Oceanus

• 1. Introduction

  ›

  Oceanus once heard himself mocked by his own kin: "How did you summon courage to quit the stream that bears your name and the rock-roofed caves you yourself have made...?" Ancient Greek storytellers made Oceanus a Titan, child of Uranus, the Sky, and Gaia, the Earth, and ruler of the immense river said to encircle the whole world. Who spoke to him with such scorn, and why did he not answer in kind? Where does a name like his even come from, given that scholars still call its origin obscure? Was Oceanus, rather than Uranus and Gaia, the true first parent of every god, as some ancient poets hinted? Did he take a side when his own family went to war, not once but twice? And if his river had no beginning and no end, curling back into itself forever, where did the ancient Greeks think it actually flowed, and how did later mapmakers go looking for it?

• 2. A Name Without Origin

  ›

  Linguist M. L. West called the origin of the name Oceanus "obscure," adding that it "cannot be explained from Greek." Pherecydes of Syros once wrote the name as Ōgenós, a form that supports the idea it came from another language entirely. Even so, West found no foreign model convincing enough to settle the question. Several scholars have proposed a Semitic origin for the name instead. R. S. P. Beekes argued for a different source: a loanword from the Aegean region's Pre-Greek substrate, spoken before Indo-European languages arrived. Michael Janda takes the opposite view, seeing possible Indo-European roots in the word after all. Whatever its true origin, the name attached itself to a god Hesiod placed at the very top of a sprawling family tree.

  Hesiod placed Oceanus as the eldest of the Titans, ahead of eleven siblings born to Uranus and Gaia. Those siblings were Coeus, Crius, Hyperion, Iapetus, Theia, Rhea, Themis, Mnemosyne, Phoebe, Tethys, and Cronus. Oceanus married his own sister Tethys, and with her fathered two vast families: the river gods, all sons, and the Oceanids, all daughters. Hesiod counted three thousand river gods, a number meant to convey that they were beyond counting. Achelous, god of the largest river in Greece, gave his daughter in marriage to Alcmaeon. He then lost a wrestling match against Heracles for the right to marry Deianira. Alpheus fell in love with the nymph Arethusa and chased her to Syracuse, where Artemis turned her into a spring. Scamander fought for the Trojans in the Trojan War. Enraged when Achilles clogged his waters with a large number of Trojan corpses, Scamander rose in flood and nearly drowned Achilles. Hesiod likewise counted three thousand Oceanid daughters. Metis was Zeus's first wife; he made her pregnant with Athena and then swallowed her whole. Eurynome, Zeus's third wife, became mother of the Charites. Doris married Nereus and mothered the Nereids. Callirhoe married Chrysaor and mothered Geryon. Clymene married Iapetus and bore Atlas, Menoetius, Prometheus, and Epimetheus. Perseis married Helios and mothered Circe and Aeetes. Idyia married Aeetes and mothered Medea. Styx, the great river of the underworld, married Pallas, and with him had Zelus, Nike, Kratos, and Bia. According to Epimenides's Theogony, Oceanus fathered the Harpies with Gaia, and by the same account fathered Triptolemus with her too. Nonnus, in his Dionysiaca, called "the lakes" liquid daughters cut off from Oceanos. Oceanus was also said to have fathered the trickster Cercopes on his own daughter Theia. That tangle of parentage would later raise an even bigger question: whether Oceanus, not Uranus and Gaia, was the true first parent of every god.

• 4. First Parents Of The Gods

  In a section of the Iliad known as the Deception of Zeus, Hera twice calls the pair "Oceanus, from whom the gods are sprung, and mother Tethys." M. L. West read these lines as evidence of a myth in which Oceanus and Tethys, not Uranus and Gaia, were "the first parents of the whole race of gods." Classicist Timothy Gantz pushed back on that reading. He noted that "mother" could simply mean Tethys had been Hera's foster mother for a time, since Hera says exactly that in the very next lines. Gantz suggested the "genesis of the gods" phrase might only be a formulaic epithet. It could simply point to the countless rivers and springs descended from Okeanos, comparable to lines elsewhere in the Iliad at 21.195-197. A later passage in the Iliad has the god Hypnos call Oceanus "genesis for all." Gantz argued this phrase is hard to read as anything but Homer treating Oceanus as father of the Titans. Plato's Timaeus offers a genealogy, likely Orphic, that may have tried to reconcile Homer and Hesiod. In it, Uranus and Gaia parent Oceanus and Tethys, who in turn parent Cronus, Rhea, the other Titans, and a figure named Phorcys. In his Cratylus, Plato quotes Orpheus calling Oceanus and Tethys "the first to marry." That line may point to an Orphic theogony making the pair, not Uranus and Gaia, the primeval parents. Plato counts Phorcys as a Titan alongside Cronus and Rhea, and the mythographer Apollodorus adds a thirteenth Titan, Dione, mother of Aphrodite by Zeus. Together, the two accounts hint at an Orphic tradition in which Phorcys and Dione stood in for Oceanus and Tethys among Hesiod's twelve Titans. Epimenides traced an even stranger lineage. Night and Aer, the first two beings, produced Tartarus. Tartarus then produced two Titans, possibly Oceanus and Tethys, from whom the world egg came. None of these competing genealogies quite settled whether Oceanus ever raised a hand in the conflicts that split his family apart.

  When Cronus, youngest of the Titans, overthrew his father Uranus to seize the cosmos, Hesiod says none of the other Titans took part. The mythographer Apollodorus tells it differently: every Titan except Oceanus joined Cronus in attacking Uranus. Proclus, commenting on Plato's Timaeus, quotes lines from a probably Orphic poem. In it, an angry Oceanus weighs whether to join Cronus and the other Titans against Uranus. Proclus states that Oceanus, in the end, did not take part. Oceanus also stayed out of the Titanomachy, the war in which Zeus and the Olympians fought Cronus and the Titans for control of the cosmos. After that war put Cronus and the other Titans in chains, Oceanus remained free. Hesiod has Oceanus send his daughter Styx, along with her children Zelus, Nike, Cratos, and Bia, to fight on Zeus's side. In the Iliad, Hera says she was sent to Oceanus and Tethys for safekeeping during the war. Sometime after that war, Aeschylus's Prometheus Bound has Oceanus ride a winged steed to visit Prometheus, his nephew, chained to a rock for stealing fire. Oceanus says he is sympathetic and wishes to help if he can. Prometheus mocks him instead, then later tells him: "I envy you because you have escaped blame for having dared to share with me in my troubles." Before that reply, Oceanus advises Prometheus to humble himself before Zeus, the new ruler, rather than make his situation worse. According to Pherecydes, Oceanus once challenged Heracles directly. Heracles once crossed the sea in Helios's golden cup, heading to Erytheia to steal the cattle of Geryon. Oceanus sent high waves to rock the cup. Heracles threatened to shoot him with his bow, and Oceanus, afraid, backed down. That same golden cup carried Heracles toward a river god's realm that Greek writers pictured as the very edge of the world.

• 6. The River At World's End

  ›

  Hesiod twice calls Oceanus "the perfect river," while Homer describes "the stream of the river Oceanus." Both poets also call him "backflowing," since the great stream circles the earth and empties back into itself. Hesiod adds "deep-swirling," and Homer "deep-flowing." Homer says Oceanus "bounds the Earth," and artists placed him encircling the rim of both the shield of Achilles and the shield of Heracles. Hesiod's Theogony sets Oceanus near Tartarus, while the Iliad places him near Elysium. In the Odyssey, heroes must cross him to reach the "dank house of Hades." For both poets, Oceanus marked the boundary past which the world turned fantastical. Beyond his stream, the Theogony places the Hesperides with their golden apples, the three-headed giant Geryon, and the snake-haired Gorgons. Homer instead places the Cimmerians, the Aethiopians, and the Pygmies near Oceanus's banks. Homer has the sun god Helios rise from Oceanus each morning in the east. Each evening Helios sinks back into him in the west, while the stars bathe in his stream. Later sources add that Helios then sails back east through the night along Oceanus. Homer says that from Oceanus "all rivers flow and every sea, and all the springs and deep wells." That role as universal source implies Oceanus was fresh water, distinct from the sea, and Hesiod seems to separate him from Pontus, the sea's personification. Elsewhere the line blurs: Hesiod has Nereus and Thaumas, both sons of Pontus, marry daughters of Oceanus. Homer, who never mentions Pontus at all, has Thetis, daughter of Nereus, living alongside Eurynome, daughter of Oceanus. In practice, Oceanus could stand for the sea itself just as easily as for a river. That same picture of a world-circling god would inspire vase painters and sculptors for centuries afterward.

  An early sixth-century BC Attic black-figure vase, the "Erskine" dinos, was made by Sophilos and is held at the British Museum, catalogued as 1971.111-1.1. It shows Oceanus identified by inscription. He appears near the end of a long procession of gods arriving at the wedding of Peleus and Thetis. He follows a chariot driven by Athena, which carries Artemis. Oceanus has bull horns, holds a snake in his left hand and a fish in his right, and has a fish's body below the waist. Tethys and Eileithyia follow close behind him, with Hephaestus on his mule closing the procession. A similar early sixth-century BC Attic black-figure vase is the François Vase, held in Florence under the number 4209. It shows Oceanus again at the end of the same wedding procession. Hephaestus's mule again brings up the rear. Little of Oceanus survives on this vase, but he was apparently given a bull's head there too. Fragments of a second Sophilos vase in Athens, labeled Akr 587, repeat the same guest order, suggesting all three drew on a shared literary source. On the second-century BC Pergamon Altar, a labeled Oceanus fights among the gods battling the Giants in the Gigantomachy frieze. He stands half nude, facing right, against a giant who is falling. Fragments nearby are thought to belong to Tethys. They include a scrap of chiton beneath Oceanus's left arm and a hand gripping a large tree branch behind his head. In Hellenistic and Roman mosaics, Oceanus commonly appears with a muscular man's upper body, a long beard, and horns often shaped like a crab's claws. His lower body becomes a serpent, recalling depictions of the monster Typhon. Cartographers of later centuries tried to plot that same encircling stream onto the actual edges of the known world.

• 8. Mapping The Edge Of Knowledge

  Herodotus rejected a theory held by some of his contemporaries: that the mighty Oceanus caused the Nile's summer floods. "For my part I know of no river called Ocean," he wrote, "and I think that Homer, or one of the earlier poets, invented the name, and introduced it into his poetry." Classicist Timothy Gantz argues Oceanus originally stood for a freshwater river circling the world, feeding every spring and river on it. As Greek geography grew more accurate, the name shifted onto the stranger, less charted waters of the Atlantic, also called the "Ocean Sea." A newer god, Poseidon, took over the Mediterranean instead. The Roman geographer Pomponius Mela wrote that the inhabited earth "is entirely surrounded by the Ocean, from which it receives four seas." Those four were the Caspian Sea, the Persian Gulf, the Arabian Gulf, and the Mediterranean. The Greek geographer Ptolemy later split this single Ocean into several distinct oceans. One of them, the Western Ocean, today's Atlantic, was often simply called "the Ocean," including by Julius Caesar. Odysseus's journey to the sunless land of the Cimmerians, said to lie beyond Oceanus, later fed a tradition equating the river with the Black Sea. In the fourth century BC, Hecataeus of Abdera wrote about the Oceanus of the Hyperboreans. He said it was neither the Arctic nor the Western Ocean, but the sea north of the Greek world. That sea was the Black Sea, which Herodotus called "the most admirable of all seas." Pomponius Mela and Dionysius Periegetes both labeled it the "immense sea," and medieval maps named it Mare majus. Apollonius of Rhodes likewise called the lower Danube the Kéras Okeanoío, the "Gulf" or "Horn of Oceanus." Hecataeus of Abdera also described a holy island sacred to Pelasgian, and later Greek, Apollo, sitting in the westernmost reach of the Okeanós Potamós. It went by several names across the ages: Leuke, Leukos, Alba, and Fidonisi, or Isle of Snakes. One version of the legend has the hero Achilles buried there in a hilly tumulus. The site was later wrongly linked to the modern town of Kiliya at the Danube Delta. In the fourth century AD, Avienius's Gaulish Latin work Ora maritima applies the word Accion, meaning "ocean," to great lakes far from any sea. That same Gaulish word, Accion, shows how far the idea of an ocean had drifted, from a world-circling river god to the name for landlocked lakes.
