Diomedes
A young boy named Diomedes stood four years old when his father Tydeus died in the battle against Thebes. His grandfather Oeneus ruled Calydon, but Tydeus had been exiled for killing relatives before finding refuge at Argos. King Adrastus gave Tydeus hospitality and married him to his daughter Deipyle. They produced two children: a daughter named Comaetho and the son who would become the hero of this story. When Tydeus fell in the Seven against Thebes expedition, Athena withdrew her gift of immortality because he ate the brains of an enemy. Ten years later, the sons of the fallen champions gathered as the Epigoni to avenge their fathers. Alcmaeon led the group that stormed Thebes and tore down its walls. Diomedes returned home to find King Adrastus dead from grief over the loss of his own son Aegialeus. As the last male descendant of Adrastus, Diomedes ascended to the throne of Argos. He secured his rule by marrying Aegialia, the daughter of the deceased king. During his five-year reign, Diomedes brought wealth and stability to Argos while maintaining influence over Calydonian politics.
In Book V of Homer's epic, Athena placed valour into the heart of her champion warrior. She made fire flare from his shield and helmet as he began to slay Trojan warriors including Phegeus and Pandarus. When Pandarus wounded Diomedes with an arrow, she offered him special vision to distinguish gods from men. Her instructions commanded him to wound Aphrodite if she entered battle but warned him not to engage any other god. Diomedes killed Astynous, Hypeiron, Abas, Polyidus, Xanthus, Thoon, Echemmon, and Chromius before facing Aeneas. He crushed Aeneas' hip with a huge stone after the Trojan prince's mother fled in terror. Apollo rescued Aeneas and sent the wounded goddess back to Olympus. Disregarding advice, Diomedes attacked Apollo three times until the god warned him against matching himself with immortals. Later, Hera and Athena drove straight at Ares in a chariot. Diomedes threw his spear guided by Athena to wound the god of war in the stomach. This act made him the only human to injure two Olympians in a single day. In Book VI, Hector described Diomedes as mightiest of all because his rage filled men's souls with panic.
Diomedes migrated to Daunia in Apulia where King Daunus welcomed him into court. The king begged for help warring against the Messapians and promised land and marriage to his daughter Euippe. Diomedes agreed to the proposal and routed the enemy forces. He assigned land to his followers known as Dorians and vanquished tribes called Monadi and Dardi along with cities named Apina and Trica. He built the city of Argyrippa and once hosted Aeneas there. When Aeneas requested the return of the Palladium, Diomedes gave it to him after an oracle told him to restore the sacred image to a Trojan so he would no longer suffer disasters. Some traditions claim he sailed to Libya during a storm and was imprisoned by King Lycus who planned on sacrificing him to Ares. The king's daughter Callirrhoe loosed Diomedes from his bonds but later killed herself out of grief when he sailed away without acknowledgment. He eventually spoke that as punishment for his involvement at Troy he never reached his fatherland of Argos and never saw his beloved wife again. Birds pursued him and his soldiers everywhere they landed including sea cliffs.
Strabo lists four different traditions about the hero's life in Italy regarding his death. One tradition claims he died making a canal to the sea at Urium before returning home. Another says he stayed at Urium until the end of his life. A third tradition states he disappeared on Diomedea, the uninhabited island where Shearwaters formerly his companions live. The fourth tradition comes from the Heneti who claim Diomedes had a mysterious apotheosis. On San Nicola Island of the Tremiti Archipelago there is a Hellenic period tomb called Diomedes's Tomb. A legend explains that goddess Venus transformed men into birds named Diomedee so they could stand guard at the grave of their king. The family name for albatrosses is Diomedeidae and the genus name for great albatrosses is Diomedea. Votive offerings specifically addressing Diomedes were found within the island of Palagruža on the Adriatic. Strabo mentions votive offerings in the Daunian temple of Athena at Luceria addressed directly to the hero. At Argos during the festival of Athena his shield was carried through streets as a relic together with the Palladium. His statue was washed in the river Inachus while temples dedicated to him existed at Argyripa, Metapontum, and Thurii.
Homer's Iliad presents Diomedes as one of the best warriors alongside Ajax the Great and Agamemnon after Achilles. Dares the Phrygian illustrated him as stocky, brave, dignified, and austere yet loud at war-cry and hot-tempered. Hyginus and Pseudo-Apollodorus list him among suitors of Helen bound by oath to defend Menelaus against wrong done to his marriage. Hesiod does not include Diomedes in his list of suitors suggesting later additions may have extrapolated from his Catalogue of Ships listing. Quintus Smyrnaeus describes how Diomedes mourned Thersites when Achilles killed him for mocking the hero's love for Penthesileia. Ovid writes that Venulus came to the home of exiled Diomedes in vain but found him erecting walls with favour of Iapygian Daunus. Plutarch records traditions about the Palladium being brought to Argos or Italy depending on which version is followed. Virgil's Aeneid describes the beauty and prosperity of Diomedes' kingdom while detailing his refusal to fight Trojans again. Strabo claims votive offerings in the Daunian temple contained specific addresses to Diomedes proving widespread worship across the Adriatic coast.
Hero cults became much more commonplace from the beginning of the 8th century BCE onwards throughout several Greek cities. Diomedes' cults were situated predominantly in Cyprus, Metapontum, and other cities on the coast of the Adriatic Sea. Inscriptions on votive offerings found in temples and tombs confirm the popularity along the Eastern coast of Italy. The most distinct votive offerings actually found within the island of Palagruža on the Adriatic prove the extent of this devotion. Two islands named after the hero exist in the Palagruža archipelago believed to be uninhabited by some accounts. Heneti sacrificed a white horse to Diomedes in special groves where wild animals grew tame according to Strabo. Traces of worship exist in Greece also with statues at Argyripa, Metapontum, Thurii, and other places. A temple consecrated to Diomedes called 'The Timavo' stood at the Adriatic. At Argos his shield was carried through streets as a relic together with the Palladium during festivals dedicated to Athena. His armour was preserved in a temple of Athena at Luceria in Apulia while a gold chain appeared in a temple of Artemis in Peucetia.
Fellini's movie 8½ features a cardinal telling the story of Diomedes' companions turning into birds to actor Marcello Mastroianni. The genus name for great albatrosses remains Diomedea honoring the mythological figure who inspired such legends. Islands of Diomedes in the Adriatic Sea continue to bear his name today reflecting ancient traditions about his disappearance. Scholars study the Hellenic period tomb on San Nicola Island of the Tremiti Archipelago known as Diomedes's Tomb. Modern literature references the hero's exile to Italy and his reconciliation with Aeneas regarding the Palladium. Scientific nomenclature preserves his memory through bird families named after him including Diomedeidae. Historical accounts describe how he founded cities like Argyrippa, Brundusium, Canusium, and Venusia across southern Italy. These settlements demonstrate the lasting impact of his migration from Greece to the Italian peninsula following the Trojan War.
