AD 691 to 1728 in the [[Church of Constantinople|Ecumenical Patriarchate]], by the [[Byzantine Empire]]<ref group="note">i.e. '''Eastern Roman Empire'''. The term Byzantine was invented by the German historian Hieronymus Wolf in 1557 but was popularized by French scholars during the 18th century to refer to the Eastern Roman Empire. The citizens of the empire considered themselves ''Romaioi'' ("Romans"), their emperor was the "Roman Emperor", and their empire the ''Basileia ton Romaion'' ("Empire of the Romans"). The Latin West designated the empire as "Romania", and the Muslims as "Rum".</ref> from AD 988 to 1453, and in Holy [[Church of Russia|Russia]] from ca. AD 988 to 1700. Derived from the [[Septuagint]] version of the Bible, it placed the date of creation at 5,509 years before the [[Incarnation]], and was characterized by a certain tendency which had already been a tradition amongst Hebrews and Jews to number the years ''from the foundation of the world'' (Latin: ''' ''[[w:Anno Mundi|Annus Mundi]] / Ab Origine Mundi'' ''' ('''AM''')).<ref group="note">Significantly, this same phrase - ''"from the foundation of the world"'' (Greek: ''Apo Kataboles Kosmou'') - occurs repeatedly in the [[New Testament]], in '''Matthew 25:34''', '''Luke 11:50''', '''Hebrews 4:3''', '''9:26''', and '''Revelation 13:8, 17:8''', perhaps reflecting on the Byzantine desire in this case to fix such an era or convenient starting point for historical computation in a calendar based on the [[Holy Scripture|Scriptures]].</ref> Its year one, the supposed date of creation, was [[September 1]], 5509 BC to [[August 31]], 5508 BC.
