Orthrus is presented in the mythic corpus as a monstrous offspring of the primordial monsters Echidna and Typhon. As such he belongs to the family of hybrid chthonic monsters produced by that pair. Hesiod and later mythographic tradition place Orthrus in this lineage and also name him as the father of other monstrous beings (e.g., the Sphinx and the Nemean Lion in Hesiod), though maternal identity for those offspring is uncertain in the sources.
Literary and artistic sources consistently present Orthrus as a multi-headed dog, with Apollodorus describing him as two-headed. Artistic depictions vary: many show two heads, some show a single head, and at least one early Cypriot relief depicts three heads. The tail is usually shown as a normal dog tail in many representations, while some vase-paintings and reliefs portray a serpentine tail. Other iconographic variants show Orthrus wounded, pierced by arrows, or lying on his back.
Orthrus functions primarily as a guardian-beast: he is charged with watching Geryon's herd of red cattle on Erytheia and serves as a watch/guard hound attached to his master (Eurytion) and to the herd. His parentage (Echidna and Typhon) situates him among dangerous, unnatural monsters in Greek mythic taxonomy. In the narrative of Heracles' tenth labour Orthrus is overcome and killed by Heracles (Apollodorus states Heracles killed him with his club), though visual traditions sometimes portray arrows as the weapon causing his death. Hesiod additionally records Orthrus as sire of later monsters, linking him genealogically to other mythic threats.

Wards
None recorded.
Cerberus
The three-headed hound of Hades, guardian of the underworld's gates — welcoming the dead in but allowing no shade to leave and no living mortal to enter uninvited.
Echidna
The 'Mother of Monsters' — half beautiful woman, half enormous serpent — who with Typhon gave birth to nearly every great monster of Greek mythology.
Typhon
The last great monster of Greek mythology — a vast, fire-breathing giant whose shoulders sprouted a hundred serpent heads, nearly toppling Zeus from Olympus.
Nemean Lion
A singular monstrous lion of Greek myth that terrorized the region of Nemea and was slain by Heracles as the first of his Twelve Labours. Noted for an impervious golden hide and claws 'sharper than mortal swords,' its pelt becomes Heracles' emblem and protective mantle.
Geryon
Geryon is a monstrous, martial figure from Greek heroic-age mythology who dwells on the far-western island Erytheia and guards a valuable herd of red cattle; he is best known as the opponent slain by Heracles in the Tenth Labour. Classical sources present multiple, conflicting physical descriptions; later reception (notably Dante) recasts the name as an allegorical composite monster.
*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.
