Amphion and Zethus
The first kings of the Boeotia region (before Cadmus and the flood of Deucalion) were Calydnus and Ogyges (Ogygos). The first king of the settlement that would become Thebes was Cadmus, after whom the city was originally called Cadmeia. It only became known as Thebes during the reign of Amphion and Zethus, after the latter's wife Thebe.
