Styx, the eldest daughter of Ocean and Tethys, stood as the chiefest among the Oceanids.1,2,3 She was a deathless nymph with long hair, her presence dark and frowning upon the abysmal shades.4,5,6 Her waters were sad and unlovely, resembling wine in both smell and color, while the stream itself appeared small.7,8,9
Styx was the wife of Pallas and bore four children who would become central to divine power.10,3 Among her offspring were Nike, the trim-ankled Victory, and Zelus, known as Emulation.6,10,4 She also gave birth to Cratos, who represented Strength, and Bia, who represented Force.6,10,4 Other accounts name Echidna as her child, born to a man named Peiras, while some sources list her as the mother of Persephone.11,12 Her siblings included Asia, Electra, Doris, Eurynome, Amphitrite, Metis, and Philyra.1,13
When Zeus rose against the Titans, Styx and her children fought alongside him in the great conflict.14,6 She arrived at Olympus first among the gods to aid Zeus, coming with her children by using her father's wit.6 Zeus honored Styx by making oaths be sworn by her water.14,15 He sent Iris to retrieve the water, which served as the source for the great oath of the gods.14,15 This water bound the oaths of the gods, a role it maintained in later ages.16
The river Styx was located within the realm of Hades, where its water flowed from a high and beetling rock.14,17 It was a branch of the river Oceanus that flowed beneath the earth, with a tenth of Oceanus's water allotted to it.15 Styx acted as a ninefold barrier to keep the dead contained, hemming in the way of the deceased in vengeful wrath.17,18,19 A grim oarsman ferried the dead across these waters, and the river's sheer streams could have prevented Heracles from escaping Hades.20,21
Styx lived apart from the gods, her waters mixed with sulphur by the Telchines.22,23 During the judgment of souls, she accused the gods of committing perjury.24 Her waters were used for libation in golden basins before battles against the Giants and Titans.25 Though feared and loathed, she remained the eternal and primaeval water that bound the divine word.15,6
