Diomedes

The mist Athena removes

An arrow strikes Diomedes in the shoulder, and he asks Sthenelus to pull it out. Blood runs over his armour. Diomedes then prays to Athena, asking for the man who shot him to come within reach of his spear.

Athena answers by making his limbs light and placing in him the strength she gave his father, Tydeus. She also removes the mist from his eyes so that he can distinguish a god from a mortal in battle. The gift arrives with a restriction: he must not fight any immortal except Aphrodite.

The condition matters more than the improved sight. Diomedes can recognise powers other warriors cannot, but recognition does not give him authority over them. His greatest actions in the Iliad depend on when Athena permits him to cross that boundary.

Why he wounds Aphrodite

Aphrodite enters the fighting to carry her wounded son Aeneas away. Diomedes sees her and follows, knowing she is the one goddess Athena named as an exception. His spear pierces the skin between Aphrodite’s wrist and palm, and divine ichor flows from the wound.

He then charges Aeneas even though Apollo has taken the Trojan into his arms. Three times Diomedes advances and three times Apollo drives him back. On the fourth attempt the god warns him that mortals and immortals do not hold equal rank. Diomedes withdraws.

The two encounters set the edge of his power. He wounds Aphrodite because Athena has authorised it. He cannot pass Apollo, however fiercely he attacks. Seeing a god clearly means knowing both when to strike and when the order has run out.

What changes when Ares enters the battle

Later in Book 5, Diomedes gives ground when he sees Ares directing the Trojans. Athena finds him and accuses him of falling short of Tydeus. Diomedes answers that fear has not stopped him. He is obeying her command not to fight the other gods.

Athena now changes the command. She tells him to drive at Ares, removes Sthenelus from the chariot and takes the reins herself. When Ares throws his spear, Athena catches it and turns it aside. Diomedes casts next, but she guides his weapon into the god’s body.

Ares roars and leaves the field for Olympus. Diomedes has wounded a second god, yet every part of the attack depends on the goddess beside him: the permission, the chariot’s course, his survival and the spear’s path. The feat belongs to his obedience as much as to his courage.

Why he plants his spear before Glaucus

Diomedes meets the Lycian Glaucus between the armies and asks who he is. Glaucus answers with his family history, reaching back to Bellerophon. Diomedes recognises a connection made before either warrior was born: his grandfather Oeneus once received Bellerophon as a guest for twenty days.

He plants his spear in the ground. The two men agree to avoid each other in battle, clasp hands and exchange armour so both armies can see the inherited friendship. Homer notes that Glaucus gives gold for bronze, but the unequal exchange does not cancel their agreement.

Against the gods, Diomedes acts inside Athena’s changing limits. With Glaucus, no deity needs to stop his hand. A story about their grandfathers is enough to turn an armed meeting into recognition.

What Argos remembered

The Catalogue of Ships makes Diomedes one of three commanders over the men of Argos, walled Tiryns, Hermione, Asine, Troezen, Epidaurus, Aegina and Mases. Eighty ships carry that contingent to Troy. Apollodorus gives him an Argive mother, Deipyle, and a father who came to Argos in exile.

Nestor says Diomedes brings his company back to Argos on the fourth day after the returning fleet separates. Pausanias later records a sanctuary there dedicated by the hero to Athena Oxyderces, whose name means Sharp-sighted. Its explanation returns to the moment in Book 5 when the goddess takes the mist from his eyes.

The sanctuary fixes a divine gift to the ground Diomedes led. Argos remembers him not with the wound he gave Aphrodite or Ares, but with the sight that told him they were gods.
