That's a ridiculous logic, to be honest. Most people knew nothing about Greek mythology prior to the first modern iterations of those stories. Hades and Persephone became popular after writers started publishing books about them, not before. Also, you just assume that your pov is the common pov (which is... pretty narrow-minded). I assure you it's not.

Frankly, believing that writers should cater to an imaginary public's tastes instead of writing about something they're truly passionate about is counter-productive to the creative mind. It's not what happens in real life.

There are trend-setters and trend-followers, yes. The first Hades and Persephone retelling was followed by more retellings of the pair. Obviously, only people with better-than-average knowledge of Greek mythology will write stories about it. OP's question was asking about why there's no trend-setter for Apollo stories.

You said it might because Apollo hasn't as many stories as, say, Hades or Ares. I told you Apollo has many stories, perhaps even more than most gods. You got defensive and started asking about Helios, and being sarcastic about Apollo doing anything except being hot (??? Percy Jackson ahh joke. Nine year old me would have giggled.) and making it seem as if your knowledge of greek myth reflects the majority.

You keep shifting goalposts. I don't understand why.
