Priam, King of Troy, begging for Hector's body:

"'Honor the gods, Achilles; pity him.
Think of your father; I'm more pitiful;
I've suffered what no other mortal has,
I've kissed the hand of one who killed my children.'
He spoke, and stirred Achilles' grief to tears;
He gently pushed the old man's hand away.
They both remembered; Priam wept for Hector,
Sitting crouched before Achilles' feet.
Achilles mourned his father, then again
Patroculs, and their mourning stirred the house."
