It's said that when the Byzantine Emperor Justinian entered his finished church for the first time in AD 536, he cried out "Glory to God that I have been judged worthy of such a work.
Oh Solomon, I have outdone you!" The Aya Sofya (formerly the Hagia Sophia) was the emperor's swaggering statement to the world of the wealth and technical ability of his empire.
Tradition maintained that the area surrounding the emperor's throne within the church was the official center of the world.
