Theodora Palaiologina Synadene

Theodora Palaiologina Synadene was a Byzantine noblewoman, daughter of Constantine Palaiologos and a half-niece of Emperor Michael VIII, who became her guardian after she was orphaned and died in 1282. She married John Synadenos and bore him three children, among them the cavalry commander Theodore Synadenos and a daughter, Euphrosyne, who became a nun.

After her husband's death she founded the convent of Bebaia Elpis in Constantinople, entered it with Euphrosyne, and composed its typikon, a rule for its organization and monastic life.
