Classical sources present variant accounts. One tradition reports that the Castalian Spring already existed when Apollo came to Delphi searching for Python. Another account, recorded for example by Lactantius Placidus in commentary on Statius, relates that the nymph Castalia, pursued by Apollo's amorous advances, threw herself into a fountain at Delphi (or at the base of Mount Parnassus or at Mount Helicon) and was transformed into the spring that thereafter bore her name. Apollo is later said to have consecrated the spring to the Muses (Castaliae Musae).
Literary tradition characterizes Castalia as a "young nymph" (a naiad) but supplies no sustained physical portrait; classical summaries identify her as a humanlike water-nymph rather than giving detailed bodily or dress features. Equally, the Castalian Spring is described as a sacred spring near Delphi (also variably placed at the base of Mount Parnassus or on Mount Helicon) without elaborate geographic description in the provided sources.
Sources attribute to the spring (and by extension to Castalia) the power to inspire poetic genius: "those who drank her waters or listened to their quiet sound" received poetic inspiration. The waters also had a ritual, practical function in the sanctuary: they were used to clean Delphian temples. Castalia's mythic behavior includes metamorphosis or self-immersion to escape Apollo, a common motif in nymph narratives; she is integrated into the network of river-god genealogies as a daughter of Achelous and stands in ritual relation to Apollo and the Muses.

Apsara
Celestial dancers and water nymphs of Hindu cosmology — beautiful semi-divine beings who dance at the court of Indra and, by his command, descend to earth to distract sages from excessive asceticism.

Apollo
Olympian deity of ancient Greek religion associated with prophecy, healing, music, archery, purification, and civic order. Principal patron of the Delphic oracle, protector of youth and flocks, and ambivalently both healer and bringer of plague.
Acis and Galatea
A pair of lovers from ancient Greek myth: Galatea is a Nereid (sea-nymph) traditionally counted among the daughters of Nereus and Doris; Acis is a mortal youth in classical accounts who, in Ovid's poetic version, is killed by the Cyclops Polyphemus and transformed by Galatea into a river-spirit, explaining a Sicilian stream.
Actaeon
A mortal hunter of Greek myth who, in multiple traditions, is transformed into a stag and torn apart by his own hounds after transgressing the goddess Artemis. He functions as a mythic exemplar about proper deference to divine boundaries and, in some locales, became the focus of cultic rites and memorials.
Aesepus
Aesepus is the personified river-god (potamos) of the Aesepus River in the Troad / northern Mysia of Anatolia. Attested in Hesiod's catalogue of river-children and in Homeric and geographic passages, Aesepus functions primarily as a topographical divine ancestor and eponym for a town and local genealogies.
Aethra
Aethra (Ancient Greek: Αἴθρα, romanized Aithra, lit. 'bright sky') is a name borne by multiple women in Greek myth, most prominently a princess of Troezen who is mother of the hero Theseus. In some traditions an Aethra is also listed among Oceanids, indicating a separate, water‑nymph identity in certain genealogies.
Aganippe (naiad)
Aganippe is the local Naiad of the spring called Aganippe at the base of Mount Helicon in Boeotia. The spring and its nymph are traditionally associated with the Muses and with poetic inspiration; the name Aganippe is also used as an epithet in other, sometimes divergent, local mythic or cultic contexts.
Alegenor
Alegenor (Ancient Greek: Ἀλεγήνωρ) is a minor mortal figure in Greek mythic genealogies, attested as a son of Itonus and the father of Clonius and Promachus. He functions in the sources as a genealogical ancestor situating his more active descendants among the Boeotian leaders of the Trojan War rather than as an independently acting supernatural being.
Alexander (name / epithet)
Alexander is primarily an Ancient Greek personal name (Ἀλέξανδρος, Aléxandros) meaning 'defender/protector of men.' In the assembled sources it functions as an anthroponym and occasional divine epithet (e.g., Hera Alexandros) rather than a single, discrete supernatural entity with a consistent mythic ontology.
Alexida
Alexida (Ancient Greek: Ἀλεξίδη) is an attested mythological figure in Greek literary tradition, presented as a daughter of Amphiaraus and the eponymous ancestress from whom the Elasioi (Elasii), averters of epileptic fits, were believed in Argos to descend. She is preserved in surviving references as a genealogical origin rather than an active cultic agent.
Alpheus
Alpheus (Ancient Greek: Ἀλφειός) is the personified river and river-god of the Alpheios in the Peloponnese. He is classed among the river-deities descended from Oceanus and Tethys and appears in myths linking the Arcadian/Elian river to the Sicilian well Arethusa, to Artemis, and to the labors of Heracles.
Amalthea
Amalthea (Ancient Greek Ἀμάλθεια) is a figure of Greek myth most commonly identified as the nurse of the infant Zeus. Traditions variously portray her as a nymph who tended a goat that fed Zeus or, in later Hellenistic treatments, as the goat itself; she is also associated with the "horn of Amalthea" (cornucopia), a horn reputed to yield inexhaustible food and drink.
Amnisiades
The Amnisiades (Ancient Greek: Αμνισιαδες / Αμνισιδες) are a group of naiads — freshwater nymphs — associated with the Amnisos river in Crete. They are attested in Hellenistic poetry as members of Artemis's retinue and are linked by scholarship to cult activity at a cave of Eileithyia on the Amnisos.
Amphictyon
Amphictyon (Greek: Ἀμφικτύων) is a mytho-historical ancestral king in Greek tradition associated with the generation after the great flood and with the foundation/organization of communities that dwelt around sanctuaries (the Amphictyons). He appears in variant genealogies as son of Deucalion and Pyrrha or as son of Hellen, is called king of Thermopylae and in some accounts king of Athens, and is etiologically linked to the Amphictyonic League and early cultic practice.
