The name Celaeno (Greek Κελαινώ, 'the dark one') is used by classical sources and modern summaries for multiple, distinct mythic figures rather than a single origin narrative. As a Pleiad, Celaeno is one of the Seven Sisters whose mythic identity is transferred to a named star (identified in modern star catalogs with 16 Tauri). As a Harpy, Celaeno appears in the epic cycle represented in Vergil's Aeneid, where Harpies inhabit the Strophades islands and interact with Aeneas. Other occurrences of the name belong to genealogical and local-myth contexts (a Danaid who marries and kills Hyperbius; a Phocian princess, an Amazon slain by Heracles; and women named Celaeno cited as mothers of various offspring by gods), reflecting a pattern of name-reuse across genealogical and heroic traditions (sources: Wikipedia summary entries; Vergil/Aeneid summaries; astronomy star catalog notes).
Descriptions vary by attestation. As a Pleiad, Celaeno is an identified star within the Pleiades cluster (modern astronomy links the name to the star 16 Tauri) and thus is treated as a celestial sister rather than a detailed anthropomorphic figure. As a Harpy, classical tradition portrays Harpies as winged, snatching creatures (from Greek harpazo, 'to snatch'); Vergilian-derived summaries place a winged Harpy figure called Celaeno at the Strophades. The mortal bearers of the name (Danaid, Phocian princess, Amazon, mothers in genealogies) are cited as named human women in genealogical lists and epic episodes; explicit physical descriptions for these mortal figures are not provided in the cited summaries.
Attested behaviors differ with each role. The Harpy called Celaeno in the Aeneid context both obstructs and speaks prophetic warnings or prophecies to Aeneas about his future journeys (Vergil/Aeneid summaries). The Pleiad Celaeno functions as a named member of a stellar cluster (no direct agency recorded in the cited astronomical sources beyond identification with the star 16 Tauri). Mortal figures named Celaeno participate in recurring mythic actions: one Danaid marries and kills her husband (a pattern in the Danaid cycle), an Amazon of that name is slain by Heracles, and other maternal attributions link bearers of the name to offspring by gods (Poseidon, Apollo) or heroes in genealogical accounts. The sources do not present a unified set of supernatural powers shared by all bearers of the name.

Pleiades
The Pleiades is an asterism — the open star cluster Messier 45 — visible as a compact group of bright stars and, in many cultures, personified as a set of mythic figures (notably the Seven Sisters in Greek myth). It functions both as a concrete astronomical object and as a widespread cultural calendrical and mythic motif used to mark seasons, navigation, and genealogies.

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.
