Which Greek hero dueled with Hector in Book 7 of the Iliad?

The Greek hero who dueled with Hector in Book 7 of the Iliad was Ajax the Great. When Hector challenges the Achaeans to single combat, nine Greek leaders volunteer, and the army chooses Ajax by lot.

Ajax is one of the strongest Greek warriors after Achilles. He fights with a huge shield, a long spear, and exceptional physical strength. His duel with Hector lasts through much of the day. Ajax wounds Hector with his spear and knocks him down with a massive stone, but Hector survives and continues the fight.

The heralds eventually stop the contest as night approaches. Neither warrior is defeated, and they exchange gifts: Ajax gives Hector a sword and belt, while Hector gives Ajax a sword. The exchange reflects the epic’s unusual respect between opposing champions.

This Ajax is Ajax the Great, son of Telamon, not Ajax the Lesser, who is a separate Greek commander. Diomedes also appears among the warriors who volunteer, but he is not selected for the Book 7 duel.
