With many books, translations are negligible, with two obvious exceptions, one is the Bible, and surprisingly the other is The Iliad. Each translation can give a different insight and feel to the story. Everyone will have a favorite. I have several.
"Rage--Goddess, sing the rage of Peleus' son Achilles,
Murderous, doomed, that cost the Achaeans countless losses,
hurling down to the House of Death so many souls,
great fighters' souls. But made their bodies carrion,
feasts for dogs and birds,
and the will of Zeus was moving towards its end.
Begin, Muse, when the two first broke and clashed,
Agamemnon lord of men and brilliant Achilles."
-Translated by Robert Fagles
"Sing, O Goddess, the anger of Achilles, son of Peleus, that brought countless ills upon the Achaeans. Many a brave soul did it send hurrying down to Hades, and many a heroes did it yield a prey to dogs and vultures for so were the counsels of Zeus fulfilled from the day on which the son of Atreus, king of men, and great Achilles first fell out with one another."
-Translated by Samuel Butler
Sing, Goddess, Achilles' rage,
Black and murderous, that cost the Greeks
Incalculable pain pitched countless souls
Of heroes into Hades' dark,
And let their bodies rot as feasts
For dogs and birds, as Zeus' will was done.
Begin with the clash between Agamemnon--
The Greek Warlord--and godlike Achilles."
-Translated by Stanley Lombardo
"Anger be now your song, immortal one,
Akhilleus' anger, doomed and ruinous,
that caused the Akhaians loss on bitter loss
and crowded brave souls into the undergloom,
leaving so many dead men--carrion
for dogs and birds; and the will of Zeus was done.
Begin it when the two men first contending
broke with one another--
the Lord Marshal Agamémnon, Atreus' son, and Prince Akhilleus."
-Translated by Translated by Robert Fitzgerald
"Sing, goddess, the anger of Peleus' son of Achilleus and its devastation, which puts pains thousandfold upon the Achains,
hurled in the multitudes to the house of Hades strong souls of heroes, but gave their bodies to be the delicate feasting of dogs, of all birds, and the will of Zeus was accomplished since that time when first there stood the division of conflict Atrecus' son the lord of men and brilliant Achilleus."
-Translated by Richmond Lattimore
You will find that some translations are easier to read but others are easier to listen to on recordings, lectures, Kindle, and the like.
Our story takes place in the ninth year of the ongoing war. We get some introduction to the first nine years but they are just a background to this tale of pride, sorrow and revenge. The story will also end abruptly before the end of the war.
We have the wide conflict between the Trojans and Achaeans over a matter of pride; the gods get to take sides and many times direct spears and shields.
Although the more focused conflict is the power struggle between two different types of power. That of Achilles, son of Peleus and the greatest individual warrior and that of Agamemnon, lord of men, whose power comes form position.
We are treated to a blow by blow inside story as to what each is thinking and an unvarnished description of the perils of war and the search for Arête (to be more like Aries, God of War.)
