You might enjoy Sophocles' Oedipus: Evidence and Self-Conviction by Fred Ahl (https://a.co/d/ditCwg5). It explores this idea, concluding that Oedipus’ investigation is flawed, but the audience is primed to believe it because they know the myth.

Sounds complex.

"All art is ultimately about the creation of art," was the kind of reductive thinking that made me drop any pretense of continuing in academia after I finished my MFA. While I thought that was a marginally better stance than taken by the folks who insisted that all "texts" were fungible (which led to one student, when we were assigned to write a review of a short fiction collection published in the last year, instead wrote a scholarly paper covering his thesis chair's years-old volume of television criticism, which the professor accepted as equivalent), the whole discussion put me off literature for years and I scuttled back to programming, where at least when things didn't make sense there was some chance of fixing them.
