I want to know the answer to the following question:
On what wall of a church was the Last Judgment typically painted?
All the background I'm provided with is that "Romanesque art, especially metalwork, was at its most sophisticated in Mosan art, in which distinct artistic personalities including Nicholas of Verdun (d. 1205) become apparent, and an almost classical style is seen in works such as a font at Liège, contrasting with the writhing animals of the exactly contemporary Gloucester Candlestick.". Is that enough to answer the question?
