And the son of Hippolochus answered, “Mighty son of Tydeus, why ask me of my lineage? Men come and go as leaves year by year upon the trees. Those of autumn the wind sheds upon the ground, but when spring returns the forest buds forth with fresh ones. Even so is it with the generations of mankind, the new spring up as the old are passing away.”
~ The Iliad - Book VI (Samuel Butler Translation. p41 / v144)
The Iliad Book VI post 2. Glaucus talks proudly about his lineage to Diomed. Diomed mentions that he is an old friend of his family. They depart as friends.
In Book 6 of The Iliad, Diomed comes across Glaucus who is fighting bravely for the Trojans. He asks him if Glaucus is a god since he does not want to fight gods and incur their wrath. He had already wounded Venus earlier. He asks him about his lineage, and Glaucus tells his story. They discover that they has some shared connections. Is it true to say that if you know the life story of your enemy, you might discover a new friend? Or are some differences so deep that an enemy is an enemy?
