Excerpt 1, Athene:

Then in answer the goddess grey-eyed Athene spoke to him:
"Father of the shining bolt, dark misted, what is this you said?
Do you wish to bring back a man who is mortal, one long since
doomed by his destiny, from ill-sounding death and release him?
Do it, then; but not all the rest of us gods shall approve you.”

Excerpt 2, Achilleus:

But looking darkly at him swift-footed Achilleus answered:
"No more entreating of me, you dog, by knees or parents.
I wish only that my spirit and fury would drive me
to hack your meat away and eat it raw for the things that
you have done to me. So there is no one who can hold the dogs off
from your head, not if they bring here and set before me ten times
and twenty times the ransom, and promise more in addition . . .”
