In Greek heroic genealogies Megareus is presented as a king of Onchestus who in the generation of the Minos–Theseus cycle came to Megara as an ally. Sources vary on his parentage: some traditions name him son of Poseidon and Oenope (or of the eponym Onchestus), reflecting the common Greek pattern of partial divine descent for local heroes. He is placed in the narrative sequence of the Cretan war, aiding King Nisus of Megara against Minos and meeting his death in that campaign. Later local memory at Megara preserved a tomb identified as his.
Surviving source excerpts provide no detailed physical description. He is treated as a mortal/heroic king commemorated by a tomb at Megara, implying human corporeality and burial, but no attributes of dress, age, or specific heroic accoutrements are recorded in the supplied texts.
Megareus' 'abilities' in the sources are social and martial rather than supernatural: he rules as king of Onchestus, leads or brings military aid to Megara in the Cretan invasion, and fights in inter-polis war. Some genealogical traditions grant him divine parentage (son of Poseidon), which situates him within the sacralized heroic category typical of Greek local-founders but does not in the provided material indicate explicit magical powers.

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.

Minos
Minos is a legendary Cretan king in ancient Greek myth, remembered as a lawgiver and founder of Cretan naval power in life and as one of the three judges of the dead in Hades after death. Classical sources present him as a semi-divine, politically powerful mortal (son of Zeus and Europa) whose authority is both terrestrial and judicial in the afterlife.

Theseus
Theseus is a legendary hero of Greek myth credited with clearing dangers from Attic roads, slaying the Minotaur, and performing foundational civic acts for Athens (including synoikismos and establishing cult practice). He is portrayed as of mixed mortal and divine parentage and functions as a culture-hero and exemplar in later authors' moralizing biographies.
*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.
