John Ioubes
John Ioubes was a Byzantine official in the middle of the 10th century at Chalcedon. He is known from the hagiography of St. Luke the Stylite. According to it, his pregnant wife was in pain for 22 days but could not give birth, until they called upon the saint's help. He is likely a descendant of Ioube, an Arab whose sons, Niketas and Chase, came to Byzantium as prisoners and entered imperial service. This Arab origin is likely why the text of the hagiography records that the surname "Ioubes" was used derisively.
