Glaucus and Diomedes
Glaucus and Diomedes meet as enemies at Troy, but the discovery of an inherited bond of guest-friendship prevents them from fighting.
The Story
During the fighting at Troy, Diomedes encountered a warrior he did not recognise.
The man was Glaucus, a Lycian ally of Troy and companion of Sarpedon.
Before attacking, Diomedes asked who he was.
Glaucus answered by describing his ancestry.
His family line led back through Bellerophon.
Diomedes suddenly recognised an old connection.
His own grandfather Oeneus had once received Bellerophon as a guest.
The families had exchanged gifts and established a bond of guest-friendship.
That relationship survived across generations.
Although Glaucus and Diomedes now stood on opposite sides of the Trojan War, they agreed not to fight one another.
They exchanged armour as a sign of the inherited friendship.
Homer then adds an unusual detail.
Glaucus exchanged golden armour for Diomedes' bronze equipment, a trade described as dramatically unequal in value.
The episode interrupts the violence of the Iliad with a reminder that older social obligations could cross even the dividing lines of war.
