Mortal Theban prince and king, the only son of Cadmus and Harmonia (greek_harmonia, whose notes name 'Polydorus of Thebes'). Brother of Autonoe, Ino, Semele and Agave. Husband of Nycteis and father of Labdacus, founder of the Labdacid line (Laius, Oedipus). Authored as mortal — the human Theban royal line — matching the existing sister greek_autonoe. Id is greek_polydorus_thebes to disambiguate from the existing greek_polydorus_troy (Polydorus son of Priam, an unrelated figure).
