I want to know the answer to the following question:
In what language was most religious literature of this period written?
All the background I'm provided with is that "This was fed by the growth of the Devotio Moderna movement, most prominently in the formation of the Brethren of the Common Life, but also in the works of German mystics such as Meister Eckhart and Johannes Tauler (d. 1361).". Is that enough to answer the question?
Answer: no
