In variants summarized in the supplied sources, the narrative opens with Eglė bathing at a lake or sea-lagoon (marios) where she finds a coiled grass-snake (žaltys/žalčius). The snake demands that she pledge herself in exchange for the return of her clothing; she agrees and becomes the serpent's wife. The male serpent identifies himself as Žilvinas, escorts her to a palace beneath the sea (reached via a nearby island and an underground tunnel), and establishes an otherworldly household and family with her. The tale functions as an aetiology: after betrayal and the serpent's death, Eglė transforms her children and eventually herself into trees whose species-names correspond to the characters' names, explaining local arboreal identities.
Sources present the being in two primary registers: as a coiled grass-snake (žaltys/žalčius) at the water's edge that speaks and as a handsome man—described in summaries as the grass-snake prince—when greeting Eglė and escorting her to the underwater palace. The serpent's principal domain is an underwater or subterranean palace beneath a sea-lagoon; visual depictions and theatrical/sculptural commemorations emphasize a royal, otherworldly household rather than a simple animal lair. The lexical term žalčius is ambiguous in the sources and may refer to a terrestrial grass snake or evoke an aquatic/mithical serpent (possibly comparable to an eel) in the tale's seascape.
Documented tale actions attribute to Žilvinas speech, intelligence, the capacity to take a human wife and father children, rule an underwater palace, impose conditions and tasks on his bride, and teach a secret chant by which he may be summoned from the sea. He sets tests (three tasks in motifs) and prescribes limits on Eglė's surface visits. The tale also shows that, once summoned ashore by the chant and brought to land, he can be attacked and killed by humans in the narrative variant provided. The story includes metamorphic magic enacted by Eglė (a whispered enchantment) that turns humans into specified tree species, but explicit ritual formulas or wider destructive powers for Žilvinas beyond those narrative capacities are not recorded in the supplied sources.

Alka
Alka (plural alkas) is a class of sacred natural places in pre-Christian Baltic religion—Latvian and Lithuanian—functioning as set-apart cult sites where offerings and sacrifices were made. Treated as holy ground rather than a single anthropomorphic spirit, alkas served as loci connecting communities with ancestors and otherworldly realms and frequently appear in toponyms across the Baltic landscape.
Auseklis
Auseklis is a named youthful celestial being in Latvian folk-song tradition (dainas), associated with the dawn and a particular eight-pointed star emblem. He appears among the Dieva dēli (sons of Dievs) as an attendant of the Sun (Saule), a suitor in the mythic 'celestial wedding', and a participant in household-like sky rituals.
Aušrinė
Aušrinė is the Lithuanian personification and deity of the morning star (planet Venus) in traditional Baltic cosmology. She is a feminine liminal figure associated with dawn, beauty, youth, love, health and renewal who appears each morning to prepare the way for Saulė (the Sun).

Dievas
Dievas (Lithuanian; Dievs in Latvian; Diews in Old Prussian) is the primordial supreme sky deity in Baltic religion, understood as the luminous sky-dome, a creator and ruler of gods, and a god of light, prosperity and time. The lexeme is a Baltic reflex of Proto-Indo-European *Dyēus and, following Christianization, the same word came to denote the Christian God.
Dievs (Dievas)
Dievs (Latvian Dievs; Lithuanian Dievas) is the primordial sky‑father of the Baltic traditional pantheon, presented in sources as a supreme luminous sky power, creator and ruler of the gods, and associated with light, prosperity, and cosmic order. The theonym survives in modern Latvian language and civic/religious usage but the supplied corpus gives little on specific myths, iconography, or ritual praxis tied to the pre‑Christian figure.
Gabija
Gabija is the Lithuanian household fire spirit and protector of the hearth and family. Treated as a living presence in the home, she is cared for through routine domestic practices (feeding, covering embers, providing water) and is held responsible in folklore for wandering or destructive fires when offended or neglected.
Jumala
Jumala is a divine name and concept in Finnic and some Volga‑Finnic language communities, referring both to pre‑Christian sky‑deity figures (often associated with sky, thunder, storms and fertility) and, after Christianization, to the Christian God as the ordinary word for 'God'. It functions variably as a proper name, a generic term for deity, or the designation of local sky gods in regional traditions.
