Demigod daughter of Boreas (canonical-Hesiodic north-wind deity) by Oreithyia daughter of Erechtheus king of Athens. Sister of the winged Argonaut Boreads Calais and Zetes, and of the Boreid Chione (mother of Eumolpus by Poseidon). Married to Phineus the Thracian king and seer; mother of two sons (Plexippus and Pandion in the canonical name-pair, with multiple variant-name traditions preserved in the mythographic record). Falsely accused alongside her sons by Phineus's second wife Idaea; the sons were blinded and Cleopatra imprisoned and tortured. The canonical-Sophoclean treatment in Antigone 966-987 elevates her to one of the central tragic-paradigms of high-born Greek womanhood subjected to unjust suffering through stepmother-treachery — the Choral Ode pairs her fate with Antigone's own as part of the consolation-meditation on inescapable tragedy. Rescued (in some traditions) when her brothers the Boreads arrived as Argonauts at Salmydessus and freed her and her sons; the sons' sight was variously restored by the Boreads themselves or by Asclepius. Apollonian variant constrains the Boread-rescue scope through the Iris-oath structure following the Harpies-resolution. Her sons are canonically childless in the surviving traditions, terminating the demigod-line through her, but her structural-canonical role in the Phineus-and-Argonauts narrative-arc is foundational across the canonical Greek mythographic tradition.
