Quartigod daughter of Helen and Paris; the only daughter of that union, named after her mother. Killed at the fall of Troy by her grandmother Hecuba — a striking inversion of the war's standard violence-against-children pattern, where the grandmother turns on the granddaughter as proxy for the unreachable mother who caused the catastrophe. The tradition is late and somewhat fragmentary but consistently transmitted across the Apollodoran-adjacent fall-of-Troy material.
