Inachus

The historian Pausanias describes him as the eldest king of Argos who named the river after himself and sacrificed to Hera.[19][23] He also notes that some said he was not a mortal, but a river. Inachus was also said to be first priest at Argos, the country was frequently called the land of Inachus.[8][24] Jerome and Eusebius (both citing Castor of Rhodes), and as even late as 1812, John Lemprière[25] euhemeristically asserted that he was the first king of Argos reigning for 50 years[26] (B.C. 1807[27]). Inachus divided the territories between his sons, Phegeus and Phoroneus who succeeded him as the second king of Argos. Inachus contemporary was Leucippus, the eight king of Sicyon.[2]

The ancients themselves made several attempts to explain the stories about Inachus: sometimes they looked upon him as a native of Argos, who after the deluge of Deucalion led the Argives from the mountains into the plains, and confined the waters within their proper channels. After rendering the province of Argolis inhabitable again, he then founded the city of Argos. Other times, the ancients regarded Inachus as an immigrant who had come across the sea as the leader of an Egyptian or Libyan colony, and had united the Pelasgians, whom he found scattered on the banks of the Inachus.[28] They who make Inachus to have come into Greece from beyond the sea regard his name as a Greek form for the Oriental term Enak, denoting “great” or “powerful,” and this last as the base of the Greek ἄναξ, “a king.”

In Virgil's Aeneid, Inachus is represented on Turnus's shield. Compare the Inachos or Brimos of the Eleusinian Mysteries.

Inachus and his river god brothers Cephissus and Asterion were mediators in a land dispute between Poseidon and Hera. When they judged that the land belonged to Hera, Poseidon took away their water out of anger. For this reason neither Inachus nor either of the other rivers provided any water except during rainy seasons. In Danaan founding myth, because of the springs of Argolid being dried up, King Danaus sent his daughters to draw water to counter this drought. One of these daughters, Amymone, in her search lay with Poseidon who revealed to her the springs at Lerna.[29][30] Otherwise, Poseidon was also said to flooded the greater part of the country as his revenge but Hera induced Poseidon to send the sea back. The Argives then made a sanctuary to Poseidon Prosclystius (Flooder) at the spot where the tide ebbed.[31]

In Prometheus Bound, Io was disturbed by visions during her sleep night after night, where Zeus lusted for her maidenhood but she initially rejected the god's advances. When Io gained the courage to tell Inachus about these haunting dreams, his father sent many messengers to consult the oracle of Pytho and Dodona so that he might discover what deed or word of his would find favor with the gods. But the messengers returned with report of oracles, riddling, obscure, and darkly worded. Then at last there came an unmistakable utterance to Inachus, charging and commanding him clearly that he must thrust forth Io from his house and native land to roam at large to the remotest confines of the earth because if Inachus would not follow the oracle's instructions, Zeus would hurled a fiery thunderbolt that would utterly destroy his whole race. The king yielding in obedience to such prophetic utterances of Loxias (Apollo), Inachus drove his daughter away and barred her from his house, against his' and Io's will.[32]

According to Ovid, Inachus was the only one absent when his fellow river gods, Sperchios, Enipeus, Amphrysos, Apidanus and Aeas, visited Peneus, father of Daphne. following the pursuit of his daughter by the god Apollo and her transformation into a laurel tree (they are not sure whether to congratulate or to condole Peneus).[33] It was explained that Inachus hid in his cave, deepening his waters with his tears, bewailing also for his daughter Io who was lost. Inachus and his naiad daughters did not recognize Io, whom Zeus had transformed into a cow so that she could avoid detection by his jealous wife, Hera.[34]

"And Inachus and all her [i.e. Io] sister Naiads knew her not, although she followed them, they knew her not, although she suffered them to touch her sides and praise her. When the ancient Inachus gathered sweet herbs and offered them to her, she licked his hands, kissing her father's palms, nor could she more restrain her falling tears. If only words as well as tears would flow, she might implore his aid and tell her name and all her sad misfortune; but, instead, she traced in dust the letters of her name with cloven hoof; and thus her sad estate was known."

At this, Inachus understood Io's condition, and, lamenting, wished for death, but acknowledged his godly status made this an impossibility. Io subsequently recovered her original form and came to be worshipped as a goddess.[35]

In the account of Diodorus Siculus, after Io's disappearance, Inachus sent forth Cyrnus, one of his men in high command, fitting him out with a considerable fleet, and ordered him to hunt for Io in every region and not to return unless he had got possession of her. And Cyrnus, after having wandered over many parts of the inhabited world without being able to find her, put ashore in Caria on the Cherronesus where he founded a city which bore his name Cyrnus.[36]

In a rare variant of the myth according to Parthenius, Inachus sent several men to search and attempt to find her daughter Io who had been captured by brigands (not Zeus this time). One of these was Lyrcus, the son of Phoroneus, who covered a vast deal of land and sea without finding the girl, and finally renounced the toilsome quest. But he was too much afraid of Inachus to return to Argos and went instead to Caunus, where he married Hilebia, daughter of King Aegialus.[37]

According to Plutarch, the river Inachus had before borne the name of Carmanor or Haliacmon. Afterwards it was called after Inachus, the son of Oceanus. After Zeus (Jupiter) had deflowered his daughter Io, Inachus pursued the deity close at the heels, abusing and cursing him all the way as he went. Which so offended Zeus, that he sent Tisiphone, one of the Furies, who haunted and plagued him to that degree, that he flung himself into the river Haliacmon, bearing his own name afterwards.[7]

Suda's account

Inachos, a king of Argos, founded a city which he named for the moon, Io, for that is what Argives call the moon. He also had a daughter Io; Pekos who is also Zeus abducted her and fathered a daughter, Libya, by her. And Io, lamenting her ruin, fled to the Silpion Mountain and there died. Her father and her brothers, when they learned this, built a shrine to her and called the place Iopolis and remained there until the end. And they performed a ritual in her memory, banging on each other's doors every year and saying 'io, io!'.[38]

Sophocles wrote an Inachos, probably a satyr play, which survives only in some papyrus fragments found at Oxyrhyncus and Tebtunis, Egypt;[39] in it Inachos is reduced from magnificence to misery through the unrequited love of Zeus[40] for his daughter Io. Hermes wears the cap of darkness, rendering him invisible, but plays the aulos, to the mystification of the satyrs; Argos and Iris, as a messenger of Hera both appear, a "stranger" turns Io into a heifer at the touch of a hand, and at the end, apparently, the satyrs are freed from their bondage, to become shepherds of Inachos.[41] An additional papyrus fragment of Sophocles' Inachos was published in 1960.[42]
