In Greek myth Thetis is one of the fifty Nereids, daughters of the sea-god Nereus and the Oceanid Doris. She belongs to an older generation of sea-divinities associated with figures such as Tethys; literary tradition places her within the network of Homeric and Hesiodic gods, attending Olympian events (notably her wedding) and interacting with both gods and mortals. A prophecy that a son of Thetis would surpass his father motivates Zeus and Poseidon to arrange for her marriage to the mortal Peleus, a plot point that links her to questions of divine succession.
As a Nereid Thetis is portrayed as a female sea-deity or sea-nymph typical of Homeric imagery, appearing at the sea or its edge. In key narratives she demonstrates shapeshifting abilities: when resisting Peleus she changes form — becoming flame, water, a raging lioness, and a serpent — before being restrained. She is otherwise depicted in the roles of a nurturing attendant and a divine refuge-giver, appearing in scenes of caring or shelter at sea and on islands such as Lemnos.
Thetis is able to shapeshift into elemental and animal forms (flame, water, lioness, serpent) as attested in the marriage narrative. She functions as a kourotrophos (nurse/protector) to heroes (most famously Achilles) and aids gods (sheltering Hephaestus after his fall, giving refuge to Dionysus in narrative recollection). Mythic tradition ascribes to her a capacity to affect the boundary between mortality and immortality: one account describes her nightly ritual of burning away her infant son's mortality and anointing him with ambrosia by day, a process interrupted by Peleus that explains Achilles' retained mortality. Her potential to bear a child greater than his father has cosmological and political consequences among the gods.
Weaknesses
- conditionNo ancient vulnerability specified
Wards
- otherNo ancient wards attested in the supplied sources

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.

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.

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.
*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.
