I want to know the answer to the following question:
What deity does the 12th century mosaic in the Hagia Sophia depict?
All the background I'm provided with is that "The only surviving 12th-century mosaic work in Constantinople is a panel in Hagia Sophia depicting Emperor John II and Empress Eirene with the Theotokos (1122–34).". Is that enough to answer the question?
Answer: yes
