Chapter 13. THEBES (SAINT-OMER)

The lordship of Thebes was established to the west of the March of Boudonitsa, and received homage from the lords in the valley of Dorida, including the barons of Gravia[910]. The lordship of Thebes was not one of the twelve high fiefdoms of the principality of Achaia as its territory was part of the lordship of Athens. The lordship was held jointly by the lord of Athens himself and by the head of the Saint-Omer family, after Bela de Saint-Omer married one of the sisters of the lord of Athens[911]. The Greek castle of Saint-Omer was built in the town of Thebes but was destroyed by the Catalan company. A new castle of Saint-Omer was built in 1310 on the side of Mount Movri between Larissa and Penea by Nicolas [III] de Saint-Omer Lord of Thebes and hereditary marshal of the principality of Achaia, the mountain later acquiring the name “Santameri” deriving from the original French name[912].
