It’s such a great work of literature that we can’t really speak of any one ‘meaning’ or ‘message’. But I’d be interested to know what other people take from the Iliad.
Personally I think that the Iliad addresses the human condition - suffering - phmata, kedea, algea, etc. Though the poem is about war, it encompasses all sorts of suffering: death, old age, bereavment, orphans, widows… and the meaningless and futility of human life (as brought out by the contrast with the gods)
This human condition was I think of particular concern to the Greeks because they had no belief in a good afterlife or a caring god.
[This incidentally, is why I think the Iliad is more relevant than ever to a society which is become ever more atheistic; it’s certainly been relevant to me in coming to terms with atheism]
But in war human suffering is magnified. In normal life, we know that we will die but it probably won’t be tomorrow. In the Iliad you might die tomorrow, and suffering is everywhere. Thus the human condition becomes an immediate problem.
Some might say that heroic ‘kleos’ (fame) is the way to escape the meaningless and insignificance of human life. But I’m not sure that the poem really does say this; the glory of war proves little comfort for Achilles or Hektor.
Perhaps the answer is humanity. Book 24 shows how humanity and sympathy can relive suffering.
Perhaps the answer is to face death. Achilles and Hektor accept their death nobly.
Or perhaps the Iliad is trying to tell us that this is the way it has to be. If there were no death and no suffering we would be like the unattractive gods in the book. There would no morality, no glory, no nothing. Compared to human meaningless, divine meaningless seems even worse.
(remember what Sarpedon says to Glaukon in book 13 - if i were immortal I wouldn’t need to fight)
What do other people think?
