I want to know the answer to the following question:
When was the mosaic at the church of Santo Stefano del Cacco destroyed?
All the background I'm provided with is that "Pope Paschal I (817–824) embellished the church of Santo Stefano del Cacco with an apsidal mosaic which depicted the pope with a model of the church (destroyed in 1607).". Is that enough to answer the question?
