Saints Sergius and Bacchus

Saints Sergius and Bacchus were early Christian martyrs, likely serving as officers in the Roman army around 303 CE. They were persecuted by Emperor Maximian for their refusal to sacrifice to pagan gods. After being publicly humiliated and scourged, Bacchus died, and Sergius was beheaded. Their veneration grew significantly after their deaths, with Emperor Justinian I renaming their hometown Sergiopolis and building churches in their honor, including one in Constantinople.1

Constantinople, founded by Emperor Constantine, became a major center of imperial and religious power, blending Eastern and Roman influences in its art and architecture. Byzantine architecture, characterized by domed structures and rich decoration, developed significantly in Constantinople. The Church of Saints Sergius and Bacchus, built by Justinian, is a notable example of this style, featuring a domed octagon within a rectangle. This architectural style spread throughout the Christian East and influenced regions like Russia.2345
