Final answer:
The symbolical unity of Church and State in the Hagia Sophia was accounted for by architectural design, liturgical practices, and imperial patronage.
Step-by-step explanation:
The symbolical unity of Church and State in the Hagia Sophia was accounted for by architectural design, liturgical practices, and imperial patronage.
The architectural design of the Hagia Sophia, with its reserved nave for the clergy and confinement of the laity to the aisles and galleries, emphasized the hierarchical relationship between the Church and State.
Liturgical practices, such as the participation of the emperor in Church rituals, further reinforced the unity between Church and State.
Imperial patronage, as showcased by the funding and construction of the Hagia Sophia by Emperor Justinian, demonstrated the close ties between the imperial government and the Church.
