'''Studion Monastery''', also '''Hagios Ioannes Prodromos en tois Stoudiou''' (''Saint John the Forerunner at Stoudios'') was one of the most important [[monastery|monasteries]] at Constantinople until the fall of Constantinople to the Ottoman Turks. The rules and customs of the monastery became the model for [[monk]]s at [[Mount Athos]] and other monasteries of the Orthodox east. The monks, referred to as ''Studites'' were in the forefront of many disputes in Constantinople, particular the extended iconoclastic battles of the eight and ninth centuries.
