In which year did the reign of this emperor, who convoked the Second Council of Constantinople, end?
Second Council of Constantinople The Second Council of Constantinople is the fifth of the first seven ecumenical councils recognized by both the Eastern Orthodox Church and the Roman Catholic Church. It is also recognized by the Old Catholics and others. Protestant opinions and recognition of it are varied. Some Protestants, such as Calvinists and Lutherans, recognise the first four councils, whereas most High Church Anglicans accept all seven. Constantinople II was convoked by the Byzantine Emperor Justinian I under the presidency of Patriarch Eutychius of Constantinople. It was held from 5 May to 2 June 553. Participants were overwhelmingly Eastern bishops only sixteen Western bishops were present, including nine from Illyricum and seven from Africa, but none from Italy out of the 152 total.

He is not to be confused with the much earlier philosopher John Philoponos.
