The Iliad tells the story of Achilles’ anger, but also encompasses, within its narrow focus, the whole of the Trojan War. The title promises “a poem about Ilium” (i.e. Troy), and the poem lives up to that description. The first books recapitulate the origins and early stages of the Trojan War.
Homeric word-order is unusually accommodating towards its English equivalent. Verbs usually come where you expect them, adjectives sit near their nouns. Compared to, say, the complex structures of a Pindaric ode, or the elliptical one-line exchanges of dramatic dialogue, Homer’s largely paratactic progression of ‘…and…but…when…then…’ presents his translator with few immediate problems.
