The opening lines of the Iliad give two apparent definitions of the poem's plot: the mēnis, "wrath," of Achilles, which, in the first line, the narrator asks the Muse to sing, and the Dios boulē, "plan of Zeus," which we learn In the fifth line was being accomplished through the deaths of the many Achaeans who perished as a consequence of Achilles' wrath. Both of these rather abstract formulations appear to correspond to the same specific course of events, which is set in motion in the first book of the poem: the scheme devised by Achilles and Zeus, with Thetis as their intermediary, to avenge and repair Achilles' loss of honor at the hands of Agamemnon through Trojan success in the war. This scheme or plot (in a literal sense) among the principal divine and human characters thus appears to define the plot (in a literary sense) of the poem in which it is narrated.
