveness. Good stuff.

Anyway, I'm hoping to make it through this whole thing even though the writing is half opaque.
