I've just caught up @ShackletonSailingSouth. Agree these were great chapters. I remember learning about Scylla and Charybdis at school and wanting to run a nightclub called Charybdis!
Poor Elpenor - first falling from the loft and then being left unburied. At least he finally gets his burial. Meeting the dead and various children/wives whom the gods had affairs with was interesting. Thought it was a bit odd that he mentions Leda being Castor and Pollux' mother but not Clytemnestra and Helen's. Also personally I always supported Clytemnestra killing Agamemnon who seemed like a total tool, but Homer seems to disagree.
The bit where the ship is destroyed is very dramatic. I can picture that working well in the movie. Another slightly odd simile there at the end of ch12 about Charybdis belching up the mast "as one who spends the whole day judging quarrels between young men, at last goes home to eat". Not sure what he's eluding there.
I was interested in the human tongues part you mentioned Shackleton and found this:
Homer describes Circe's island as a place of mystery and danger. Her home is described as a grand stone palace, befitting a Mycenaean king, yet it stands isolated on an island. Circe herself is introduced as a "dread goddess of human voice," a description that highlights her unique position in the Greek pantheon - divine yet accessible to mortals.
I also found this Reddit thread which discussed human voice in Homer:

Also as an aside, Telemachus possibly ends up marrying Circe after Odysseus dies which is interesting in itself. ( not in Homer)
