The individual akhos of the Achilles figure leads to the collective akhos of the Achaean host during the Battle of the Ships, but it was their own earlier akhos during the plague that had led to Achilles' akhos.
Nagy demonstrates that akhos operates as a bidirectional, causally recursive force linking the hero's individual grief to the collective suffering of the lāos, establishing the structural logic of the Iliad's plot.
