I want to know the answer to the following question:
Who cautioned "we ought not to relate their lying fables, lest we fall under sentence of eternal death"?
All the background I'm provided with is that "Gregory of Tours read Virgil, whom he quotes in several places, along with some other Latin poets, though he cautions that "we ought not to relate their lying fables, lest we fall under sentence of eternal death."". Is that enough to answer the question?
Answer: yes
