Δεξαμενος Dexamenos Dexamenus --

DEXAMENOS (or Dexamenus) was a king of the Akhaian towns of Olenos, Boura and Dyme in the north-western corner of the Peloponnesos. He was a close friend of Herakles who slew the kentauros (centaur) Eurytion when he tried to force a marriagewith Dexamenos' daughter Mnesimakhe.

Dexamenos was probably a descendant of Endymion, through Epeios and Alektor. Alektor preceded him as king of Olenos. Dexamenos was in turn succeeded on the throne by (his son or brother?) Hipponoos. However, during his reign, the country was invaded and annexed by King Oineus of Aitolia. Homer describes Olenos as an Aitolian possession around the time of the Trojan War.

DEXAMENUS (Dexamenos), a king of Olenus, and the father of Deïaneira, whom Heracles seduced during his stay with Dexamenus, who had hospitably received him. Heracles on parting promised to return and marry her. But in his absence the centaur Eurytion sued for Deïaneira's hand, and her father out of fear promised her to him. On the wedding day Heracles returned and slew Eurytion. (Hygin. Fab. 33.) Deïaneira is usually called a daughter of Oeneus, but Apollodorus (ii. 5. § 5) calls the daughter of Dexamenus, Mnesimache, and Diodorus (iv. 33) Hippolyte.

Iophon of Athens, Dexamenus (lost play) (Greek tragedy C5th B.C.) :
According to the Suda the minor Athenian dramatist Iophon wrote a play entitled Dexamenos, which presumably told the story of Herakles and the kentauros (centaur) Eurytion.

Cleophon of Athens, Dexamenus (lost play) (Greek tragedy C5th B.C.) :
Cleophon also dramatised the story of Dexamenos.

Pseudo-Apollodorus, Bibliotheca 2. 91 (trans. Frazer) (Greek mythographer C2nd A.D.) :
"[King Augeias of Elis refused to pay Herakles for the cleaning of his stables, and arbitrators were called to settle the dispute.] The arbitrators having taken their seats, Phyleus [son of Augeias] was called by Hercules and bore witness against his father, affirming that he had agreed to give him a reward. In a rage Augeias, before the voting took place, ordered both Phyleus and Herakles to pack out of Elis. So Phyleus went to Doulikhion and dwelt there, and Herakles repaired to Dexamenos at Olenos. He found Dexamenos on the point of betrothing perforce his daughter Mnesimakhe to the kentauros (centaur) Eurytion, and being called upon by him for help, he slew Eurytion when that kentauros came to fetch his bride."

Callimachus, Hymn 4 to Delos 104 ff (trans. Mair) (Greek poet C3rd B.C.) :
"The Akhaian cities . . . Helike, the companion of Poseidon, and Boura, the steading of Dexamenos, the son of Oikeus."

Diodorus Siculus, Library of History 4. 69. 2 (trans. Oldfather) (Greek historian C1st B.C.) :
"As for the sons of Lapithes, Phorbas went to Olenos, from which city Alektor, the king of Eleia, summoned him to come to his aid, since he stood in fear of the overlordship of Pelops, and he gave him a share of the kingship of Elis; and to Phorbas were born two sons, Aigeus [i.e. Augeas] and Aktor, who received the kingship over the Eleians."
[N.B. Alektor was presumably the father of Dexamenos, the next king to rule Olenos. The daughters of Dexamenos married the sons of Aktor.]

Diodorus Siculus, Library of History 4. 33. 1 :
"[After the completion of his Twelve Labours] Heracles returned to the Peloponnesos and set out against Aegeas, since the latter had defrauded him of his reward.89 It came to a battle between him and the Eleans, but on this occasion he had no success and so returned to Olenos to Dexamenos. The latter’s daughter Hippolyte was being joined in marriage to Azan [an Arkadian prince], and when Herakles, as he sat at the wedding feast, observed the kentauros (centaur) Eurytion acting in an insulting manner towards Hippolyte and endeavoured to do violence to her, he slew him."

Pausanias, Description of Greece 7. 18. 1 (trans. Jones) (Greek travelogue C2nd A.D.) :
"Some forty stades from Dyme the river Peiros flows down into the sea; on the Peiros once stood the Akhaian city of Olenos. The poets who have sung of Herakles and his labours have found a favorite subject in Dexamenos, king of Olenos, and the entertainment Herakles received at his court. That Olenos was from the beginning a small town I find confirmed in an elegiac poem composed by Hermesianax [Greek elegiac poet C4th B.C.] about Eurytion the Kentauros."

Pausanias, Description of Greece 7. 19. 6 - 10 :
"[In the Akhaian town of Patrai :] The sacrifice to Artemis of human beings is said to have ceased in this way. An oracle had been given from Delphoi to the Patraians even before this, to the effect that a strange king would come to the land, bringing with him a strange divinity, and this king would put an end to the sacrifice to Triklaria. When Troy was captured, and the Greeks divided the spoils, Eurypylos the son of Euaimon [or son of Dexamenos, see below] got a chest. In it was an image of Dionysos, the work, so they say, of Hephaistos, and given as a gift by Zeus to Dardanos . . . Eurypylos opened the chest, saw the image, and forthwith on seeing it went mad. He continued to be insane for the greater part of the time, with rare lucid intervals. Being in this condition he did not proceed on his voyage to Thessaly, but made for the town and gulf of Kirrha. Going up to Delphoi he inquired of the oracle about his illness.
They say that the oracle given him was to the effect that where he should come across a people offering a strange sacrifice, there he was to set down the chest and make his home. Now the ships of Eurypylos were carried down by the wind to the sea off Aroe. On landing he came across a youth and a maiden who had been brought to the altar of Triklaria. So Eurypylos found it easy to understand about the sacrifice, while the people of the place remembered their oracle seeing a king whom they had never seen before, they also suspected that the chest had some god inside it.
And so the malady of Eurypylos and the sacrifice of these people came to an end, and the river was given its present name Meilikhos. Certain writers have said that the events I have related happened not to the Thessalian Eurypylos, but to Eurypylos the son of Dexamenos who was king in Olenos, holding that this man joined Herakles in his campaign against Troy and received the chest from Heracles. The rest of their story is the same as mine.
But I cannot bring myself to believe that Heracles did not know the facts about the chest, if they were as described, nor, if he were aware of them, do I think that he would ever have given it to an ally as a gift. Further, the people of Patrai have no tradition of a Eurypylos save the son of Euaimon, and to him every year they sacrifice as to a hero, when they celebrate the festival in honor of Dionysos."

Pausanias, Description of Greece 5. 3. 3 :
"When Phyleus [son of Augeas] had returned to Dulikhion after organizing the affairs of Elis, Augeas died at an advanced age, and the kingdom of Elis devolved on Agasthenes, the son of Augeas, and on Amphimakhos and Thalpios. For the sons of Aktor [i.e. the twins Kteatos and Eurytos] married twin sisters, the daughters of Dexamenos who was king at Olenos; Amphimakhos was born to one son and Theronike, Thalpios to her sister Theraiphone and Eurytos . . . Incidentally this is shown by Homer in his list of the Eleians; he makes their whole fleet to consist of forty ships, half of them under the command of Amphimakhos and Thalpios."

Pseudo-Hyginus, Fabulae 31 (trans. Grant) (Roman mythographer C2nd A.D.) :
"Incidental labours of Hercules . . . He killed Eurytion the Centaur because he wooed Dejanira, daughter of Dexamenus, his hoped-for bride."

Pseudo-Hyginus, Fabulae 33 :
"When Hercules had come to the court of King Dexamenus and had violated his daughter Dejanira, promising he would marry her, Eurytion a Centaurus, son of Ixion and Nubes [Nephele], after his departure sought Dejanira as a wife. Her father, fearing violence, promised her to him. On the appointed day he came with his brothers to the wedding. Hercules intervened, and killed the Centaur, and led home his betrothed."
[N.B. Deianeira was usually named as a daughter of King Oineus of Kalydon, while Dexamenos' daughter was Mnesimakhe.]

Pseudo-Hyginus, Fabulae 81 (trans. Grant) (Roman mythographer C2nd A.D.) :
"Seven Kings who set out for Thebes. Adrastus, son of Talaus by Eurynome, daughter of Iphitus, an Argive . . .
Tydeus, son of Oeneus by the captive Periboea, a Calydonian . . .
Capaneus, son of Hipponous by Astynome, daughter of Talaus, sister of Adrastus, an Argive.
Hippomedon, son of Mnesimachus by Metidice, daughter of Talaus, sister of Adrastus, an Argive."
[N.B. Hipponoos and Mnesimakhos may have been sons of King Dexamenos of Olenos. Dexamenos had a daughter named Mnesimakhe, and Hipponoos was described as a king of Olenos. Adrastos' kingdom incorporated most of Akhaia, up to the border with Olenos.]

* Eleios-Heleios is the same figure. One tradition represents him as a son of Perseus and the heir of King Pelops, another makes him a grandson of King Endymion. He was confounded with the sun-god Helios.
** Augeias ruled the whole of Elis including the regions of Elis, Pisa, Bouprasion and Doulikhion. After his death the kingdom was divided into four autonomous parts.
*** Amarynkeus received a quarter of the kingdom of Augeias. One assumes his portion was Pisatis.
**** In the reign of Hipponoos, Olenos was annexed by King Oineus of Aitolia. It is listed as an Aitolian dominion in Homer's Catalogue of Ships.
