In Hesiodic genealogies Nereus is the eldest son of Pontus (the Sea) and Gaia (the Earth). He becomes father, with the Oceanid Doris, of fifty daughters known as the Nereids and of a son Nerites in some later accounts. As an archaic sea-personification he occupies a primordial place in Greek cosmogony, an ancestral marine power later overlain in prominence by Olympian deities such as Poseidon.
Literary tradition describes Nereus as an aged, bearded sea-god — Hesiod calls him trustworthy and gentle — and Attic vase-painting commonly depicts him as a draped torso issuing from a long, coiling scaly fish-like tail, often holding a staff of authority. He is visually and thematically allied with the broader 'Old Man of the Sea' iconography found in Greek art.
Sources portray Nereus as truthful and morally steady (Hesiod's 'tells no lies') and as possessing prophetic knowledge. He shares with other 'Old Man of the Sea' figures the motif of shapeshifting: heroes who could seize such a sea-elder while he was changing form could compel prophetic speech. Literary tradition therefore treats him as a helpful prophetic source for heroes (parallel to Proteus) rather than as a malignant force.
Weaknesses
- conditioncan be compelled to reveal prophecy if seized or restrained during shapeshifting (shared Old Man of the Sea motif)
Wards
None recorded.

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.
*Péh₂usōn (reconstructed)
Péh₂usōn is a hypothetical Proto‑Indo‑European pastoral guardian reconstructed by comparative scholars from parallels in Greek and Vedic traditions. Proposed as a Graeco‑Aryan ancestor‑figure, the reconstruction describes a protector of flocks, roads, and travellers rather than an attested historical cultic personality.
Aba (disambiguation / name-form)
Aba is a polyvalent name-form attested across many unrelated contexts (place names, personal names, animal names, and brief mythological listings). The provided sources do not support a single, coherent supernatural entity called "Aba" and offer no descriptive or ritual material for such a being.
Abarbarea
Abarbarea is a name attested in classical Greek and Roman sources for freshwater nymphs (naiads). The name appears for at least two individual mythic figures — a naiad wife of Bucolion and a naiad counted among ancestors of the Tyrians — and Hesychius records plural forms that may indicate the name was also used as a class-name (Abarbareai / Abarbalaiai).
Abas
Abas (Ancient Greek: Ἄβας, gen.: Ἄβαντος) is not a single mythic being but a recurring personal name borne by multiple mortals and minor mythic figures in Greek epic and genealogical traditions — kings, founders, seers, warriors, attendants, a centaur, and a youth transformed by a goddess. The name is glossed in the sources as 'guileless' or 'good-hearted' and appears across Argive, Theban, Trojan, Euboean, and other local cycles.
Abderus
Abderus (Ancient Greek: Ἄβδηρος, romanized Ábdēros) is a mortal heroic figure in Greek myth closely associated with Heracles, remembered as the youth left in charge of the Mares of Diomedes who was killed by them. He functions as an eponymous local/divine-hero ancestor for the city of Abdera and received funerary commemoration and athletic agones at his tomb.
Abomination of Desolation
An apocalyptic prophetic phrase originating in the Book of Daniel designating a profaning thing or act that renders the Jerusalem Temple cult desolate; later reused in the Synoptic Gospels as an eschatological sign prompting urgent flight. The term denotes ritual/cultic impurity (Hebrew shiqquts) and is variously interpreted as pagan offerings or altar, a foreign cult statue, or (in some New Testament readings) an acting agent.
Absyrtus
Absyrtus (Ancient Greek: Ἄψυρτος) is a Colchian prince in the Greek Argonautic cycle, son of King Aeëtes and brother or half-brother of Medea. He appears in variant traditions either as a companion taken by Medea during her flight with Jason and murdered/dismembered to delay pursuit, or as a pursuer sent by Aeëtes who is overtaken and slain by Jason; his death functions as a key narrative device in the escape from Colchis.
Acacallis
Acacallis (Ancient Greek: Ἀκακαλλίς; also Acalle) is a mythological princess of Crete in Greek tradition, daughter of King Minos and Pasiphae. She functions primarily as a dynastic and etiological figure: in varying accounts she is mother, by gods such as Hermes (Mercury) or Apollo, of eponymous or founder-figures like Cydon (founder of Cydonia), Miletus, or Lydon/ Lydus.
Acacus
Acacus (Ancient Greek: Ἄκακος) is, in Arcadian Greek tradition, a mortal eponymous founder-king of Acacesium and is remembered as the foster-father who reared the infant Hermes (Mercury) in that local tradition. He is presented in genealogies as a son of Lycaon and functions as a local ancestral/onomastic figure rather than a supernatural spirit.
Academus
Academus (Greek: Akádemos / Hekádemos) is an Attic hero-eponym tied to a sacred grove (Akademeia) on the Cephissus near Athens. In myth he revealed where Helen was hidden to the Dioskouroi, an act said to have saved the city, and the place bearing his name became a long-lived sacred precinct, later the site of Plato's Academy.
Acamas
Acamas (Ancient Greek: Ἀκάμας) is a personal name recurrent in ancient Greek narrative traditions applied to multiple human characters (warriors, princes, suitors), once to a Cyclops, and once as a hound's name. Rather than a single supernatural entity, bearers of the name appear episodically across the Trojan War, Theseid, and Theban cycles as mortal actors whose deeds intersect with gods and fate.
Acantha
Acantha (Ancient Greek: Ἀκάνθα, 'thorn') is a late or secondary mythological figure known from modern retellings as a nymph transformed into the acanthus plant. The tale that she scratched Apollo and was changed into a spiny-leaved plant is not attested in surviving classical corpora and appears to be a modern compilation or invention rather than a firmly documented ancient myth.
