I want to know the answer to the following question:
What was the name of Apollo's sister?
All the background I'm provided with is that "In Latin texts, on the other hand, Joseph Fontenrose declared himself unable to find any conflation of Apollo with Sol among the Augustan poets of the 1st century, not even in the conjurations of Aeneas and Latinus in Aeneid XII (161–215).". Is that enough to answer the question?
Answer: no
