Where are you rushing now?
What is this madness blazing in your hearts?
Zeus forbids you to fight for Achaea’s armies!
– Homer
The Iliad, Book 8, lines 473-475. With the Trojans and Hector routing the Greeks, Hera and Athena prepare for battle, but messenger goddess Iris blocks their path and tells them Zeus’s orders. They are forbidden to fight for the Greeks.
