Cassandra

Classical accounts present Cassandra as a daughter of King Priam of Troy and a priestess associated with Apollo. Variants explain her prophetic gift and its contrary effect variously: a widespread motif describes Apollo granting her the power of prophecy in exchange for sexual favours and then cursing her when she refused; Hyginus relates Cassandra falling asleep in Apollo's temple exhausted from practicing and denying Apollo sexual access, after which her true prophecies would not be believed; a later commentator (Tzetzes) gives a variant in which Cassandra and her brother Helenus are left overnight in Apollo's temple and wake with serpents licking their ears; other dramatic treatments (e.g., Euripides, Aeschylus, Seneca as reported in the surveyed sources) present related but differing emphases on Apollo's role and on Cassandra's enforced virginity. The supplied sources report these variants rather than a single definitive origin narrative.

Descriptions vary by author. Homeric epithet and passages call her the fairest or 'comeliest daughter' of Priam and compare her beauty to that of Aphrodite; Euripides depicts her as wearing a laurel crown when prophesying and describes light (xanthous) hair; Malalas offers a detailed physical portrait (shortish, round-faced, white, blondish, curly, with a priestly bearing) that emphasizes priestly dignity and youth; Dares the Phrygian gives a more modest 'moderate stature' and auburn hair with flashing eyes. Classical portrayals therefore emphasize youth, striking eyes (epithet glaukopida appears in the tradition), variable hair color across authors, and mantic accoutrement such as a laurel crown.

Cassandra's core faculty is accurate foresight: she utters true prophecies about forthcoming events (for example, forewarnings concerning Hector's death and the fall of Troy and, in later tradition, aspects of Aeneas' wanderings). The defining affliction is that, by divine dispensation in the tradition, her true predictions are never believed by others. This condition is presented as a curse originating in her relationship with Apollo in several variants and produces persistent social consequences: disbelief, confinement by her father, imprisonment or scorn by the populace, and frustration at foreseeing but being unable to avert disasters. In dramatic treatments she continues to speak publicly and to narrate events (e.g., in plays treating Agamemnon's murder), even while powerless to compel credence.
