I want to know the answer to the following question:
When was the Martorana church decorated?
All the background I'm provided with is that "The mosaic depicting Roger II of Sicily, dressed in Byzantine imperial robes and receiving the crown by Christ, was originally in the demolished narthex together with another panel, the Theotokos with Georgios of Antiochia, the founder of the church.". Is that enough to answer the question?
Answer: no
