Bartholomew II Ghisi Bartholomew II Ghisi ( ; died 1341 ) was a Latin feudal lord in medieval Greece , lord of Tinos and Mykonos , Triarch of Negroponte and Grand Constable of the Principality of Achaea . Biography . Bartholomew was the son of George I Ghisi and Alice dalle Carceri . His father died at the Battle of the Cephissus against the Catalan Company in 1311 , and his mother , who assumed regency while he was still minor , two years later . From his father , Bartholomew inherited the lordship of Tinos , Mykonos , and parts of Kea and Serifos in the Duchy of Naxos , and from his mother one of the triarchies of Euboea ( according to Loenertz the central triarchy of Chalkis ) , while his father ' s other possession by his first wife , the Barony of Chalandritsa in the Principality of Achaea , returned to a member of the Dramelay family , Nicholas of Dramelay . Batholomew married a daughter of Engilbert of Liederkerque , and had a son , George II Ghisi . Bartholomew later came to hold the post of Grand Constable of the Principality of Achaea , probably through his marriage , although he does not appear to have had lands there . In 1320 , he was taken prisoner , along with several high - ranking nobles of the Principality , by the Byzantine governor of Mystras , Andronikos Asen , at the castle of Saint George , and was sent to Constantinople . He was released in 1324 . From 1317 to 1327 Bartholomew and his fellow triarchs , backed by the Venetians , confronted the Catalans of the Duchy of Athens for the domination in Euboea . In 1326 / 27 , he reached a rapprochement with the Catalans , sealed by the marriage of his son George II to Simona of Aragon , daughter of the Catalan vicar - general Alfonso Fadrique . Bartholomew received — probably as Simona ' s dowry — half the castellany of the Castle of Saint Omer in Thebes , which he held until its destruction in ca . 1331 / 34 . This pro - Catalan attitude led to remonstrances by Venetian officials . At the same time ( 1326 / 27 ) he had a conflict for unknown reasons with the Duke of Naxos Nicholas I Sanudo and was therefore condemned by the Venetian " bailo " of Negroponte , who confiscated some of his goods while his wife was imprisoned ( by the " bailo " or Sanudo ) . The affair was judged several times at Venice but its final outcome remains unknown ; however Bartholomew must have regained his standing with Venice since he was included in its truce with the Catalans in 1331 . In 1328 , Bartholomew and his brother Marino sold their share of Kea ( half the island ) to Ruggiero Premarin . In 1331 / 32 , Bartholomew reverted to an hostile attitude toward the Catalans ( perhaps partly because of the dismissal of Alfonso Fadrique from the post of vicar - general ) and backed the titular Duke Walter VI of Brienne in his abortive attempt to reconquer his duchy . It was precisely in order to avoid the Castle of Saint Omer falling in Brienne ' s hands , that the Catalans destroyed it . According to the prologue of the French version of the famous " Chronicle of the Morea " , it derives from a prototype that Bartholomew held at the Castle of Saint Omer , and which may be the origin of the various - language versions of the " Chronicle " . Bartholomew II Ghisi died in 1341 .
