when the sun goes down,
lay on a handsome feast – once we’ve avenged our shame.
Before then, for me at least, neither food nor drink
will travel down my throat, not with my friend dead,
there in my shelter, torn to shreds by the sharp bronze…
His feet turned to the door; stretched out for burial,
round him comrades mourning.
– Homer
The Iliad, Book 19, lines 247-253. Achilles has no taste for food and refuses to eat before going into battle, because he is mourning his dead friend Patroclus. He vows to only feast after they have avenged their shame.
