Diomedes is a figure in Greek mythology. He was considered the bravest of all Greek warriors and was said to be more feared by his enemies than Achilles himself during the Trojan War. His parents are Ares and Cyrene.
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 her son Aeneas, and Ares with some assistance by Athena. He was one of the best Greek heroes in that war besides Achilles. 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.
