The tradition groups multiple genealogies and origins: primordial water powers such as Oceanus, Tethys and Pontus stand as foundational or cosmogonic figures; the Olympian Poseidon functions as the chief god of the sea and is associated with horses and civic patronage; elder prophetic sea‑figures (Nereus, Proteus, Glaucus, Phorcys) occupy an archaic 'Old Man of the Sea' type and father clusters of nymphs and monsters; heroized mortals like Ino are transformed into cult figures (Leucothea) and receive worship. Together these figures map water as both a material and symbolic source in Greek cosmology and ritual life.
No single uniform iconography is prescribed across the class. Sources portray the 'Old Man of the Sea' figures as shape‑shifters who may appear variably and father either 'radiantly beautiful' nymph daughters (the Nereids) or hideous monsters; nymphs are presented as beautiful female figures; Phorcys is linked to monstrous progeny while Leucothea is described in sources as a 'shadowy sea‑deity' and her name glossed as 'white goddess'. Detailed visual attributes (specific garments, colors, hybrid anatomies) are not supplied in the cited material.
Members of the class exhibit a range of mythic functions: the Old Man figures are shape‑shifters and prophets; Poseidon is mythically credited with control over the sea and creation of horses and functions as a major patron of cities and seafaring; elder sea powers father nymphs and monsters whose names often encode metaphorical or geographical meanings; liminal figures like Leucothea mediate thresholds to the Otherworld and receive ritual offerings in contexts that mix mourning and worship. The tradition also frames human maritime skill—shipbuilding and navigation—as a principle for negotiating these powers.

Nereids
Nereids are the class of female sea-nymphs in Greek myth, traditionally the fifty daughters of Nereus and the Oceanid Doris, associated especially with the Aegean Sea. They appear as beautiful young women who dwell in the sea and form the retinue of major sea-deities, acting as benevolent helpers of sailors and participants in mythic narratives.
Oceanus
Oceanus (Greek: Ὠκεανός) is a primordial Titan in ancient Greek cosmology who personifies the great river that encircles the world and is named as father of the river gods (potamoi) and the Oceanids. He functions as a cosmological boundary-stream and genealogical progenitor in multiple Greek traditions and appears in literary theogonies and Greco-Roman art.
Tethys
Tethys is attested in the provided materials primarily as a Titaness of Greek mythic tradition who in a modern children's retelling is presented as an elderly storyteller and mediator among gods. The name is also widely reused in scientific and cultural contexts (a Saturnian moon, a gastropod genus, the ancient Tethys Ocean, and various institutions), usages which are naming transfers rather than continuations of the mythic figure.
Pontus
Pontus is attested in the supplied sources primarily as a Greek theonym meaning "sea" (Πόντος, Póntos) and as a geographic/ethnic designation for the region on the southern coast of the Black Sea. The corpus does not provide evidence of Pontus functioning as a discrete, living folkloric spirit with attendant rituals or abilities.
Poseidon
Poseidon is a principal deity of the ancient Greek pantheon, counted among the Twelve Olympians; he presides over the sea, storms, earthquakes and horses and functions as protector of seafarers and guardian of cities and colonies.
Nereus
Nereus is an archaic Greek sea-god, eldest son of Pontus and Gaia, known as an aged, truthful 'Old Man of the Sea' who fathers the Nereids and functions as a source of prophetic counsel; he shares traits with other sea-elders like Proteus and later recedes in prominence beneath Poseidon.
Proteus
Proteus is an ancient Greek sea-associated divine figure—an 'Old Man of the Sea'—noted for prophetic knowledge and the ability to assume many forms. He is typically portrayed as a subordinate sea-deity (often described as a son of Poseidon) who resists disclosure of hidden truths unless compelled by capture.
Glaucus
In classical Greek myth, Glaucus is a former mortal fisherman who became a sea-associated divine figure after contact with a magical herb. He is portrayed as a prophetic sea-being who dwells among the Nereids, is consulted by sailors and voyagers for prophecy, and appears in episodic myths (Argonauts, Menelaus, the Scylla/Circe cycle).
Phorcys
Phorcys (Ancient Greek: Φόρκυς) is a primordial sea deity in Greek myth, presented in Hesiodic genealogy as a son of Pontus and Gaia. Paired with Ceto, he is chiefly noted as the progenitor of a brood of archaic, often monstrous marine and chthonic beings and appears in iconography as a hybrid merman-monster in Hellenistic–Roman art.
Thetis
Thetis is a figure from ancient Greek myth: a sea-nymph (one of the fifty Nereids) and a semi-divine water-goddess. She is mother of Achilles, a shapeshifter and protector who intervenes for gods and heroes, and a liminal figure tied to older sea-divinities and questions of mortality and divine succession.
Castor and Pollux (the Dioscuri)
A pair of mythic twin brothers of Greek and Roman tradition (the Dioscuri/Gemini) who occupy a liminal heroic/divine status. They function as patrons and protectors of sailors, travellers, horsemen and athletes, and are ultimately placed among the stars as the constellation Gemini.
Ceto
Ceto (Ancient Greek: Κητώ, Kētṓ) is a primordial sea goddess in Greek mythic cosmology, daughter of Pontus and Gaia, primarily notable as the maternal progenitor of various named monstrous beings (e.g., the Graeae and Gorgons) by Phorcys. Her name is etymologically linked to the common Greek term for sea-monster (kētos), and she functions chiefly as a genealogical and cosmological figure rather than an active, individualized actor in surviving narratives.
