اوکئانوس یا اقیانوس (به یونانی: Ωκεανός)، خدای اقیانوسها.
او فرزند اورانوس (آسمان) و گایا (زمین) و از تیتانها بود. با خواهر خود تتیس ازدواج کرد و صاحب سه هزار فرزند (اوکئانیدها) شد. که پریان رودها، دریاها و دریاچهها بودند. نه او و نه همسرش در جنگ تیتانها با زئوس، همدست تیتانها نشدند و توانستند با آرامش و صلح زندگی کنند.
شجرهنامه آخایوس در اسطورهشناسی یونان[ویرایش]
Oceanus (//; Greek: Ὠκεανός Ōkeanós, pronounced [ɔːkeanós]), also known as Ogenus (Ὤγενος Ōgenos or Ὠγηνός Ōgēnos) or Ogen (Ὠγήν Ōgēn), was a divine figure in classical antiquity, believed by the ancient Greeks and Romans to be the divine personification of the ocean, which the Ancient Greeks perceived as an enormous river encircling the world.
R. S. P. Beekes has suggested a Pre-Greek proto-form *-kay-an-. In contrast, Michael Janda has reminded the scientific community of an earlier comparison of the Vedic dragon Vṛtra's attribute āśáyāna- "lying on [the waters]" and Greek Ὠκεανός (Ōkeanós), which he sees as phonetical equivalents of each other, both stemming from a Proto-Indo-European (PIE) root *ō-kei-ṃ[h1]no- "lying on", related to Greek κεῖσθαι (keîsthai "to lie"). Janda furthermore points to early depictions of Okeanos with a snake's body, which seem to confirm the mythological parallel with the Vedic dragon Vṛtra.
Another parallel naming can be found in Greek ποταμός (potamós "broad body of water") and Old English fæðm "embrace, envelopment, fathom" which is notably attested in the Old English poem Helena (v. 765) as dracan fæðme "embrace of the dragon" and is furthermore related (via Germanic *faþma "spreading, embrace") to Old Norse Faðmir or Fáfnir the well-known name of a dragon in the 13th century Völsunga saga; all three words derive from PIE *poth2mos "spreading, expansion" and thus bind together the Greek word for a "broad river, stream" with the Germanic expressions connected to the dragon's "embrace".
According to Homer, Oceanus was the ocean-stream at the margin of the habitable world (οἰκουμένη, oikouménē), the father of everything, limiting it from the underworld and flowing around the Elysium. Hence Odysseus has to traverse it in order to arrive in the realm of the dead. In the Iliad, Hera mentions her intended journey to her foster parents, namely "Oceanus, from whom they all are sprung":
Helios rises from the deep-flowing Oceanus in the east and at the end of the day sinks back into the Oceanus in the west. Also the other stars "bathe […] in the stream of Ocean". Oceanus is called βαθύρροος ("deep-flowing") and ἀψόρροος ("flowing back to itself, circular"), the latter quality being reflected in its depiction on the shield of Achilles:
In Greek mythology, this ocean-stream was personified as a Titan, the eldest son of Uranus and Gaia. Oceanus' consort is his sister Tethys, and from their union came the ocean nymphs, also referred to as the three-thousand Oceanids, and all the rivers of the world, fountains, and lakes.
In most variations of the war between the Titans and the Olympians, or Titanomachy, Oceanus, along with Prometheus and Themis, did not take the side of his fellow Titans against the Olympians, but instead withdrew from the conflict. In most variations of this myth, Oceanus also refused to side with Cronus in the latter's revolt against their father, Uranus. He is, it appears, some sort of an outlaw to the society of Gods, as he also does not—and unlike all the other river gods, his sons—take part in the convention of gods on Mount Olympus.
Besides, Oceanus appears as a representative of the archaic world that Heracles constantly threatened and bested. As such, the Suda identifies Oceanus and Tethys as the parents of the two Kerkopes, whom Heracles also bested. Heracles forced Helios to lend him his golden bowl, in order to cross the wide expanse of the Ocean on his trip to the Hesperides. When Oceanus tossed the bowl about, Heracles threatened him and stilled his waves. The journey of Heracles in the sun-bowl upon Oceanus became a favored theme among painters of Attic pottery.
In Hellenistic and Roman mosaics, this Titan was often depicted as having the upper body of a muscular man with a long beard and horns (often represented as the claws of a crab) and the lower body of a serpent (cfr. Typhon). On a fragmentary archaic vessel of circa 580 BC (British Museum 1971.11–1.1), among the gods arriving at the wedding of Peleus and the sea-nymph Thetis, is a fish-tailed Oceanus, with a fish in one hand and a serpent in the other, gifts of bounty and prophecy. In Roman mosaics, such as that from Bardo, he might carry a steering-oar and cradle a ship.
In cosmography and geography
Oceanus appears in Hellenic cosmography as well as myth. Both Homer and Hesiod refer to Okeanós Potamós, the "Ocean Stream". When Odysseus and Nestor walk together along the shore of the sounding sea they address their prayers "to the great Sea-god who girdles the world". Cartographers continued to represent the encircling equatorial stream much as it had appeared on Achilles' shield.
Herodotus was skeptical about the physical existence of Oceanus and rejected the reasoning—proposed by some of his coevals—according to which the uncommon phenomenon of the summerly Nile flood was caused by the river's connection to the mighty Oceanus. Speaking about the Oceanus myth itself he declared:
Some scholars[who?] believe that Oceanus originally represented all bodies of salt water, including the Mediterranean Sea and the Atlantic Ocean, the two largest bodies known to the ancient Greeks. However, as geography became more accurate, Oceanus came to represent the stranger, more unknown waters of the Atlantic Ocean (also called the "Ocean Sea"), while the newcomer of a later generation, Poseidon, ruled over the Mediterranean Sea.
Late attestations for an equation with the Black Sea abound, the cause being – as it appears – Odysseus' travel to the Cimmerians whose fatherland, lying beyond the Oceanus, is described as a country divested from sunlight. In the fourth century BC, Hecataeus of Abdera writes that the Oceanus of the Hyperboreans is neither the Arctic nor Western Ocean, but the sea located to the north of the ancient Greek world, namely the Black Sea, called "the most admirable of all seas" by Herodotus, labelled the "immense sea" by Pomponius Mela and by Dionysius Periegetes, and which is named Mare majus on medieval geographic maps. Apollonius of Rhodes, similarly, calls the lower Danube the Kéras Okeanoío ("Gulf" or "Horn of Oceanus").
Hecataeus of Abdera also refers to a holy island, sacred to the Pelasgian (and later, Greek) Apollo, situated in the easternmost part of the Okeanós Potamós, and called in different times Leuke or Leukos, Alba, Fidonisi or Isle of Snakes. It was on Leuke, in one version of his legend, that the hero Achilles, in a hilly tumulus, was buried (which is erroneously connected to the modern town of Kiliya, at the Danube delta). Accion ("ocean"), in the fourth century AD Gaulish Latin of Avienus' Ora maritima, was applied to great lakes.
