Answer:
Byzantine Empire culturally was very much devoted to religion. They built churches and monument with a painting of religious expression. The presence of Christ's presence during the crowning of the emperors shows the connection between the Church and Emperors. The paintings and mosaics in Hagia Sophia show the figures of Christ, the Virgin Mary, saints along with the emperors. Emperors are often shown holding gifts or kneeling before Christ and Mary with aureoles on their heads, represented as holy figures.
