Chapman's translation of the Iliad is archaic and difficult to understand, while Rieu's translation is modernized and more accessible to contemporary readers.
Achilles' baneful wrath resound, O Goddess, that impos'd
Infinite sorrows on the Greeks, and many brave souls loos'd
From breasts heroic; sent them far to that invisible cave
That no light comforts; and their limbs to dogs and vultures gave:
To all which Jove's will gave effect; from whom first strife begun
Betwixt Atrides, king of men, and Thetis' godlike son.
Anger — sing, goddess, the anger of Achilles son of Peleus, that accursed anger, which brought the Greeks endless sufferings and sent the mighty souls of many warriors to Hades, leaving their bodies as carrion for the dogs and a feast for the birds; and Zeus' purpose was fulfilled. It all began when Agamemnon lord of men and godlike Achilles quarrelled and parted.
