Constantine XI Palaiologos
Patapios' relic after the destruction of the Monastery of the Egyptians in 536 AD was transferred by Saint Varas to the Monastery of Saint John at Petrion, which during the last centuries of the Byzantine Empire was under the protection of the royal family of Constantinople, the Palaiologoi, and especially the "Augusta" Helena Dragaš, the mother of the last Byzantine emperor, Constantine XI Palaiologos, who became a nun and a saint under the monastic name of Saint Hypomone ("patience").
