Λαβδακος
Son of Polydorus and grandson of Cadmus (Table 3 and Table 29) and on Nycteis, his mother's side, the grandson of Chthonius, one of the men born from the teeth of the dragon killed by CADMUS (see also SPARTOI). His father Polydorus died when he was only one year old and his grandfather Nycteus became regent; when he too died, his brother Lycus became regent. Labdacus finally obtained power. After his reign the title passed to his son LAIUS, father of Oedipus.
The reign of Labdacus is notable for a war with King Pandion of Athens over a question of the position of the frontier. During this war, TEREUS, king of Thrace, came to help Pandion. According to a legend only recorded by Apollodorus, Labdacus, like Pentheus, was torn to pieces by the Bacchantes because he too had fought against the introduction of the cult of Bacchus.
