Book 9
5.3
In the time of Cadmus, the greatest power, next after his, was in the hands of the Sparti, namely, Chthonius, Hyperenor, Pelorus and Udaeus; but it was Echion who, for his great valor, was preferred by Cadmus to be his son-in-law. As I was unable to discover anything new about these men, I adopt the story that makes their name result from the way in which they came into being. When Cadnius migrated to the Illyrian tribe of the Encheleans, Polydorus his son got the kingdom.
5.4
Now Pentheus the son of Echion was also powerful by reason of his noble birth and friendship with the king. Being a man of insolent character who had shown impiety to Dionysus, he was punished by the god. Polydorus had a son, Labdacus. When Polydorus was about to die, Labdacus was still a child, and so he was entrusted, along with the government, to the care of Nycteus.
5.5
The sequel of this story, how Nycteus died, and how the care of the boy with the sovereignty of Thebes devolved on Lycus, the brother of Nycteus, I have already set forth in my account of Sicyon.See 2.6.1 When Labdacus grew up, Lycus handed over to him the reins of government; but Labdacus too died shortly afterwards, and Lycus again became guardian, this time to Laius, the son of Labdacus.
