Thoughts on the Odyssey, the Iliiad, and Homer's unwritten volume 3

After the blood-spattered conclusion to The Odyssey - anyone who's read it remembers how Odysseus, Telemachus, and two loyal subjects overcome and massacre the suitors in the sealed off dining chamber, the screams of terror echoing throughout the palace - O shows some mercy to two of the hangers-on who plead for their lives, saying they did no wrong - one was the poet whom the suitors had coerced into providing some entertainment, no surprise the Homer would let him off the hook - and O is pretty vindictive against the handmaids whom he believes have become prostitutes for the suitors - but can you blame them? They were slaves - looking for the best, the only, opportunity for survival. Long odd scene of his reunion with the ever-tearful Penelope; nobody can doubt her unearthly devotion to him, or perhaps to his memory, but isn't it odd that the nursemaid, even the dog, recognize O on his return but she does not, even after a very long conversation with O in disguise? It's very touching that, after all the tribulation and bloodshed, the epic concludes with O's visit to his now-widowed father, Laertes, on his remote farm - a kind of pastoral conclusion to this oceanic voyage. Thinking back, it strikes me that there's an obvious contrast between the Iliad and the Odyssey (there are many but I'll pont out one): the Iliad is about attack or penetration - trying the get inside the walls of Troy, finally achieved through O's cunning; the Odyssey is about escape - from many imprisonments and enchantments, most dramatically from the cave of the Cyclops. Another final note: O spoke several times about his concern about killing all of the suitors; they're all from powerful families, most of them on the island of Ithaca I think, and O is rightly concerned about any or all of the families attacking his palace and seeking revenge. That's still an outstanding issue at the conclusion; is it possible that Homer was pondering a 3rd volume?
