Zeus flung Strife on Achaea’s fast ships,
the brutal goddess flaring his storm-shield,
his monstrous sign of war in both her fists.
She stood on Odysseus’ huge black-bellied hull,
moored mid-line so a shout could reach both wings,
…There Strife took her stand, raising her high-pitched cry,
great and terrible, lashing the fighting-fury
in each Achaean’s heart – no stopping them now,
mad for war and struggle. Now, suddenly,
battle thrilled them more than the journey home,
than sailing hollow ships to their dear native land.
– Homer
The Iliad, Book 11, lines 3-7, 11-16. Zeus sets the goddess Strife upon the Greeks, encouraging them to fight. The gods make a regular thing of intervening in the human world in The Iliad, often causing chaos in the process. Strife unleashes her rage and in the process provokes the fighting fury of the Achaeans, making them mad for war.
