Polybus of Sicyon

Polybus (Ancient Greek: Πόλυβος) was the king of Sicyon, son of Hermes and Chthonophyle, daughter of the eponym of Sicyon. He inherited the throne of Sicyon from his grandfather; he had a daughter Lysimache or Lysianassa whom he married to Talaus of Argos. His successor was his grandson Adrastus. Some authors considered Glaucus to be his son by Euboea.
