Final answer:
In the Iliad, Glaucus and Diomedes trade armor on the battlefield, symbolizing a moment of humanity and respect.
Step-by-step explanation:
Glaucus and Diomedes exchanged gifts on the battlefield instead of fighting. This event is well-known from Homer's epic poem, the Iliad, which is set during the Trojan War. In a remarkable display of mutual respect and recognition of shared heritage and guest-friendship ties, they traded armor. Glaucus, a Trojan ally, exchanged his golden armor for the bronze armor of Diomedes, a Greek warrior. This act symbolizes a moment of humanity amidst the brutality of war, highlighting the complex code of honor that warriors of that era followed.
