How did constantinople's church of hagia sophia (ayasofya) demonstrate how the byzantine empire blended with the old roman empire?

The Hagia Sophia demonstrated the blending of the Byzantine Empire with the old Roman Empire through its architecture. More specifically, the bell-shaped roof at the top of the church was a nod to Roman architecture. Additionally, the many columns and arches built in the church are also typical of Roman architecture, displaying another mix between the two.
