I want to know the answer to the following question:
In what century was the Corpus Juris Civilis rediscovered?
All the background I'm provided with is that "Canon law was also studied, and around 1140 a monk named Gratian (fl. 12th century), a teacher at Bologna, wrote what became the standard text of canon law—the Decretum.". Is that enough to answer the question?
Answer: no
