I want to know the answer to the following question:
In classical times, what was Apollo's strong function in popular religion?
All the background I'm provided with is that "In classical times, his strong function in popular religion was to keep away evil, and was therefore called "apotropaios" (ἀποτρέπω, "divert", "deter", "avert") and "alexikakos" (from v. ἀλέξω + n. κακόν, "defend from evil").". Is that enough to answer the question?
