Diomedes
A formidable Argive hero of the Trojan War.

Overview
Diomedes is one of the most formidable Achaean fighters in the Iliad, and his success is inseparable from Athena’s guidance. In Book 5 the goddess gives him exceptional strength and sight capable of recognising gods, initially permitting him to attack only Aphrodite among them. As the battle escalates, she personally encourages and guides him in wounding Ares. Diomedes can touch divine bodies, yet he retreats when Apollo warns him, marking a boundary to heroic force. In Book 6 he questions Glaucus before fighting, discovers inherited guest-friendship between their grandfathers, and exchanges armour instead. Recognition, memory and restraint are as important to his heroism as violent achievement.
