Constantine’s tiny city in his hands is a big idea: the foundation of Constantinople declared as an act of devotion and protection under the Virgin.
Where & When
- Find the scene in the Southwest Vestibule, beside Justinian. Both figures flank the Virgin and Child, turning founding myths into liturgical proclamation.
- The composition belongs to the 10th century, reflecting how later Byzantines re‑authored origin stories for a living capital.
Constantine’s City as Symbol
- The compact city model stands for walls, forums, aqueducts, and law — all condensed into a gift.
- By presenting the city to the Virgin, the mosaic frames politics as stewardship and intercession rather than mere domination.
The Pairing with Justinian
- Facing Justinian (offering the church), Constantine (offering the city) creates a program: state and sanctuary co‑support a Christian commonwealth.
- The symmetrical layout teaches a lesson every passerby can “read.”
Reading the Style
- Gold ground empties the “background” of time and place, emphasizing theological meaning over narrative realism.
- The restrained but expressive features invite contemplation rather than spectacle.
Viewing & Photo Notes
- The vestibule can be busy; expect brief viewing windows between waves of visitors.
- Use natural light and a steady hand; angle slightly to avoid specular glare on the tesserae.

Bottom Line
In miniature, a civilization: the city itself offered back to God as a claim of responsibility and blessing.
