Diomedes

Diomedes (Διομήδης in Ancient Greek) is a figure in Greek mythology. His parents are Tydeus and Deipyle. Hercules, the greatest of all Greek heroes is his uncle.

History
Diomedes fought at the side of the Greeks during the Trojan War. He was one of the favorites of Athena and was able to wound two Olympians in a single day: Aphrodite when she was rescuing Aeneas; and Ares with some assistance by Athena. He was one of the best Greek heroes in that war besides Achilles, Ajax, and Odysseus. He led the Argive troops in that war as King of Argos and was one of the many warriors to sneak into Troy in the Trojan Horse. He was said to be the most courageous of all Greeks.

His weapon during the war was his father's sword, and he also had a golden cuirass (a piece of armor that protects the torso) that was blessed by Athena.

The Battle of the Labyrinth
Diomedes is mentioned by Eurytion and Geryon.

Weapons
The god Hephaestus made Diomedes' cuirass for him. He was the only Greek warrior apart from Achilles who carried such an arsenal of gear made by Hera's most skilled son. He also had a round shield with the mark of a boar. In combat, he also carried a spear as well as his father's sword and possessed a golden cuirass. This golden armor bore a crest of a boar on the breast. It was created by a mortal smith but was blessed by Athena, who gave it to Tydeus. When he died, it passed to Diomedes. A skilled smith created the sword for Tydeus, which bore designs of a lion and a big boar.
